Abstract

A pneumatic tool has a control valve with a cup-shaped elastomeric valving element disposed in a socket to cover a channel leading from the socket. The forward end of an air inlet forms the socket. The peripheral wall of the elastomeric element can be deformed by means of a radial rod to form between the elastomeric element and the socket a passage from the inlet to the channel.
