Definitions
- the present invention relates to a liquid dispensing device comprising a nozzle whose displacement is driven by a piston, and incorporating a non-return valve function.
- a telescopic nozzle system for a motor vehicle.
- This nozzle consists of a cylinder containing pressurized windshield washer fluid which exerts a thrust on a piston connected to the nozzle of the nozzle which rises so as to position it vis-à-vis the windshield.
- the washer fluid circulates in a passage through the piston and pushes a ball closing a hole to enter the nozzle head to be projected on the windshield.
- a conventional non-return valve is placed in the conduit of the axis of the piston to ensure the lifting of the nozzle of the nozzle and put the conduits for supplying the washing liquid in correspondence to ensure the projection of the washing liquid on the surface to be cleaned.
- a conventional non-return valve is simply placed between two pipe sections, so as to avoid the return of the fluid to the washing tank and to avoid an impulse too long for a next cycle of washing.
- the invention proposes, in view, to reduce the number of parts, and to simplify the assembly of the supply ducts, not simply to remove the check valve, but to make this function return valve by a piece already existing, namely in this case the piston itself through its cooperation with the room in which it slides.
- the invention has developed a liquid dispensing device, preferably washing liquid, the piston acting as the non-return valve so as to maintain the liquid level as close to the nozzle and thus dice the washing control pulse, the washing liquid sprung from the nozzle.
- the present invention relates to a liquid dispensing device, comprising a piston movable in a chamber and a nozzle connected to the piston so that the movement of the piston causes a displacement of the nozzle one end of the piston cooperating with the chamber to form a non-return valve.
- the lower end of the piston has a convex shape, advantageously spherical.
- the nozzle is fixed relative to the piston.
- the piston is in one piece.
- the body of the piston through which the washing liquid penetrates to a frustoconical shape and that the sealing of the spherical portion of the piston on the frustoconical portion of the body (4) is made on a circular line.
- the chamber consists of a tubular piece closed by two plugs.
- the piston is provided with a seal, above the spherical cap portion.
- the piston does not include a seal at the end of the piston.
- the supply duct attached to the lower end of the body is bent and in that the piston does not go down to the elbow.
- FIG. 1 is a plan view schematically showing a device comprising a non-return valve in closed position according to the invention.
- FIG. 2 is a plan view schematically showing a device having a check valve ⁇ back in the open position according to the invention.
- Figure 1 is a plan view schematically showing a device 1 comprising a non-return valve 2 in closed position according to the invention.
- the device 1 is a telescope comprising a piston 3 and a body 4.
- the body 4 is a tubular piece 4d closed by two plugs 4a, 4b at each of its ends.
- the piston 3 having at its upper end a nozzle 5 and at its lower end a spherical cap 6.
- the piston 3 is directed downwards by the action of a compression spring 7 resting on the bottom of the upper cap 4a of closing the body 4 and on a shoulder 3a of the rod 3b of the piston 3.
- the lower end of the piston 3 comprises above the spherical cap 6 two transverse orifices 3c opening into an axial conduit 3d of the piston 3 for feeding washing liquid nozzle 5 placed at the upper end of the piston 3.
- orifices 3c the piston 3 is provided with a gasket 8 placed in a circular groove 3e.
- This seal 3 e avoids the washing liquid to enter the circular space 9 where the compression spring 7.
- the lower closure cap 4b of the body 4 comprises axially a through opening 4c on which is screwed a conduit 10 provided with a shoulder resting on the stopper 4b.
- the conduit 10 is bent at right angles.
- the washing liquid 16 enters the conduit 10 along the arrow 17.
- the circular opening of the body 4 opens into the body 4 by a flared portion 4c of substantially frustoconical shape forming a receptacle of the end of the cap spherical 6 piston 3.
- the sealing is performed in this case on a circular line 20.
- the flared portion 4c may be cylindro-spherical. In this way the sealing is performed on a surface.
- the piston 3 in operation can have a movement only along its axis.
- a pin screw 11 is screwed into the upper plug 4a, the pin 12 opening into a groove 13 formed on the periphery of the piston 3 along its longitudinal axis.
- the groove 13 is helical, therefore, the nozzle 5 in operation, during the projection of the liquid moves in a helical path.
- FIG. 2 is a plan view schematically showing a device 1 comprising a non-return valve 2 in the open position according to the invention, that is to say in the operating position substantially halfway through the helical groove 13, considering the position of the stud 12 of the screw 11 located between the beginning 13a of the groove 13, visible on the rod extracted from the piston 3 and the end 13b of the groove 13 visible on the inner rod of the piston 3.
- the liquid enters the body 4 through the flared orifice 4c which under the pressure of the liquid 16 along the arrow 18 pushes the piston 3 upwards against the force exerted by the compression spring 7. Simultaneously, the liquid enters through the two orifices 3c in the axial conduit 3d of the piston 3 to the nozzle 5 where it is projected along the arrow 19 on the surface to be cleaned.
- the movement of the piston mechanically drives, therefore directly, the displacement of the nozzle.
