The 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 pump body () is embodied in one piece with the shutter ().

Pump for dispensing fluid products

A manually actuated fluid dispenser pump having a pump body (), a piston () mounted to slide in leaktight manner in the pump body () between a rest position and an actuating position, an actuating rod () connected, preferably integrally, to the piston (), and a ferrule () fixed to the top edge () of the pump body () to define the rest position for the piston (). The actuating rod () is mounted to slide in the ferrule (). The ferrule () is provided with at least one internal sealing lip () co-operating in leaktight manner with the actuating rod ().
