FIELD: automatic pressure control devices.
SUBSTANCE: invention is aimed at stabilizing the gas outlet pressure during surge flow of high pressure gas. It is achieved by limiting the compression of the bellows, since the bellows plug, which is centred and guided by the cylindrical surface of the body, is additionally pressed against a spacer mounted on the plug outside the bellows by an unregulated power spring, and a friction damper is installed on the spacer, compressing the pusher, and there are stroke limiters bellows, interacting with supports made on the plug when the bellows is compressed.
EFFECT: stabilizing the gas outlet pressure during surge flow of high pressure gas.
