Definitions

  • the invention relates to a pump for dispensing a fluid product.
  • Such an embodiment of the two-piece nozzle assembled, namely the insert and the actuating tube, is intended to allow the mounting of the piston on the nozzle, for example when said nozzle is provided with shoulders facing the base, particularly for limit the stroke of the piston or to form a seat for a resilient member adapted to recall the nozzle in position FR 2 792 553 describes a dispensing pump with a nozzle and a piston.
  • the insert is rigidly connected to the actuating tube, by press fitting or otherwise.
  • the known pump has problems of sealing and piston wear. Indeed, such a pump may have an angular offset between the insert and the actuating tube. Therefore, the piston can not exert a distributed support inside the body which impairs the seal and increases the risk of premature wear of the piston. And the annular bearings of the base and the piston can not come in contact in a uniform manner. This results in a lack of sealing of the exhaust valve and a risk of wear of the piston seats.

This arrangement then improves the sealing of the piston and the exhaust valve and limit wear.
  • the realization of the swiveling between the insert and the actuating tube improves the capacity of the pump in terms of fluid distribution and priming, when the displacement the nozzle aims to expel the air initially contained upstream of the exhaust valve, in particular in the metering chamber, to replace it with fluid.
