ABSTRACT:
In a gas pressure regulator a switch valve is provided in a throttle nozzle between an inlet passage and a pressure sensing chamber containing a diaphragm controlling a lever arrangement. The pressure regulator is capable of both pressure reduction and automatic shut off if there is a leak due to gas line damage or other conditions. Preferably a restoring mechanism is provided to reset the regulator after its automatic shut off.
