Abstract
A pump for dispensing fluid products includes a pump body, a pump chamber, at least one piston sliding inside the pump chamber for dispensing a fluid product, a dispensing orifice, and a shutter which interacts with the dispensing orifice and is embodied in such a way that it is movable and/or deformable between the closed position of the dispensing orifice and the open position thereof, the shutter being elastically driven to a closed position. The pump includes only one elastic element in the form of a spring for bringing at least one piston to a rest position after actuation and for driving the shutter to a closed position and the at least one piston is embodied in one piece with the shutter.
