ABSTRACT:
A pushbutton for a fluid dispenser includes a chamber 39 provided with three outlet orifices 5, and at least one cylindrical cavity 24 having an axis of symmetry 2. A piston 31 secured to three outlet closures is slidably received in the cylindrical cavity, and is urged by spring 37 to cause the three closures to seat and seal against the orifices. The piston is pushed back by the pressure of the fluid substance emitted by a dispenser to open the orifices, and is extended towards the outlet orifices by a rod 32 having a degree of flexibility. The closures are constituted by three valve pins 35 secured to the rod, each having a tip 36; 36' configured to close one of the orifices.
