Abstract
The valve has a piston which slides in a chamber (2) when operated by a pusher (16) and returns under the action of a spring (14). The piston is made in a single piece and has peripheral grooves in which seals (5, 11) are freely positioned. The piston has a head (1) whose diameter corresponds to that of the chamber (2) and a reduced diameter portion (3) between which is a groove to receive the lipped seal (5). Portion (3) is connected to the stem (6) by a small diameter portion providing a groove for the seal (11).
