IPC: F02M61/16
Filed: 1983-10-22
Abstract: PURPOSE:To eliminate a cavity generated in high-pressure system upon finishing the injection of fuel and prevent the breakage of the parts of the device by a method wherein an oil path, connecting the oil reservoir of a fuel valve to the oil supplying pipe of a fuel pump, and a non-return valve, opening this oil path when the pressure of the fuel is lower than a predetermined pressure, are provided in the device. CONSTITUTION:An oil supplying chamber 105 and plunger chamber 106 in the fuel pump 1 are filled with the fuel fully and when a plunger 102 is lifted up, an oil supplying port 10 is closed and the compression of the fuel is begun. When the pressure of the plunger chamber 106 is increased and a discharging valve 107 is pushed up, the fuel is sent out into an injection pipe 2. Subsequently, the pressures of the oil path 208 and an oil reservoir 207 in the fuel valve 3 are increased, a needle valve 201 is opened and the fuel is injected out of a nozzle 206. On the other hand, the pressure in the system is reduced to a value lower than an oil supplying pressure due to the effect of the suck- back collar 108 of a delivery valve 107 upon finishing the injection, then, a non return valve 601 is opened and the fuel flows into a high-pressure system through a pipe 606, a non-return valve chamber 607 and the oil path 605 whereby reduction of pressure may be restricted.
