Abstract

A pneumatic booster operated by a plunger () housed in a bore () and bearing on a moving seat () which co-operates selectively with a shut-off member (). The shut-off member () is capable of selective co-operating with a stationary seat (). The plunger () being characterized by a cylindrical body () and a ring (). The ring () sliding between a front stop () and a rear stop () on the cylindrical body (). A front section of the ring () being located between the cylindrical body () and the bore () while a rear section () is designed to bear against the moving seat (). The ring () being temporarily retained in a stationary position in the bore () independent of any movement of the cylindrical body () through the action of a pivoting key () and an elastic snap ring () to allow permit and extended actuation of the booster after a sharp braking action has occurred.
