摘要

The pump (1) has a suction valve (7) and an expulsion valve (8) at input and output of the pump, respectively. A metering chamber (6) is slidingly mounted on the suction valve and fixed on a hollow tube (13) communicating with an interior of a flask (2). The expulsion valve is mounted at an end of a nozzle tip at the output to constitute an extreme closing. A cylindrical ring limits movement of a valve lifter. An Independent claim is also included for a device for conditioning and distributing fluid products.
