Abstract (en)
[origin: FR2795779A1] The invention concerns a pre-compression spray pump for dispensing measured amounts of a fluid product, comprising a piston (1) integral with an actuating rod (2) and sliding in a pump body (3) comprising a pump chamber (10) defined between an intake valve (11) and an outlet valve (12). The invention is characterised in that when the pump is actuated, the outlet valve (12) is urged towards its closing position by the pressure of the product contained in the pump chamber (10), and when the pump ceases to be actuated, a lever element (30) moves said outlet valve (12) towards its opening position to enable the product contained in the pump chamber (10) to be expelled.
