ABSTRACT:
A dispenser for dispensing atomized fluids under pressure and provided with a shut-off element operated by the pressurized fluid. The dispenser includes a compression chamber housing a movable piston from which there projects an appendix which, when in a rest state, is urged by a spring to seal a discharge hole provided in a body closing the chamber, which communicates with a seat into which the end of the stem of a pressurized fluid pump can be inserted. When the fluid pressure within the chamber overcomes the resistance of the spring, the piston moves and the appendix frees the discharge hole. That end of the piston close to the appendix is slidable in a sealed manner within a cavity in a bush and a communication duct between the compression chamber and the discharge hole is freed only when the end of the piston emerges from the bush cavity on withdrawing.
