GAS PRESSURE REGULATOR Russian patent published in 2000 - IPC

FIELD: engine manufacture, specifically, devices regulating pressure of fuel gas in gas internal combustion engines. SUBSTANCE: special structural implementation of pressure regulator ensures that under all operational conditions except those corresponding to complete opening of throttle valve of engine passage of gas through power regulating conduit is shut. While engine runs under conditions of low load gas is supplied to it through no-load system alone. When engine runs at full-power design of pressure regulator provides for increase of total supply of gas by low-pressure regulator thanks to additional supply of gas through conduit of power regulation which leads to enrichment of combustible mixture ensuring winning of maximum power from engine. EFFECT: increased accuracy and stability in regulation of gas flow under all conditions in the course of long time and provision of optimum supply of gas under various operating conditions of supercharged engine. 1 dwg
