Adjustable valve for closure restraint for automobile door or panel has valve body controlling flow opening displaced by directing pressure medium onto pressure surface of valve body provided by membrane

摘要

The adjustable valve has a valve body (17) which covers a flow opening and which is moved against the force of a return spring (21) by the pressure of an operating medium, directed onto a membrane (23) acting as a pressure surface of the valve body, for rotation of the latter, to bring an opening in the valve body into alignment with the flow opening. The membrane (23) is contained within a flow channel (25) of the valve body (17) and cooperates with the resetting spring (21) so that it is tipped by the action of the operating medium to release a spring path for the resetting spring.
