    A dispenser (10) of one or more fluid or pasty products comprises: a dispenser body (12); a dispensing head (22) guided in rotation with respect to the dispenser body (12) about a reference axis (100) of the dispenser, the dispensing head (22) having at least one dispensing orifice (66); and a pumping assembly (14) having at least a first pump (16A, 16B, 16C) having a tubular nozzle (54A, 54B, 54C) defining a first ejection axis (200A, 200B, 200C) fixed relative to the distributor body (12) and parallel to the reference axis (100) of the distributor, the nozzle (54A, 54B, 54C) of the first pump (16A, 16B, 16C) being movable in translation relative to the distributor body (12) parallel to the first ejection axis (200A, 200B, 200C). The dispensing head (22) is fixed in translation relative to the distributor body (12), and the distributor (10) further comprises a kinematic connection (24) between the dispensing head (22) and the nozzle (54A, 54B, 54C), to transform a rotational movement without translation of the dispensing head (22) relative to the dispenser body (12) about the reference axis (100) of the dispenser in a non-rotational translation movement of the nozzle (54A, 54B, 54C) relative to the distributor body (12) parallel to the reference axis (100) of the dispenser.

    TECHNICAL FIELD OF THE INVENTION The invention relates to a portable dispenser for one or more fluid products, for example one or more cosmetic care, makeup or perfume products, and / or a or more pharmaceutical products. Here, the expression "fluid products" will include liquid products, as well as creams and pasty products which are sufficiently malleable to be dispensed by means of pumps.
    STATE OF THE PRIOR ART In the document FR2822655, a cosmetic product dispenser is described comprising: a dispenser body, a dispensing head guided in rotation relative to the dispensing body around a reference axis of the dispenser, the dispensing head comprising a dispensing orifice, and a dispensing pump provided with a tubular nozzle defining an ejection axis coincident with the reference axis of the distributor, the nozzle being movable in translation relative to the distributor body parallel to the ejection axis. The dispensing head is provided with two lugs which engage in two grooves forming helical ramps of the dispenser body. To dispense the product, the user turns the dispensing head which follows a helical trajectory and presses down the nozzle to deliver a dose of product.
    The return to the starting position of the head is obtained by a rotation of the head in the opposite direction under the thrust of the spring of the pump which repels the nozzle. To allow this movement, the pitch of the propeller must be chosen so as to guarantee the reversibility of the movement transformation mechanism. It follows that an axial force applied to the dispensing head parallel to the reference axis of the dispenser causes the dispensing head to pivot and sink. We cannot therefore guarantee, in uncontrolled storage conditions, for example in a travel case, that the product will not be ejected inadvertently.
    Furthermore, the direct kinematic connection between the dispensing head and the body of the dispenser, produced by the lugs and the ramps, imposes parts of relatively complex shape with numerous undercuts, the production of which by molding requires molds to drawers.
    The size of this kinematic connection also requires a certain height of the dispensing head, depending on the useful stroke of the nozzle.
    Without specific protection provisions, the reciprocating movement of the dispensing head relative to the body of the dispenser can promote the penetration of foreign matter into the variable gap between the dispensing head and the body of the dispenser. These foreign materials can compromise the cleanliness or even the functioning of the dispenser.
    Finally, this dispenser imposes an alignment of the axis of rotation of the dispensing head with the nozzle of the pump, and is suitable neither for a dispenser whose nozzle would be offset, nor for a dispenser having to actuate several pumps.
    PRESENTATION OF THE INVENTION The invention aims to remedy at least some of the drawbacks of the state of the art and to propose a distributor that is easy to use and insensitive to the forces exerted axially on the dispensing head.
