Abstract: A manual pump (P) having a pump body (B) defining a slide cylinder (F) for a piston (K) secured to an actuator rod (S); a pump chamber (C) and an outlet valve (V) arranged between the pump chamber (C) and a dispenser orifice (O) so as to dispense the fluid from the pump chamber (C). The pump includes an inlet valve (2, 12) arranged between the pump chamber (C) and an inlet (I) of the pump (P) to take the fluid into the pump chamber (C) from the reservoir (R), the inlet valve having a movable member (2) that selectively bears against a valve seat (12), a return passage (23) enabling a fraction of the fluid that is put under pressure in the pump chamber (C) to escape therefrom without passing via the outlet valve (V). The return passage (23) creates a lack of sealing at the inlet valve.

Abstract: A fluid dispenser comprising a fluid reservoir (1), a pump (2) that is mounted on the fluid reservoir (1), and a pushbutton that is mounted on the pump (2) so as to actuate it; the fluid dispenser being characterized in that the pushbutton comprises a base (3) that is mounted in stationary manner on the pump (2), and a grip member (4) that is mounted in removable manner on the base (3), the grip member (4) including a fluid applicator (47), the grip member (4) defining a bearing surface (S) which may be pressed axially so as to move the base (3) and thus actuate the pump (2) so as to load the applicator (47) with fluid.
