GAS PRESSURE REGULATOR Russian patent published in 1998 - IPC

FIELD: design of gas internal combustion engines for regulation of supply gas pressure. SUBSTANCE: upper and lower pressure chambers are equipped with sensitive members, which are designed as bellows which have rigid bottom. Bellows in upper and lower pressure chambers are mounted so that inner chambers are in addition split into two chambers each of which is designed as closed chambers with alternating volume. Regulating locking members for gas pressure in upper and lower pressure chambers are designed as sleeves with radial holes inside which slide valves are located. Said slide valves are connected through nuts by means of piston rods to inner sides of rigid bottoms of bellows. Radial hole of corresponding sleeve is connected to upper pressure chamber of regulator by means of channel. EFFECT: increased functional capabilities. 1 dwg
