Abstract: A pump comprising a tubular body delimiting internally a metering chamber and comprising an inlet orifice, an inlet valve, a stem mounted so as to be able to move inside the body and comprising an actuation tube delimiting an outlet duct, an insert assembled to the actuation tube and comprising a base placed inside the metering chamber and facing the inlet orifice, and a discharge orifice, an annular piston mounted so as to slide inside the body and on the stem, the piston and the base comprising annular surfaces suitable for forming a discharge valve, a ball-and-socket joint being arranged between the insert and the actuation tube.

Abstract: Pump for dispensing a dose of a fluid product, comprising a tubular body including an intake orifice; an end member associated with the body and including a rest abutment and an end-of-stroke abutment; a compression member mounted so as to move inside the body between a rest position in which said compression member is in abutment against the rest abutment, and an end-of-stroke position in which said compression member is in abutment against the end-of-stroke abutment, said compression member being elastically returned toward the rest position and including an exhaust orifice; a metering chamber; and an intake valve and an exhaust valve adapted to selectively close off the intake orifice and the exhaust orifice, respectively.

Abstract: The invention concerns a dispenser of doses of pasty or gel-type product comprising a body and means for delivering the product without air intake, the delivery means including an elastic return compression element and a closing sliding element mounted in the body to delimit a chamber for compressing the product, the body including a tubular outer side wall forming a sheath and enclosing a generally cylindrical inner side wall forming a reservoir, the sheath and the reservoir being arranged along a common axis, the reservoir having a circular envelope about the axis, the compression element and the closure element being mounted at least partly inside the reservoir, the dispenser comprising means for assembling the reservoir and the sheath and means for radially locking the reservoir inside the sheath.