    To do this is proposed, according to a first aspect of the invention, a distributor of one or more fluid or pasty products comprising:
    a distributor body;
    a distribution head guided in rotation relative to the distributor body about a reference axis of the distributor, and fixed in translation relative to the distributor body, the distribution head comprising at least one distribution orifice;
    a pumping assembly comprising at least a first pump comprising a tubular nozzle defining a first ejection axis fixed relative to the distributor body and parallel to the reference axis of the distributor, the nozzle of the first pump being movable in translation by relation to the distributor body parallel to the first ejection axis; and a kinematic connection between the dispensing head and the nozzle, to transform a rotational movement without translation of the dispensing head relative to the dispenser body around the reference axis of the dispenser into a translational movement without rotation of the nozzle relative to the distributor body parallel to the distributor reference axis.
    The absence of translational movement of the dispensing head makes it possible to limit its height, and to simplify the forms of guiding the rotational movement of the dispensing head relative to the body of the dispenser. The simplified forms are thus capable of being obtained by an injection molding process, in a mold whose parts are movable relative to each other in translation only, by an axial movement preferably parallel to the reference axis.
    The body of the dispenser may be made of glass or of molded material.
    According to one embodiment, the kinematic connection between the dispensing head and the nozzle comprises an annular guide track located at constant distance from the reference axis of the dispenser and having one or more undulations in an axial direction parallel to the reference axis of the dispenser and a set of one or more sliding surfaces cooperating with the annular guide track, the annular guide track and the set of one or more sliding surfaces being arranged in such a way that a rotation of the dispensing head around the reference axis of the distributor causes a relative translation between the annular guide track and the assembly of one or more sliding surfaces parallel to the reference axis of the distributor, combined with relative rotation between the annular guide track and the assembly of one or more self-sliding surfaces ur of the distributor's reference axis. Preferably, the assembly of one or more sliding surfaces is formed by a groove open in an axial direction, the annular guide track penetrating into the groove, in contact with a corrugated bottom of the groove. If necessary, the groove can also contribute to guiding the dispensing head in rotation about the reference axis.
    According to a particularly advantageous embodiment, the annular guide track is continuous and makes it possible to carry out a complete revolution of the dispensing head around the reference axis of the dispenser. This continuity allows the user to use the dispenser without worrying about any initial position. Preferably, the position of the pumping assembly and the kinematic connection between the dispensing head and the nozzle reached at the end of a revolution is identical to the starting position and corresponds to an integer number of pumping cycles, number which can be greater than or equal to one.
    According to a preferred embodiment, the annular guide track and the assembly of one or more sliding surfaces are arranged in such a way that the dispensing head can rotate around the reference axis of the dispenser in a direct and in a retrograde direction, preferably over more than one turn. The desired transformation of the rotation movement without translation of the dispensing head into a translation movement without rotation of the nozzle is thus obtained in the two directions of rotation of the distribution head.
    According to one embodiment, the distributor body comprises:
    a cylindrical guide surface turned radially towards the reference axis of the distributor and situated opposite a cylindrical guide surface of the distribution head for guiding the distribution head in rotation about the reference axis of the distributor with respect to to the distributor body; and / or a cylindrical guide surface turned radially away from the reference axis and located opposite a cylindrical guide surface of the dispensing head to guide the dispensing head in rotation about the axis of distributor reference in relation to the distributor body.
    These guide surfaces contribute to guiding the dispensing head in rotation relative to the body of the dispenser.
    According to one embodiment, the body of the dispenser comprises:
    an annular guide surface, preferably planar, turned axially opposite the dispensing orifice, opposite a guide surface complementary to the dispensing head and / or an annular guide surface, preferably planar, turned axially towards the dispensing orifice, opposite a complementary guide surface of the dispensing head.
    These annular guide surfaces contribute to the axial guidance of the dispensing head relative to the body of the dispenser.
    According to one embodiment, the dispensing orifice is aligned with the reference axis of the dispenser. Depending on the type of product dispensed, the dispensing orifice may open onto a flat, concave or convex surface of the dispensing head. A concave surface forming a bowl will be preferred in particular if the product dispensed is relatively fluid, or if it is desired that the user can mix the dispensed product or products before their application.
