Title: Fuel booster pump for internal combustion engine
Inventor: OKADA YOSHIHIRO
IPC: F02M59/02
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To improve durability of a seal member to seal a plunger and to increase a lubricant pressure at an engine low speed area so as to operate a variable valve gear normally. SOLUTION: A pump part 1A for fuel consists of a plunger 6 reciprocating in a cylinder 3 and feeds high pressure fuel to a fuel injection valve 15. To prevent a leakage of fuel, the plunger 6 is sealed with a seal member 18. By reciprocating a piston part 22 formed integrally with the plunger 6 in a back pressure chamber 23, an auxiliary pump part 1B for lubricant is constituted. Lubricant discharged from an oil pump 29 is further pressurized and fed to a hydraulic actuator 32 for a variable valve gear. Since the back pressure chamber 23 is filled with lubricant having a pressure higher than the atmospheric pressure, a pressure difference exerted on the seal member 18 is reduced and even when the fuel leaks, the feel is prevented from residing in the back pressure chamber 23.
