Abstract
The invention concerns a dispensing device comprising a fluid product pump (1) defining: a pump chamber (112) with variable volume; an intake valve (14) allowing the fluid product to penetrate into the pump chamber; and an outlet valve (16) allowing the pressurized fluid to exit from the chamber; a dispensing orifice (195) downstream the outlet valve, and the outlet valve comprising a valve seat (126) and a mobile valve member (16) elastically stressed on said seat. The invention is characterized in that the mobile valve member (16) forms piston means for delivering the fluid product downstream towards the dispensing orifice.