    According to a particularly advantageous embodiment, it is provided that between the pumping assembly and the dispensing head is interposed a pusher linked to the dispenser body by a slide link capable of guiding a translational movement without rotation of the pusher relative to the distributor body, the pusher being capable of pressing on the nozzle of the first pump when the distribution head rotates relative to the distributor body about the reference axis. The pusher is a member separate from the dispensing head and from the dispenser body, forming part of the kinematic connection between the dispensing head and the nozzle. The pusher is preferably constituted by two parts integral with each other, preferably each obtained by molding, preferably able to be each obtained by molding in a mold, the parts of which are movable relative to each other in translation parallel to the reference axis. The desired kinematics is thus obtained with simple geometries, therefore simple tools.
    Preferably, the pusher comprises at least a first distribution conduit for channeling a first fluid escaping from the nozzle of the first pump towards the distribution orifice. In the hypothesis where the first ejection axis is coincident with the reference axis and with the axis of the dispensing orifice, the first dispensing duct has an essentially axial orientation. In the event that the first ejection axis is distant from the reference axis and the axis of the dispensing orifice, the first dispensing conduit has a section of radial orientation relative to the axis of distributor reference and the first ejection axis.
    Where appropriate, there is provided a sleeve of variable length formed between an outlet of the first distribution duct and the dispensing orifice, capable of channeling the first fluid between the outlet of the first dispensing duct and the dispensing orifice . The variable length conduit makes it possible to manage the variations in distance between the outlet of the first distribution conduit and the distribution orifice, when the distribution head rotates around the reference axis. This variable length conduit can be produced by two tubes sliding one inside the other, one of the tubes being integral with the dispensing head and the other with the pusher. It can also be produced by a deformable sleeve, for example an accordion, positioned between the pusher and the dispensing head.
    According to a particularly advantageous embodiment, the pumping assembly comprises at least a second pump comprising a tubular nozzle defining a second ejection axis fixed relative to the distributor body and parallel to the first ejection axis, the nozzle of the second pump being movable in translation relative to the distributor body parallel to the second ejection axis, the plunger being able to press on the nozzle of the second pump when the distribution head rotates relative to the distributor body around the distributor's reference axis, and comprising a second distribution conduit for channeling a fluid escaping from the nozzle of the second pump towards the distribution orifice. The pusher then constitutes an intermediate member between the dispensing head and the two nozzles of the pumping assembly. The jets of the two pumps preferably have an identical useful stroke. It can however be envisaged that one of the two pumps has a shorter useful stroke than the other, in which case a dead stroke of the pusher can be provided before the pusher comes to bear on the nozzle of the pump whose useful stroke is the shortest.
    The two pumps can if necessary immerse in the same tank containing a fluid or pasty product, to deliver a large volume of product, for a short stroke of the pusher.
    Alternatively, the two pumps can dive into separate tanks, to deliver separate products, which are mixed at the time of dispensing, at the dispensing orifice or slightly upstream. According to one embodiment, the distributor body has a wall delimiting a peripheral reservoir into which a pump body of one of the first and second pumps opens, the other of the first and second pumps comprising a pump body immersed in another tank preferably housed inside the peripheral tank. The tank wall of the dispenser body can be opaque or transparent. Likewise, the internal tank can be opaque or transparent. The transparency of the walls makes it possible in particular to visualize the levels of the fluids contained in the tanks.
    According to one embodiment, one of the ejection axes is coincident with the reference axis of the dispenser, the other being offset, which however requires care in guiding the pusher which is likely to be stressed by forces, the result of which is not in the reference axis, generating a parasitic torque.
    According to another embodiment, the two ejection axes are offset from the reference axis. The three axes can be coplanar to optimize the direction of the resulting force on the pusher, or not.
