    DESCRIPTION

    Tank filling tap.

    OBJECT OF THE INVENTION 5

    The present invention, as expressed in the statement of this specification, refers to a tank filling tap that has a fluid inlet in which a valve device that adopts a closed position and an open position is inserted, so that as the tank is filling the valve device gradually closes the flow of fluid by the action of a buoy that suffers the thrust of the fluid from the tank as it is filled, transmitting the movement of the buoy to the valve device through an intermediate mechanism.

    Starting from this premise, the invention focuses on characteristic means for fixing the buoy to quickly and effectively regulate its height positioning according to the filling volume of the tank that the user desires.

    The invention also focuses on the intermediate mechanism that associates the buoy with the valve device, so that this intermediate mechanism causes an effective and practical axial displacement of a pusher piston associated with the valve device.

    BACKGROUND OF THE INVENTION

    At present, numerous taps are known for filling tanks that generally comprise a water inlet where a valve device is inserted that allows or not the passage of water into the interior space of the tank, so that the valve device is associated with a buoy that rises and falls according to the height of the water level inside the cistern, so that once the desired water level is reached inside the cistern, the valve device closes interrupting the passage of water inside of the cistern. 30

    In some cisterns, the buoy is attached to one end of a rod that is connected by the end section opposite to the valve device to seal or release the passage of water into the cistern.
     35
    Other more modern buoys are coupled around a vertical guide with height adjustment to be able to place it in the desired position according to the level of water height inside the cistern. In these cases, the height adjustment of the buoy is carried out by means of a threaded rod coupled to the buoy, so that the rotation of the threaded rod drags the buoy up or down. 40

    The patents with publication number ES 2239877 and ES 2353475 refer to taps for filling tanks where the buoy is coupled around a vertical guide, so that the buoy has height adjustment by means of a threaded rod.
     Four. Five
    In this situation, turning this threaded rod in one direction or another is achieved by placing the buoy at the height required to fill the tank with a greater or lesser volume of water.

    The threaded rod is in turn associated with the valve device, so that as the tank is filled with water, the buoy undergoes an upward thrust that is transmitted to the valve device that gradually closes the water passage until completely sealed.

    DESCRIPTION OF THE INVENTION

    In order to achieve the objectives and avoid the inconveniences, the invention proposes a tank filling tap comprising a hollow head within which a valve device associated with a buoy is located by means of an intermediate device, 5 further comprising a vertical tube attached to the hollow head, where the vertical tube is located inside a central passage of the buoy that moves up and down according to the rise and fall of the water level of the tank.

    The buoy is connected to a bushing coaxially coupled around the vertical tube, along which the bushing moves axially and freely, where the mobility of the buoy up and down drags the bushing when the buoy is anchored to the bushing.

    The central passage of the buoy has internal axial retention reliefs that complement and interact with projections integral to the bushing as a means of anchoring the buoy to the bushing when the internal reliefs and the projections are aligned and in contact with each other.

    The buoy has relative rotational movement with respect to the bush limited by corresponding longitudinal stops, so that the rotation of the buoy in one direction or another 20 releases the axial interlock of the buoy being free to be able to position it at the required height in the position of interlocking The bushing has free axial mobility and blockage of its rotation with respect to the vertical tube.

    Said bushing further comprises parallel skates. The bushing is displaced and guided vertically in pipes arranged along the vertical tube; the parallel skates being linked to a rocker arm that is coupled to the hollow head by means of an articulated connection.

    In proximity to the articulated connection, it connects one end of a connecting rod by means of an anterior articulated connection, while an opposite end of the connecting rod connects to a pusher piston by means of a rear articulated connection, the pusher piston being associated with the valve device.

    In this situation, the swinging in one direction of the rocker axially moves the pusher piston 35 against the valve device towards a closed position during the filling of the tank, while the swinging in the opposite direction of the rocker due to the descent of the buoy by gravity releases the passage of fluid through the valve device.

    The rocker arm comprises a front fork and a double rear extension that is coupled 40 at its free end to a part of the hollow head by means of the articulated connection, while in said double rear extension a connecting rod is also coupled by its previous articulated connection.

    Extreme sections of the fork have opposite pins fitted and guided in two grooves of the parallel skates of the coupled and guided bushing in the pipes arranged along the vertical tube attached to the hollow head. The parallel skates are located at the top of the bushing.
    The rear articulated connection of the connecting rod is a spherical joint, while the anterior articulated connection of the connecting rod comprises bolts embedded in holes of 50 the double extension that forms part of the rocker arm.

    On the other hand, the rotation of the buoy is limited by longitudinal stops that start from the internal surface of the central passage of the buoy.

