    ADJUSTABLE VALVE FOR AN AIR DUCT IN A VENTILATION SYSTEM Technical Field that at least no Luchikanaal is fitted with a ventilation apparatus connected to the Luchikanaal, in which such a valve assembly is arranged.
    Background Art Many buildings have air ducts that provide passageways for exchange, ventilation, circulation and/or movement of air through the surfaces (e.g. walls and ceilings) of the building. Buildings may have ventilation systems that take in "fresh" air from bubbles into the building and exhaust "exhausted" air from within the building. Fresh air may be taken into a building or exhaust air may be exhausted from a building through one or more air ducts. Some buildings include other systems and/or devices, such as air conditioning systems, heating systems and bathroom fans, which use air ducts to provide routes for the movement of air through the surfaces of the building.
    Typically, an air duct is associated with a valve connecting the air duct to a room of the building. A valve provides a passageway in fluid communication with the associated air duct to allow airflow through a building surface. Some valves have flow control mechanisms. Such mechanisms allow the flow of air through the valve to be controlled. The valve may include a lid for a more aesthetic appearance to the user.
    Object of the invention The object of the invention is to provide an improved tilt, which can be adjusted manually when installed in the air duct.
    © BE2021/5028 Summary of the Invention Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and provide at least the advantages described below.
    Thus, one aspect of the present disclosure is the provision of a valve for mounting in or on an air duct for ventilation of a home, the air duct! can for example end up in the floor or just ceiling of a room of the house.
    The valve is also suitable for use with an air duct for the supply of air to the room or an air duct for the exhaust of air to the room.
    The valve encompasses a staff with an annular stator element adapted to be mounted, preferably in said air duct, an outer rotor portion provided in the space defined by the annular stator element, an inner rotor portion arranged in the space between the stator and the outer rotor portion is embedded and connected to it.
    In particular, the inner and outer rotor portions are rigidly connected to each other so that the rotation of the outer rotor portion causes the rotation of the inner rotor portion.
    In addition, the outer rotor portion can be retained in the space defined by the annular stator element by means of additional fasteners, for example a screw or the like which projects into a recessed surface of the outer rotor element to secure the outer rotor portion, and thereby also the inner rotor portion, mechanically held in the annular stator element.
    The valve is further adapted to adjust the axial position of the inner rotor portion relative to the outer rotor portion, preferably in discrete steps, when the outer rotor portion is rotated, i.e., rotated about its central axis A.
    Thus, the cross section of an air passage between the outer rotor portion and the inner rotor portion is changed, thereby changing the air flow or air pressure through the valve.
    In this way, an improved valve, which is manually adjustable when installed in the air duct, is provided.
    In particular, the valve described is compact and efficiently designed and does not require the presence of any parts, for example a cover, in the space connected to the air duct.
    However, the tip can partially come out of the air duct.
    According to one embodiment, the present invention relates to the valve as described above, wherein the stator includes at least one inner slot provided on the inner surface of the stator for receiving and guiding at least one projection mounted on the outer surface of an annular inner rotor element of the inner rotor portion is provided.
    The minimum
    BE2021/5028 One inner slot is adapted to adjust the axial position of the inner rotor portion relative to the stator and the outer rotor portion when the inner rotor portion is rotated relative to the stator.
    According to another embodiment, the present invention relates to the valve as described above, furthermore collapsing visual cues, corresponding to the axial position of the inner rotor portion, on the side configured to face a chamber of the housing when the valve is closed. is held in the air duct. In another embodiment, the present invention relates to the above-described valve assembly, further comprising removable locking means adapted to prevent rotation of the outer rotor portion. A further aspect of the present disclosure is provided with a mechanical ventilation system encompassing a ventilation device which is connected to an air duct and in which a valve as described above is arranged. Other aspects, advantages, and salient features of the disclosure will become apparent to those skilled in the art from the following detailed description, which, in conjunction with the accompanying drawings, discloses various embodiments of the present disclosure.

    Detailed Description Figures 1 and 2 show a valve assembly 1 for use in an air duct of a mechanical or natural ventilation system of a house or the like.
