Abstract

Described is a valve for retarding pressure transmission in compressed air circuits and having one inlet and at least one outlet. It comprises a movable closure element disposed between the inlet and the outlet and arranged to establish communication between the inlet and outlet under the action of the air pressure supplied from the inlet, and a calibrated elastic system which produces action on the closure element in opposition to the air pressure.