    According to a particularly advantageous embodiment, the pumping assembly comprises at least a third pump, comprising a tubular nozzle defining a third ejection axis fixed relative to the distributor body and parallel to the first ejection axis, the nozzle of the third pump being movable in translation relative to the distributor body parallel to the third ejection axis, the pusher being capable of pressing on the nozzle of the third pump when the distribution head rotates relative to the distributor body around of the distributor's reference axis, and comprising a third distribution conduit for channeling a fluid escaping from the nozzle of the third pump towards the distribution orifice. The three axes of ejection can be coplanar, or form an isosceles triangle, or even equilateral, to minimize the bulk. One of the three ejection axes can if necessary be confused with the reference axis. The three pumps can dive into three separate chambers to pump three separate fluids corresponding, if necessary, to three separate products to be mixed. Alternatively, two of the three pumps can dive into a common enclosure, which allows, for a given stroke of the pusher, to obtain very different proportions for the fluid delivered by a single pump and for the fluid delivered by two pumps in parallel.
    Preferably, the distributor body has one or more walls defining a fixed volume tank into which opens at least one pump body of a pump of the pumping assembly, the wall or walls preferably comprising one or more several outer walls of the distributor body.
    Preferably, the dispenser comprises at least one variable volume reservoir comprising at least one movable wall and into which a pump body of a pump of the pumping assembly is immersed. According to one embodiment, the variable volume reservoir is formed by a cylindrical barrel closed by a piston. Alternatively, the variable volume reservoir is formed by a deformable pocket.
    In the event that the distributor has several reservoirs, all may be of fixed volume or of variable volume, or some may be of fixed volume and others of variable volume.
    According to a second aspect of the invention, it relates to a distributor of one or more fluid or pasty products comprising:
    a distributor body;
    a dispensing head guided in rotation relative to the dispenser body about a distributor reference axis, with or without translation, the dispensing head comprising at least one dispensing orifice;
    a pumping assembly comprising at least a first pump comprising a tubular nozzle defining a first ejection axis fixed relative to the distributor body, parallel to the reference axis of the distributor and distant from the reference axis of the distributor, the nozzle of the first pump being movable in translation relative to the distributor body parallel to the first ejection axis;
    a kinematic connection between the dispensing head and the nozzle, to transform a rotating movement of the dispensing head relative to the body of the distributor around the reference axis of the distributor into a translational movement without rotation of the nozzle relative to the body of the distributor parallel to the reference axis of the distributor.
    It is thus possible to offset the axis of the nozzle with respect to the reference axis.
    Preferably, the dispensing orifice is aligned with the reference axis.
    According to a particularly advantageous embodiment, the dispenser further comprises a pusher bearing on the nozzle of the first pump, and comprising a first distribution conduit for channeling the first fluid escaping from the nozzle of the first pump to the dispensing orifice. The first distribution conduit preferably has a radial orientation with respect to the reference axis of the distributor and to the first ejection axis.
    If necessary, the distributor according to this second aspect of the invention may have all or part of the characteristics of the distributor according to the first aspect of the invention, with the same advantages.
    According to a third aspect of the invention, it relates to a distributor of one or more fluid or pasty products comprising:
    a distributor body;
    a dispensing head guided in rotation relative to the dispenser body about a distributor reference axis, with or without translation, the dispensing head comprising at least one dispensing orifice;
    a pumping assembly comprising at least a first pump comprising a tubular nozzle defining a first ejection axis fixed relative to the distributor body, parallel to the reference axis of the distributor, the nozzle of the first pump being movable in translation by relation to the distributor body parallel to the first ejection axis;
    a pusher resting on the nozzle of the first pump, and comprising a first distribution conduit for channeling the first fluid escaping from the nozzle of the first pump towards the distribution orifice, a sliding connection between the distributor body and the pusher for guiding a translational movement without rotation of the pusher relative to the body of the dispenser;
    a kinematic connection between the dispensing head and the pusher, to transform a rotating movement of the dispensing head relative to the body of the distributor around the reference axis of the distributor, with or without translation, into a translation movement without rotation of the nozzle relative to the body of the distributor parallel to the reference axis of the distributor.
