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 dispenser pump conventionally comprises a pump body in which a piston connected to an actuating rod is sealingly slid.
  • This actuating rod slides inside an element generally fixed on the upper edge of the pump body, and which may be a shell, a turret or the like.
  • the interface between the actuating rod and the inner surface of the ferrule (or the element which acts as a ferrule) can be sealed or not.
  • the actuating rod preferably slides in a sealed manner inside the shell.
  • the present invention aims to provide a fluid dispensing pump that does not reproduce the aforementioned drawbacks.
  • the present invention aims to provide a fluid dispensing pump which ensures 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 dispenser pump that is simple and inexpensive to manufacture and assemble.
  • the pump provides a ball joint effect.
  • the object of the present invention is to provide such a ball-and-socket pump which also guarantees the seal between the actuating rod and the ferrule.
  • the present invention therefore relates to a fluid dispenser pump as described in claim 1.
  • Advantageous embodiments are described in the dependent claims.
  • the present invention also relates to a fluid dispenser device comprising a pump as defined above.
  • the pump comprises a pump body 1 within which a piston 2 actuated by means of an actuating rod 10 seals tightly.
  • 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.
  • a shell 4 On the upper edge of the pump body 1 is mounted a shell 4 inside which slides the actuating rod 10. Said ring 4 defines in particular the rest position of the piston 2.
  • the actuating rod 10 slides in a member 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 outer tubular portion 11 and a rigid inner tubular portion 12 concentric with said flexible outer tubular portion 11.
  • the flexible outer tubular portion 11 has 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 outer tubular portion 11 is made integrally with the actuating rod 10.
  • This implementation makes it possible to obtain a perfect seal between the inner surface of the ferrule 4 and the flexible tubular portion 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 seal and a possible actuation of the actuating rod, even when the force exerted on said actuating rod 10 is not exactly axial. Indeed, in this case, the flexible outer tubular portion 11 is slightly deformed while allowing movement of the actuating rod and therefore the piston 2 relative to the pump body 1.
  • FIG. 2 there is shown a second embodiment of the present invention, wherein the two axial ends 13 and 14 of the flexible tubular outer portion 11 are integral with the actuating rod, in particular they are made in a monoblock manner with the this.
  • the outer tubular portion 11 is less flexible than in the first embodiment of the figure 1 , but still provides a good seal and some ball joint effect.
  • An advantage of this second embodiment lies in the space 18 existing between the outer and inner tubular portions 11, 12 of the actuating rod. Indeed, as visible on the figure 2 this space 18 is advantageously 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.
  • FIG. 1 and 2 represent particular embodiments of the pump, in particular inlet and outlet valves 21, 22 and therefore of 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 is particularly advantageous in a return air pump as shown in the drawings.
  • a vent hole is provided in the fluid dispensing device, that is to say either in the tank, in the pump, or in the fixing ring. pump on the tank.
  • an appropriate filter is provided at the vent hole.
  • the filter is disposed between the ferrule 4 and the fixing ring 30 of the pump on the reservoir (not shown). This filter 40 thus filters the air of the vent passage. It is in this type of essential device that all the air entering the tank passes through the filter.
  • the air passage is designated schematically by the numeral 50 and extends from the outside between the fixing ring 30 and the ferrule 4, then through the filter 40, and between the outside of the ferrule 4 and the inside of the pump body 1, to finally open into the tank through an orifice 50 provided in the pump body by the piston 2.
  • this orifice 50 is closed in the position of This has a particularly advantageous effect for a large number of applications, in which the product contained inside the tank must in no case come into contact with the filter, which could lead to contamination of the product.
  • the orifice 50 of the pump body is closed by the piston 2 in the rest position of the pump, and the filter is insulated from the interior of the tank by a neck seal 60 which is mounted between the fixing ring 30, the pump body 1 and the tank (not shown).
  • the neck seal 60 is sealingly mounted around the pump body 1, thus preventing any contact between the product and the filter 40.