    The illustrated valve assembly 1 includes an annular housing 40 in which an adjustable valve 10 of the valve assembly 1 is mechanically retained via an annular coil spring 140. The valve assembly 1 further includes an armature 20, 23 connected to and extending from one side of the valve. 10, which is directed towards a space of the house, into which the air duct debouches, when the housing 40 is attached to an inner wall of the air duct.
    The housing 40 has an outer side of the housing 41 adapted for connection to said air duct and an inner side of the housing 42 opposite the outer side of the housing 41 adapted for connection to the adjustable valve 10. The valve 10 comprises adjusting means and flow control means for controlling the flow or pressure of the air flowing through the housing 40 based on the position of the adjusting means.
    The armature 20, 23 comprises a armature body 20 adapted to be connected to said adjusting means to control the position of the adjusting means, thereby controlling the airflow or air pressure flowing through the housing 40 and in the direction of the space is arranged when the housing 40 is attached to an inner wall of the air duct.
    The proximal end 21 of the armature body 20 is adapted to be connected to the adjustment means such that axial rotation of the armature body 20 changes the position of the adjustment means and point rotation of the armature body 20 changes the direction of the armature body B relative to the valve 10 changes without changing the position of the
    > BE2021/5028 adjusting means, as shown in figures 7A and 7B. The distal end 21, opposite the proximal end 22, of the luminaire body 20 is adapted for reception and connection to a light source 23, e.g., a LED, via an electrical connection adapted for connection to a power source.
    In addition, when the housing 40 is larger than the tilt 10 in the flow direction, the tilt assembly 1 may comprise an annular guide member 30 for directing the air from the end of the housing to a space to the opening at the end of the valve to a space . Like the valve 10, the guide member 30 can be mechanically retained via an annular coil spring 31.
    The ring springs 140, 141 are adapted to be inserted into an annular slot 31, 134 of the valve 10 or guide member 30 to secure (lock and hold) the respective part to the housing 40. The coil springs can be, for example, compression springs and/or canted coil springs. The advantage is that the coil spring 140, 141 produces such a radial or axial force that the coil spring 31, 140 remains in contact! with the mating surface and large fit tolerances, can compensate for misalignment and surface irregularities.
    Figures 3, 4A-B, 5A-B and 6A-B show an adjustable valve 100 for use in an air duct of a mechanical or natural ventilation system of a house or the like. The adjustable valve 100 comprises a stationary part 130, also called a stator, adapted to be stationary connected to this air duct, and a rotatable assembly 110, 120, also called a rotor, rotatably connected to this stator 130. The rotatable assembly comprises a inner roller portion 120 and an outer rotor portion 110.
    As can be seen in figures 4A-B, the outer rotor part 110 is formed by an annular outer rotor element 111 which is connected via a plurality of spacers 115 to a central cup-shaped element 113, preferably symmetrically around the cup-shaped element 113, at the upper end of the outer rotor element 111. The outer rotor element 111 overturns a plurality of parallel slots 112 extending from the lower end of the annular element 111 facing the stator 130, and these slots 112 are preferably symmetrical about the cup-shaped element 113 is positioned. The outer rotor element 111 further includes a plurality of recessed surfaces 116 on the outer surface extending between the succeeding grooves 112 in an angular direction and a plurality of corrugated surfaces 117 on the lower end of the outer surface extending between the
    > BE2021/5028 subsequent slots 112 in the angular direction uilstreki. In the cup-shaped element 113, a connecting element 114 can be arranged for connection to an electrical body.
    As can be seen in Figure 5A-B, the inner rotors are! 120 formed by an annular inner rotor member 121. At the upper end of this inner rotor member 124, which is disposed toward the outer rotor member 110 and away from the stator 130, the inner rotor member 120 is provided with an annular member 126 located extending inwardly from the inner surface 122 of the inner rotor member and having a plurality of projections 125 on the bump surface 123 opposite the inner surface 122 of the annular member 121. The plurality of projections 125 of the inner rotor member 120 and the plural parallel slots 112 of the outer rotor part 110 are placed in corresponding angular positions in the angular direction, preferably symmetrically around the respective annular element. When the inner rotor portion 120 is inserted into the outer rotor portion 110, each projection 125 extends through a respective slot 112 to a widened portion of the projection! 127 provided outside the outer rotor part 110, the width of the widened part of the projection 127 being greater than the width of the respective slot 112. Thus, the projection 125 prevents the inner and outer rotor elements 111, 121 from being moved to each other. in a plane perpendicular to the axial direction A, e.g. by translation in the radial direction or by rotation in the angular direction.