    The pusher allows control of the translational movement of the sprinkler (s), and makes it possible to avoid parasitic forces being transmitted to the sprinkler perpendicular to the reference axis.
    If necessary, the distributor according to this third aspect of the invention may have all or part of the characteristics of the distributors according to the first aspect of the invention or the second aspect of the invention, with the same advantages.

    DETAILED DESCRIPTION OF EMBODIMENTS With reference to FIGS. 1 and 2, a portable distributor 10 according to an embodiment of the invention comprises a distributor body 12, a pumping assembly 14 comprising three parallel pumps 16A, 16B, 16C, a dispensing head 22 covering the pumping assembly 14, movable in rotation relative to the dispenser body 12 around an axis of revolution 100 which is also a reference axis of the dispenser 10, a kinematic connection 24 between the dispensing head 22 and the pumping assembly 14, and an optional outer cover 26.
    For the following description, it will be arbitrarily considered that the cover 26 is located "above" the body 12 of the dispenser, and that the reference axis 100 of the dispenser is oriented vertically. We will thus use the term "upper" to designate what is turned upwards or what is "above", and the term "lower" to designate what is turned towards "down" or what is "Below".
    As illustrated in particular in Figures 3 and 4, the body 12 of the dispenser 10, of cylindrical outer shape with an oval or elliptical base centered on the reference axis 100 of the dispenser, comprises a base 28, a shroud 30 attached on the base, a barrel 32 housed in an enclosure formed by a cylindrical external wall 36 of the base, and a support plate 38 pinched between the hoop 30 and the base 28. The plate 38 is in abutment against a flange upper annular of the base 28 with the interposition of a seal, and against an upper annular rim of the barrel 32 with the interposition of another seal, so as to delimit two non-communicating tanks 40, 42, one 40 inside the barrel 32, the other 42 in the part of the enclosure not occupied by the barrel 32. The base 28 has a bottom 44 having a central cylindrical opening 46, in which is embedded l 'extr axial mite was 32 opposite the plate 38, said axial end being pierced by one or more apertures 48 (Figure 4).
    The plate 38 is provided with three housing wells 50A, 50B, 50C, each for housing one of the pumps 16A, 16B, 16C of the pumping assembly 14. Each pump 16A, 16B, 16C, has a body of pump 52A, 52B, 52C snapped into the associated well 50A, 50B, 50C, an internal mechanism of known type, and a tubular nozzle 54A, 54B, 54C movable in translation relative to the pump body 52A, 52B, 52C between a position of rest and a depressed position, for both actuating the mechanism of the associated pump 16A, 16B, 16C and delivering by its outlet orifice a dose of the pumped fluid. The axis of translation of each nozzle 200A, 200C, 200C, referred to below as the ejection axis, is parallel to the reference axis 100 of the distributor 10. Two of the three pumps 16B, 16C open into the reservoir 42 located at outside the barrel, the third 16A, central, opening into barrel 32. Optionally, seals can be placed in each well 50A, 50B, 50C to ensure or reinforce the seal around the pump body 52A, 52B , 52C associated. Thus the tank 42 located outside the barrel 32 has a constant volume and completely sealed with respect to the outside, the only communication with the outside being carried out by means of the pumps 16B, 16C, which are of the return air pump type. The barrel 32 is in turn equipped with a sliding piston 56, sealingly separating the reservoir 40, the volume of which is variable, from a volume connected to the outside by the openings 48. The pump 16A plunging into the barrel 32 is a pump without air intake. In this embodiment, the ejection axes 200A, 200B, 200C are located in a common plane which contains the reference axis 100 of the distributor 10.
    The plate 38 is also provided with two guide tubes 58 and four axial stops 60, which project towards the dispensing head 22 and are each provided with a pair of indexing lugs 62.
