Definitions

  • the present invention relates to a pump for dispensing metered quantities of fluid, and more particularly to a precompression pump in which the dispensing of the product is carried out independently of the actuation speed exerted on the pump by the user.
  • the outlet valve of the pump chamber must ensure that the pump chamber is sealed completely during the entire operating stroke of the pump, and open only when the pump chamber is closed. at the very end of actuation of said pump to allow the expulsion of the product.
  • this outlet valve is made in the form of an elastically deformable sleeve disposed between the pump body and the movable actuating rod of the pump. This valve must be rigid enough not to deform during actuation of the pump under the effect of the pressure created in the pump chamber. Its opening by elastic deformation is performed at the end of actuation using a shoulder formed in the pump body.
  • This type of outlet valve has the disadvantage that it must be both rigid enough not to deform before the end of the stroke of the pump, and sufficiently deformable for, at the end of actuation, to deform without effort exaggerated under the effect of a mechanical cam. A satisfactory balance between these two conflicting requirements is difficult to find and the reliable operation of the pump can be altered by said outlet valve. In particular, the least differences in size or stiffness due to manufacturing tolerances of the outlet valve can cause such a malfunction.
  • WO 01/02100 discloses a pump in which the outlet valve is opened by means of a lever which slides in the pump body, an internal shoulder of said pump body causing the tilting of said lever which thereby displaces the outlet valve to open it .

  • said outlet valve element is made in one piece with said piston.
  • said piston comprises an upper lip and a lower lip, said upper and lower lips sealingly sliding in said pump body during actuation of the pump, said outlet valve element being formed by said lower lip of said piston, so that in actuating position, said lower lip does not cooperate sealingly with said pump body, thereby opening said outlet valve.
  • a lateral passage is formed in the piston between said upper and lower lips.
  • said actuating rod comprises an outer shoulder to form the stop defining the actuating position of the pump.

  • the invention is not limited to these advantageous achievements of the inlet valve.
  • the outlet valve 12 comprises an outlet valve element 39, 35 and is designed in such a way that, when the pump is actuated, it is only open at the end of actuation of the pump in order to allow the pump to open. expulsion of the product contained in the pump chamber.
  • This opening is made, according to the invention, at the level of means of passage 40, visible in particular on the figure 4a .
  • These passage means 40 are preferably formed at a radial inner shoulder 4 of the pump body.
  • These passage means 40 comprise at least a portion of pump body of greater diameter in which the outlet valve member 39, 35 will no longer cooperate sealingly with said pump body.

  • the inlet valve member 10 can cooperate with a spring 20 which, upon actuation of the pump, is compressed by the displacement of the inlet valve member 10 under the effect of the pressure created in the pump chamber.
  • said spring 20 of the inlet valve 11 may also act as a return spring of the pump, thus bringing the piston 1 to its rest position after expulsion of the product.
  • the operation of the pump may be as follows: in the rest position of the pump, represented in particular on the figures 1 , 5 and 7 to 9 , the inlet valve member 10 is urged towards its open position by the spring 20.
  • the piston 1 slides axially downwards in the pump body 3 and the element of inlet valve 10 is urged axially downwards (in the orientation of the device shown in the figures), thus closing the inlet valve 11, as shown in FIG. figure 2 .
  • the inlet valve element 10 is displaced by the pressure of the product contained in the pump chamber by compressing the spring 20.
  • the outlet valve 12 will open when the outlet valve member 39, 35 arrives at the passage means 40 of the pump body, which suddenly releases the pressure of the pump chamber, the spring 20 reducing and the inlet valve member 10 to its starting position by expelling the product contained in the pump chamber.
  • the reliability of the pump according to the invention is improved because the outlet valve 12 is not likely to open before the end of the actuating stroke of the pump. This also simplifies the priming of the pump, the air contained in the pump chamber before the first actuating the pump that can escape from the pump chamber during said first actuation by the same path as the dose expulsion during subsequent actuations.
  • the inlet valve member 10 cooperates with the outlet valve member 39, 35 at the end of the dose expulsion and throughout the return stroke of the pump to its rest position, by pressing said outlet valve 39, 35 against said pump body.
