IMPROVED DEVICE FOR DELIVERING FUEL FROM FUEL TANK INTO INTERNAL COMBUSTION ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: invention relates to fuel injection devices. Proposed device for delivering fuel from tank into internal combustion engine contains low-pressure pump. High-pressure pump, in its turn, contains body forming inner chamber and at least one piston set into operation by control element placed in said inner chamber. Two-position valve is located in joint between low-pressure pump and high-pressure pump. Two-position valve contains element set into action from low- pressure pump to open intake channel in joint and to deliver additional fuel into inner chamber. Low-pressure pump is set into operation mechanically by means of special device connected to engine shaft. Size of element is chosen so as to provide setting into action even at low speed of engine shaft when starting said engine. EFFECT: simplified design, improved reliability and response. 12 cl, 1 dwg