    The dispensing head 22 has a bottom 64 pierced with a dispensing orifice 66 centered on the reference axis 100, and a cylindrical outer wall 68 provided at its free end with a guide flange 70, which comes insert into a reserved annular space, axially delimited by the axial stops 60 of the plate 38 and by an annular shoulder 72 plane formed at the free end of the hoop 30, and radially by a cylindrical guide bearing formed by the inner wall of the hoop 30, so as to achieve the guiding in rotation without translation of the dispensing head 22 relative to the body 12 of the dispenser 10 around the reference axis 100. The flange 70 has four notches, each serving as a housing for an indexing tab 76.
    The bottom 64 of the dispensing head 22 has an outer face, turned away from the plate 38, shaped in a bowl centered on the dispensing orifice 66, and an inner face, provided with a cylindrical inner skirt 78 projecting towards the plate 38 (FIG. 6). This skirt 78 has an end flange, situated at a constant distance from the reference axis of the dispenser, which forms an annular guide track 80 and has one or more undulations, in this case four in number, in one direction. axial parallel to the reference axis 100 of the distributor 10.
    Between the bottom 64 of the dispensing head 22 and the plate 38 of the body 12 of the dispenser 10 is arranged a pusher 82 which constitutes, with the annular guide track 80, the kinematic connection making it possible to transform the rotational movement of the dispensing head 22 in a translational movement of the nozzles 54A, 54B, 54C.
    The pusher 82 consists of two parts 82.1.82.2 in the form of discs, fixed to each other by gluing or any other suitable means. The pusher 82 is positioned inside the outer wall 68 of the dispensing head 22, and has a circular outer rim in sliding contact with the inner face of the outer wall 68.
    As illustrated more particularly in Figure 6, the pusher 82 has, on its upper face facing the bottom 64 of the dispensing head 22, two coaxial cylindrical walls 84 between which is formed a groove 86 whose bottom 88 has corrugations which, in a reference angular position of the dispensing head 22 relative to the pusher 82, are complementary to the corrugations of the annular guide track 80. The groove 86 is formed so as to allow the inner skirt 78 of the dispensing head 22 to be inserted between the two coaxial walls 84, with a small spacing or in sliding contact.
    On the upper face of the pusher is formed an outlet orifice 90, positioned opposite the dispensing orifice 66 of the dispensing head 22, the two orifices 66, 90 being aligned on the reference axis 100 of the distributor 10. A bellows sleeve 92 forms a conduit of variable length between the two orifices 66, 90. The bellows sleeve 92 can optionally form a valve.
    As illustrated in Figure 7, the pusher 82 has, on its underside facing the plate 38, two guide tubes 98 which are inserted into the guide tubes 58 of the plate 38 to form a telescopic connection of guiding in translation of the pusher 82 relative to the plate 38 parallel to the reference axis 100 of the distributor 10.
    On the underside of the pusher 82 are formed tubular sleeves 94A, 94B, 94C into which are inserted, preferably with a tight fit, the nozzles 54A, 54B, 54C. Distribution conduits 96A, 96B, 96C are provided in the pusher to connect the nozzles 54A, 54B, 56C to the outlet orifice 90, in this case a purely axial conduit 96A for the pump 16A aligned on the axis of the reference 100 of the distributor 10, and of the conduits 96B, 96C extending radially for the other two pumps 16B, 16C.
    The distributor 10 operates in the following manner:
    In an angular reference position of the dispensing head 22 relative to the body 12 of the dispenser 10, the contact between the guide track 80 and the bottom 88 of the groove 86 is surface and the distance between the upper face of the pusher 82 and plate 38 is maximum. The nozzles 54A, 54B, 54C of the pumps are at their top dead center and the springs (not shown) integrated in each of the pumps 16A, 16B, 16C repel the nozzles 54A, 54B, 54C and, through them, the pusher 82, parallel to the reference axis 100, so that the flange 70 of the dispensing head 22 bears axially against the shoulder 72 formed by the hoop 30 of the body 12 of the dispenser 10. This position is therefore a position of balanced. The indexing tabs 76 are each retained by one of the pairs of lugs 62, so that this position is an indexed position.
