<p>The invention relates to a fluid product dispensing member which is intended to be connected to a fluid product tank (50). The inventive dispensing member consists of: a chamber (1) in which the fluid product is pressurised, said chamber comprising an inlet check valve (161, 38) and an outlet; a dispensing port (25); a main piston (133) which is in sealed sliding contact in a main barrel (242), such that the volume of the chamber can be varied; a push rod (20) which can be actuated in order to generate a relative movement between the main piston and the main barrel; and a differential piston (31, 32, 33) which is in sealed sliding contact in the push rod in order selectively to uncover the outlet of the chamber. The invention is characterised in that it also comprises stroke-limiting means (28, 39) for limiting the stroke of the differential piston in the push rod, said limiting means being provided between the push rod and the differential piston.</p> |
