A valve for an aerosol comprises a valve body (1) and a surrounding rubber sleeve (2). The body defines an inlet and outlet passages (3, 4) and bores (5, 6) connecting these passages to the surface of the valve. When the pressure of fluid in the inlet passage (3) and bore (5) builds to a sufficient value the sleeve is pushed away from the body permitting flow through the bores between the passages. When the pressure falls the sleeve closes the bores to interrupt the flow.
L'invention se rapporte à une soupape d'aérosol comprenant un corps de soupape (1) et un manchon en plastique l'entourant (2). Le corps définit des passages (3, 4) d'entrée et de sortie et des alésages (5, 6) reliant ces passages à la surface de la soupape. Lorsque la pression d'un fluide dans le passage (3) d'entrée et dans l'alésage (5) atteint une valeur suffisante, le manchon s'écarte du corps permettant l'écoulement à travers les alésages entre les passages. Lorsque la pression tombe, le manchon bouche les alésages afin d'interrompre l'écoulement.
