TEMPERATURE-COMPENSATED PRESSURE REGULATOR

摘要

A pressure regulator or pressure element with a valve, whose valve closing body 10 separates an admission pressure chamber 2 from a back pressure chamber 3, has a diaphragm 12 that is under spring pressure in the opening direction of the valve closing body 10. The diaphragm 12 separates the back pressure chamber from a reference pressure chamber 4 which is filled with a gas that is under such pressure that its ability to expand compensates the temperature dependence of the compressive force of the spring in order to compensate the pressing force of the compression spring 13, which changes with changing temperature.
