Definitions
- the present invention relates to a fluid dispensing pump, and more particularly to a new implementation of the actuating rod of the pump.
- a fluid dispensing pump conventionally comprises a pump body in which a piston slidingly connected to an actuating rod.
- This actuating rod slides inside an element generally fixed on the upper edge of the pump body, and which can be a ferrule, a spinner or the like.
- the interface between the actuating rod and the inner surface of the ferrule (or of the element which acts as a ferrule) may or may not be sealed.
- the actuating rod preferably slides tightly inside the shell.
- the object of the present invention is to provide a fluid dispensing pump which does not have the abovementioned drawbacks.
- the present invention aims to provide a fluid dispensing pump which guarantees a perfect seal between the actuating rod and the ferrule, or any similar element cooperating with the actuating rod.
- the present invention aims to provide a fluid dispensing pump which is simple and inexpensive to manufacture and assemble.
- the present invention also aims to provide a fluid dispensing pump which allows actuation of the pump even when the user exerts a force which is not exactly axial on said actuating rod.
- the pump provides a ball joint effect.
- the present invention aims to provide such a ball joint pump which also guarantees sealing between the actuating rod and the ferrule.
- the present invention therefore relates to a pump for dispensing a fluid product
- a pump body in which slides a piston connected in leaktight manner connected to an actuating rod, said actuating rod sliding inside an integral element.
- the pump body such as a ferrule
- said actuating rod comprises a flexible external tubular part in sealed contact with said element and a rigid internal tubular part concentric with said flexible external tubular part, the contact zone between the interior of the ferrule and the actuating rod being sealed in any position of said actuating rod.
- the flexible external tubular part has a first free axial end and a second axial end integral, in particular in one piece, with said actuating rod.
- the two axial ends of the flexible external tubular part are integral, in particular in one piece, with said actuating rod.
- a metering chamber is defined between an inlet valve and an outlet valve, the space between the external tubular part and the internal tubular part of the actuating rod forming part of said metering chamber.
- FIG. 1 is a schematic cross-sectional view of a pump according to a first embodiment of the present invention.
- FIG. 2 is a schematic cross-sectional view of a pump according to a second embodiment of the present invention.
- the pump comprises a pump body 1 inside which a piston 2 actuated in leaktight manner actuated by means of an actuating rod 10.
- the actuating rod 10 is generally connected to an element such as a pusher (not shown) on which the user presses to actuate the pump.
- an element such as a pusher (not shown) on which the user presses to actuate the pump.
- a ferrule 4 On the upper edge of the pump body 1 is mounted a ferrule 4 inside which slides the actuating rod 10. Said ferrule 4 defines in particular the rest position of the piston 2.
- there are pumps in which the actuating rod 10 slides in an element integral with the pump body which is not a ferrule and such an implementation is of course equivalent for the present invention.
- the actuating rod 10 comprises a flexible external tubular part 11 and a rigid internal tubular part 12 concentric with said flexible external tubular part 11.
- the flexible external tubular part 11 comprises a free axial end 13, namely the upper end in the drawing, and a second axial end 14 which is integral with the actuating rod 10.
- this flexible external tubular part 11 is produced in a single piece with the actuating rod 10.
- This implementation makes it possible to obtain a perfect seal between the internal surface of the ferrule 4 and the flexible tubular part 11 of the actuating rod 10, in any position of said actuating rod.
- This implementation also makes it possible to obtain what is called the ball joint effect, that is to say a sealing and a possible actuation of the actuating rod, even when the force exerted on said actuating rod 10 is not exactly axial.
- the flexible external tubular part 11 deforms slightly while allowing movement of the actuating rod and therefore of the piston 2 relative to the pump body 1.
- FIG. 2 there is shown a second embodiment of the present invention, in which the two axial ends 13 and 14 of the flexible tubular external part 11 are integral with the actuating rod, in particular they are produced in one piece with it.
- the external tubular part 11 is less flexible than in the first embodiment of Figure 1, but still provides a good seal and a certain ball joint effect.
- An advantage of this second embodiment resides in the space 1S existing between the external and internal tabular parts 11, 12 of the actuating rod.
- this space 18 advantageously forms part of the metering chamber 20 of the pump, which is defined between the inlet valve 21 and the outlet valve 22 of the pump.
- Figures 1 and 2 show particular embodiments of the pump, in particular the inlet and outlet valves 21, 22 and therefore the metering chamber. It is understood that the present invention applies to any type of pump and is not limited to these embodiments used by way of example.
- the present invention applies to any type of pump, and it is particularly advantageous in an air return pump as shown in the drawings.
- a vent hole is provided in the fluid dispensing device, that is to say either in the reservoir, in the pump, or in the fixing ring. of the pump on the tank.
- an appropriate filter is provided at the vent hole.
- the filter is arranged between the ferrule 4 and the fixing ring 30 of the pump on the reservoir (not shown). This filter 40 therefore filters the air from the venting passage. It is in this type of essential device that all of the air entering the interior of the tank passes through the filter.
- the air passage is designated diagrammatically by the reference numeral 50 and extends from the outside between the fixing ring 30 and the ferrule 4, then through the filter 40 , then between the outside of the shell 4 and the inside of the pump body 1, finally leading to the inside of the tank through an orifice 50 provided in the pump body by the piston 2. As visible in the figures , this orifice 50 is closed in the rest position of the pump by the piston 2.
- the orifice 50 of the pump body is closed by the piston 2 in the pump rest position, and the filter is isolated from the interior of the reservoir by a neck seal 60 which is mounted between the fixing ring 30, the pump body 1 and the reservoir (not shown).
- the neck seal 60 is tightly mounted around the pump body 1, thus preventing any contact between the product and the filter 40.