    The new buoy height adjustment system in combination with the intermediate device that basically covers the rocker arm and bushing, achieves a small tap size for filling and optimum operation.
     5
    This space reduction is very important to adapt the faucet assembly and install it easily in tank designs with shapes that seriously impair the assembly of the interior mechanisms.

    Next, in order to facilitate a better understanding of this specification, and forming an integral part thereof, a series of figures are attached in which the object of the invention has been illustrated and not limited to.

    It comprises a hollow head (1) within which a valve device (2) associated with a buoy (3) is located by means of an intermediate device, so that as the tank is filled with water that passes through the Valve device (2), the water that fills the tank itself pushes the buoy (3) upwards, whose displacement is transmitted to the valve device (2) that progressively closes the water passage until the passage is definitively interrupted of water.

    When the tank is discharged, the buoy (3) descends downwards releasing the passage of water through the valve device (2), so that again as the tank is filled, the water passage is closed according to It has been described in the previous paragraph.

    Describing in more detail the tap of the invention, the valve device (2) is operated by means of a thrust plunger (4) with axial displacement that is associated with a rocker arm (5) with interposition of a connecting rod (14). 25

     The rocker arm comprises a front fork (5a) and a double rear extension (5b) that is coupled at its free end to a part of the hollow head (1) by means of an articulated connection (6), while some end sections of the fork ( 5a) they have facing studs (7) fitted and guided in two grooves (8) of parallel skates (9) 30 integral with a bushing (12) coupled around a vertical tube (11) attached to the hollow head (1).

    The bushing (12) is guided and displaced vertically in pipes (10) arranged along the vertical tube (11). 35

    Thus, around said vertical tube (11) a bushing (12) is freely coupled where the buoy (3) is coaxially coupled. For this, the buoy (3) has a central passage (13) coupled around the bushing (12), so that the buoy (3) can be fixed to the bushing (12) at different heights according to the volume of water that is want to contain inside the cistern. 40 Therefore, the positioning of the buoy (3) will condition the water level of the tank, so that at a lower height it will close the valve device (2) with a low level of water inside the tank.

    The central passage (13) of the buoy (3) has diametrically opposite internal reliefs (13a) 45 that narrow said central passage (13) and that complement and interact with projections (12a) integral with the bushing (12), of so that when turning the buoy (3) in one direction or another, the axial interlock of the buoy (3) is free to be able to raise it down to the desired height, so that once the expected height is determined, it is rotated again the buoy (3) in the opposite direction towards the blocking position where the internal reliefs (13a) of the central passage (13) and the projections (12a) of the bushing (12) are in contact and interacting with each other.

    The rotation of the buoy (3) is limited by longitudinal stops (15) that start from the
    internal surface of the central passage (13) of the buoy (3).

    In proximity to the articulated connection (6) of the double rear extension (5b) there is a corresponding anterior articulated connection (14a) with one end of a connecting rod (14), which connects at its opposite end with the pusher piston (4) by means of a rear articulated connection 5 (14b), so that as the tank is filled, the buoy (3) ascends by dragging with it to the bushing assembly (12) and parallel skates (9), through whose grooves (8 ) slide and guide the facing lugs (7) of the fork (5a) belonging to the rocker arm (5).
     10
    The rear articulated connection (14b) of the connecting rod (14) is a spherical joint, while the anterior articulated connection (14a) of the connecting rod (14) comprises studs (16) embedded in holes (17) of the double extension (5b) that is part of the rocker arm (5).

    The rise of the buoy (3) also generates the rotation of the rocker (5) around its articulated connection 15 (6), this operation in which the central portion (14) of the double extension (5b) axially displaces the pusher pin (4) in the sense of closing the valve device (2) until the tank is filled to the required level, at which time the water passage is closed by closing the valve device (2).
     twenty
    Once the cistern is unloaded, the operating process is reversed, that is, the buoy (4) descends by dragging with it to the bushing assembly (12) and parallel skates (9), descending by gravity. This descent in turn drags the rocker arm (5) that will swing in the opposite direction to that described during the filling of the tank, thereby releasing the axial thrust on the pusher piston (4) that will move outwards releasing the valve device 25 (2) that will allow the passage of water through it again.

    It should be noted that the distance between the articulated connection (6) of the rocker arm (5) and the previous articulated connection (14a) is greatly reduced and is reduced as the buoy rises, achieving a powerful thrust torque, as shown in figures 6 and 7; whereby the axial force transmitted to the pusher piston (4) is elevated during the rotation of the rocker arm (5) driven by the rise of the buoy (4), driven in turn by the rise in water level within the tank.
