Definitions

  • the present invention relates to a fluid dispenser pump generally intended to be associated with a fluid reservoir to form together a fluid dispenser. It is a dispensing member whose actuation is usually performed manually using a finger of the user.
  • the fluid product is distributed in the form of a jet of fine sprayed droplets, a continuous net or a dab of fluid, particularly in the case of viscous product, such as cosmetic creams.

  • the dispensing member comprises a pusher forming not only a dispensing orifice but also defining a portion of a fluid product chamber in which fluid is selectively pressurized.
  • a pump it is a pump chamber.
  • a peculiarity of this pusher pump lies in the fact that an inner surface of the pusher, of generally cylindrical general shape, serves as a sealed sliding shaft for a piston which moves in sealed contact in this barrel to thus selectively unmask the orifice of distribution.
  • This piston is generally a piston of the differential type that moves in response to a pressure variation of the fluid within the chamber.
  • This differential piston is to be differentiated from the main piston whose displacement is generated by the actuation of the pusher.

  • the main drum for the main piston can also be formed by the pusher.
  • the pusher comprises a bearing wall on which is exerted a pressure with a finger to actuate the pusher.

  • the differential piston is dissociated from the main piston.
  • the differential piston is biased away from the support wall by a spring which acts as both a return spring and a precompression spring.
  • the sliding piston of the differential piston is formed with an outlet conduit which leads to a nozzle attached in a housing formed in the skirt of the pusher.
  • This nozzle forms a dispensing orifice at which the fluid product exits the dispensing member.
  • the housing formed by the skirt is made with a swirl system that cooperates with the nozzle to drive the fluid in a swirling motion before exiting through the dispensing orifice.
  • This vortex system is conventionally formed by one or more tangential swirl channels opening into a vortex chamber centered precisely on the dispensing orifice.
  • the swirl system is in the form of a recess network within the skirt housing. This recess network is then supplemented by the attached nozzle which isolates the swirl channels and the chamber.
  • the sliding shaft of the differential piston is in the form of a cylindrical surface only interrupted at the outlet channel.

  • the inlet valve of the chamber is formed by a valve deformable flap that deforms when the chamber is in depression. This valve is formed by an insert on the body.
  • the object of the present invention is to improve the pump of the document US-4,050,613 by reducing the number of component parts and optimizing the overall operation of the pump.
  • the present invention provides a pump having the features of claim 1, and in particular a differential piston formed integrally with a movable inlet valve member, which cooperates with an inlet valve seat.
  • the inlet valve is formed by a ball or flap resting on a seat.
  • the movable inlet valve member is formed with the differential piston because the latter moves away from the support wall when the pressure increases in the pump chamber. This contributes to the movable inlet valve member moving toward the inlet valve seat.
  • the support wall forms a wall element of the pump chamber.
  • the space formed between the differential piston and the support wall is a dead space that does not perform any function.
  • the differential piston comprises at least one fluid-through hole.

  • the spindle Since the swirl system extends to form a recessed portion in the sliding piston of the differential piston, the spindle must form a negative impression. corresponding which protrudes outward. Also, when removing the pin during demolding, the protruding footprint must be removed in force.

Since the plastic is flowable, the passage of force of the protruding imprint marks very little sliding shaft. This is not excluded, however.

  • An interesting feature of the invention lies in the fact that the piston member 140 is urged against the bearing wall 121 and moves under the effect of the increase in pressure inside the pump chamber. away from this support wall. This is made possible thanks to the fluid passage holes 134 which pass through the plate 131 forming the differential piston. It can also be said that the support wall defines a wall element of the pump chamber.

  • the return spring and precompression is integrally formed by the body 210 and has the reference numeral 2171.
  • the spring extends in the extension of the main shaft 217 and bears under the plate 231 which forms the differential piston with its two lips 232 and 233.
  • the spring 2171 thus extends concentrically around the ring 230 which forms the main piston 236.
  • the dispensing member 200 of the figure 4a can be identical to that of figures 1 and 2 .
  • the dispensing member 300 comprises a return spring 3311 which is integrally formed by the piston member 330. Specifically, the spring 3311 extends from the underside of the tray 331. It bears at its lower end on the shoulder 3331 formed by the body 310. Apart from the particular shape of the spring, the dispensing member 300 may be identical to that of the figures 1 and 2 .
  • the dispensing member comprises only three components, namely a body, a pusher and a piston member, the return spring and precompression being integrated either to the body or to the piston member.
