摘要

The gas pressure regulator has a safety release valve with first and second valves (V1,V2) that respond to first and second pressures respectively in a rear pressure chamber (3) being exceeded, whereby the second pressure is higher than the first. The first and second valves are combined to form a unit. The first and second valves are arranged to be mutually coaxial.
