Abstract

PURPOSE:To enable to change the set pressure of an outlet passage at will by a method wherein the opening area of a working gas passage which leads the gas pressure to a main diaphragm chamber. CONSTITUTION:A switching valve 15 opens a small valve seat 13 and in turn closes a by pass valve 14. Because working gas is led through a passage 17 to the main diaphragm chamber 8, the pressure within the main diaphragm chamber 8 ascends with working gas and exceeds the pressure within the outlet passage 3, resulting for a main diaphragm 9 in generating the force intending to open a main valve 4 against a spring 7. When the force generated at the main diaphragm 9 exceeds the force of the spring 7, the main valve 4 starts to open, allowing to fuel gas to start to flow through a port 5 to the outlet passage 3. Simultaneously the pressure within the outlet passage 3 starts to ascend and feeds-back through a passage 26 to a feedback diaphragm 19.
