Definitions

  • the invention relates to a precompression pump for spraying under pressure a liquid, and in particular a cosmetic product such as a hair spray.
  • the invention aims, in particular, to provide a pump of this kind, manually operable and compact, so that it can be housed in the cover of a liquid dispenser cover.

  • the precompression pump of the kind described in EP-A 0 437 131 deserves to be improved from the point of view of spraying precision, since the actuation of this pump is carried out by pressing a button. pusher which at the same time includes the spray nozzle. As a result, the location where the spray is to be applied is difficult to target.
  • this known pump is difficult to assemble.
  • all the constituent parts of this pump are aligned on the same axis of symmetry, its bulk in the axial direction is relatively large, which prohibits its use in many embodiments employing a covering hood.
  • the present invention aims to remedy the drawbacks of the prior art, by providing the user with a dispensing assembly for a liquid of simple construction, the dispensing head of which is fixed and which includes a precompression pump, small footprint and a reduced number of parts, and therefore, from an industrial point of view, is easy to assemble.
  • the pressure drop has been minimized compared to the pump according to EP-A 0 437 131, so that the spray quality is improved. This results in a reduction in the particle size of the liquid leaving the nozzle.
  • the present invention relates to a precompression pump as defined in claim 1.
  • This pump is intended to be mounted on a tank containing the liquid to be dispensed.
  • the first piston is also called the actuating piston, and the second piston, the compression piston.
  • a means can be provided causing the evacuation of the air inside the pump body, disposed between the first and the second pistons.
  • this means is a central pot formed at the top of the second piston, facing the pumping chamber; this stud is able to come into abutment against the first piston, when the operating member is actuated, that is to say, when the volume of the pumping chamber is at a minimum.
  • a mechanical connection is established between the two pistons, the first pushing the second in a position such that the compressed air in the pump body can escape goes to the precompression chamber and the distribution channel.
  • the nozzle is fixed relative to the pump body.

In the pump's rest position, the pin therefore closes the communication between the precompression chamber and the pumping chamber.
  • the pump is actuated, by pushing the operating member against the first elastic return means, the pressure of the liquid which is inside the pump body will rise to a predetermined value and cause this communication, by pushing the precompression member against the second elastic return means. It is clear that the predetermined value of precompression depends on the force developed by this second elastic return means.
  • a means for bringing the reservoir to atmospheric pressure can be provided, constituted, for example, by an air intake orifice pierced in the external wall of the pump body, opening into the lower part of the precompression chamber, that is to say in the part where the second elastic return means is arranged, in order to balance the pressure prevailing in the tank with the external pressure.
  • a sealing means can be arranged between the air intake orifice and the reservoir, closing this orifice during storage period and capable of admitting a dose of air into the reservoir during the distribution of a respective dose of liquid.
  • a first sealing lip of annular shape is carried by the second piston, located in an area between the distribution channel and the air intake orifice.

  • the sliding means for connecting and closing the pump can be constituted by an annular sealing ring, integral with the second piston and facing the first piston, and pressing against an edge or a peripheral groove of the passage between the precompression chamber and the pumping chamber, capable of closing this passage.
  • the first elastic return means housed in the pumping chamber, consists of a helical spring, preferably made of metal.
  • the second elastic return means preferably also consists of a metal helical spring.