    As shown in Figures GA-B, the stator 130 is formed by an annular stator element 131 in which an outer slot 134 is provided on the outer surface 133 of the stator element 131 to receive the annular coil spring 140, shown in Figure 3, about the stator 130. mechanically retained in the air channel, and wherein at least one inner slot 135 is provided on the inner surface 132 of the stator element 131 to receive and guide the multiple projections 125 of the inner rotor portion 120 . The at least one inner slot 135 is adapted to guide the multiple projections 125 and thus move the inner rotor portion 120 axially when the multiple projections 125 are rotated about the central axis A. At the lower end of the stator 130, which faces a chamber of the housing, the stator 130 further comprises an annular element 136. At the bottom of the annular element 136, the annular element 136 is provided with visual indications regarding the axial position of at least one inner slot 135 in a predetermined angular position, and on the opposite top the annular member 136 is adapted to receive the lower end of the outer rotor member 111 in an annular recess 137, as shown in Fig. 1.
    The stator 130 further includes openings 138a, 138b of a locking mechanism and a ratchet mechanism, respectively, extending axially from the lower end of the stator element 131 to allow insertion of a complementary element by a user and extending radially from the inner surface. 132 to allow interaction between the complementary element and the hump surface of the outer rotor member 111. By inserting the locking means 150 into the opening 1384, the locking means 150 interact with the corrugated surface 117 of the outer rotor member 110 to adjust the relative position between the stator 130 and the rotor parts 110, 120. By inserting a ratchet means 60 into the opening 1385, the ratchet means 150 interacts with the wave surface 117 of the outer rotor part 110 to allow rotational movement around the stator 130 and the rotor parts 110 , 120 to be restricted to sen movement in the angular direction with the k lurch with or counterclockwise. The stator element 131 further includes a plurality of recessed or recessed holes 139 on its outer surface to receive a respective screw or the like 170 extending into a respective recessed surface 116 of the outer rotor element 111 about the outer rotor member 110, and thereby also the inner rotor part 120 can be mechanically retained within the annular stator element 131, ie in the space defined by the annular stator element 131 and the lower ring 136. The screw 170 and recesses 118 further restrict the rotational movement of the outer rotor member 110 in the angular direction.
    Next, the operating principle of the display apparatus of the present invention is described. As mentioned above, the valve 10, 100 includes adjusting means and flow control means for controlling the flow or pressure of the air flowing through the valve 10, 100.
    The adjustment means comprises the cup-shaped element 113, optionally attached to the proximal end 21, which is rigidly connected to the outer rotor element 111. By rotating the cup-shaped element 113, the position of the valve 10, 100 depending on the direction of rotation in the direction from the closed position or towards the open position. By rotating the cup-shaped element 113, the outer rotor element 111 rotates in the same direction of rotation and with it the projections 125 of the inner rotor element 121 in the grooves of the outer rotor element 112.
    : BE2021/5028 The projections 125, which protrude through the slots of the outer rotor element 112 and are received in the at least one inner slot 135 of the stator element 131, are passed through the at least one inner slot when the cup-shaped element 113 is rotated. 135 led. Since the at least one inner slot 135 projects in the axial direction À, the axial position of the guide projections 125 with respect to the stator 130 and the bulging rotor member 110 changes. Therefore, the axial position of the annular member 126 of the inner roller member 110 changes. relative to the cup-shaped member 113. This adjusts the flow or pressure of the air flowing through the valve 10, 100 because the air passage through the valve is defined by the space between the cup-shaped member 113 and the annular member 126. The flow rate is increased by rotating the cup-shaped member 113 clockwise and the flow rate is decreased by rotating the cup-shaped member 113 clockwise, or vice versa.
    Other alternatives and equivalent embodiments of the present invention are conceivable within the scope of the invention, as will be apparent to those skilled in the art. The scope of the invention is limited only by the appended claims.
