摘要

Improvements in the construction of pressure regulators, maneuvered by membrane with safety valve and unilateral connection of the inlet and outlet pipe, in which the pressure medium, after traversing a hollow valve seat body, through annular ducts are led towards the outlet, and the regulating valve body, as well as the safety valve body, are disposed axially one after the other, characterized by that to the valve stem supporting the regulating valve plate a second valve rod, independently of and guided with it, which supports the safety valve plate, is coordinated and the second valve rod independently of the regulating rod is triggered and actuated by the membrane, half of a spring, which rests on the crankcase of the regulator.
