Title: Gas-pressure-reducing valve - has quick-action mechanism increasing pressure loss under excess pressure
Inventor: SCHLADERER MAX
IPC: G05D16/06
Filed: 1990-10-31
Abstract: The gas-pressure-reducing valve has a housing (1) divided by a diaphragm (2) into a first chamber (3) with an outlet pipe (8), and an inlet pipe (5) with valve (6); and a second chamber (4) with air vent (11). A governor spring (9) in the  second chamber thrusts the diaphragm towards the first one in opposition to the pressure inside it. When pressure difference between the chambers is below a threshold value, diaphragm movement causes the valve to shut the inlet pipe off. Quick-action mechanisms in the air vent increase pressure loss when pressure in the second chamber exceeds a second threshold valve. USE/ADVANTAGE - Valve shuts off gas supply on diaphragm fracture.