    To obtain the distribution of a dose of product, the user rotates the dispensing head 22 relative to the body 12 of the dispenser 10 about the reference axis 100, from the indexed starting position to the next indexed position defined by the indexing tabs 76 and the pairs of indexing lugs 62, on a quarter turn. The elastic locking of the indexing tabs 76 between the lugs 62 on arrival in the new indexed position can be perceived by the user by touch or by ear.
    The rotation of the dispensing head 22 relative to the pusher 82 requires a relative sliding movement between the guide track 80 and the bottom 88 of the guide groove 86. Over approximately the first half of the angular travel, therefore on an eighth of a turn, the relative movement of the guide track 80 and the bottom 88 of the guide groove 86 generates, by a cam effect, an axial movement of the pusher 82 towards the plate 38, pushing back the nozzles 54A, 54B , 54C against the force of the springs integrated into the mechanisms of the pumps 16A, 16B, 16C. The amplitude of this movement is such that the nozzles 54A, 54B, 54C cover at least part e of their useful translational travel sufficient to trigger a pumping cycle. The fluid in the central reservoir 40, supplied by the central pump 16A, and the fluid in the peripheral reservoir 42, supplied by the pumps 16B, 16C, mix at the outlet orifice 90 and are conveyed to the orifice distribution 66 where the user can use them. The proportions of the two fluids depend on the respective volumes of the pumps 16A, 16B, 16C. On the residual part of the rotation up to the final indexed position, the springs of the pump mechanisms push the nozzles 54A, 54B, 54C which cause the push rod 38 to rise to the high position.
    The description thus made of a quarter-turn pumping cycle is preferably independent of the direction of rotation of the dispensing head 22, which can be either direct or retrograde. To ensure that the forces required to activate the pumps by direct or retrograde rotation are identical, appropriate symmetries of the guide track 80 on the one hand and of the bottom 88 of the guide groove 86 on the other hand are provided. Furthermore, nothing prevents the user from turning the dispensing head 22 always in the same direction, therefore over more than one revolution, each quarter of a revolution corresponding to a pumping cycle.
    Naturally, many modifications are possible.
    The number of pumps and tanks may vary. For example, there may be only one pump, aligned with the reference axis, or offset from the reference axis, and immersed in a single tank. There can be two pumps, immersing in the same tank or in two separate tanks, and which can have a symmetrical positioning of one another on either side of the reference axis, or one of which is aligned with the reference axis and the other offset. It is also possible to envisage embodiments with three pumps arranged at the vertices of an equilateral triangle centered on the reference axis, or at the vertices of an isosceles triangle whose vertex is aligned with the reference axis, as alternatives to embodiment with three coplanar pumps illustrated in the figures. Providing more than one pump for a given reservoir makes it possible, on the one hand, to increase the dose delivered for a given translational stroke of the pusher 82, and on the other hand to balance the forces on the pusher 82.
    The useful strokes of the pumps can be identical, or different. In this hypothesis, one can for example provide that the pusher is integral with the nozzle having the greatest useful stroke, and that the nozzles of the other pumps are slidably mounted in the tubular sleeves 94A, 94B, 94C of the pusher.
    The attachment of the pump (s) 16A, 16B, 16C to the body 12 of the distributor 10 can be carried out by any suitable means.
    The general shape of the body 12 of the dispenser may vary. The distribution head 22 is preferably cylindrical, but other choices can be made, in particular a distribution head having a symmetry of revolution of order N around the reference axis 100, N a number integer for example equal to the number of pumping cycles obtained over one revolution of the dispensing head 22.
    The pumps 16A, 16B, 16C can if necessary be all without air intake. To this end, provision can be made for the reservoir 42 to have a piston similar to the piston 56, or for each of the two pumps 16B, 16C to be immersed in a flexible pocket of variable volume. The bottom 44 of the base must then be provided with openings for bringing the outer wall of the pocket (s) or piston to atmospheric pressure.
