摘要： A device for locking a cam shaft of a fuel injection pump for an internal combustion engine including a coupling block connected to a projecting portion of the cam shaft rotatably supported by a pump body. The cam shaft locking device includes a locking pin threadably engaged in a threaded opening formed in one of a fixed member on the pump body and the coupling block, and a locking plate formed with an opening for fitting the locking pin therein secured to the other of the fixed member and the coupling block, whereby the cam shaft can be locked in an optimum rotational position.

摘要： An electromagnetic selector valve for changing the fuel paths between the fuel tank, fuel supply pump and fuel injection pump of an engine is energized by an energization control unit including a monostable multivibrator only for a predetermined time interval just after the engine key switch has been turned off. An on-off valve disposed in the pipe line between the fuel tank and the electromagnetic selector valve or the pipe line between the electromagnetic selector valve and the fuel injection pump, is opened during the time the engine is operating. When necessary, the on-off valve is continuously opened by another energization control unit including a monostable multivibrator for a predetermined time interval just after the engine key switch has been turned off.

摘要： A stopping device for an engine supplied with fuel by a fuel injection pump including a change-over valve, and an actuator for actuating the change-over valve in response to an engine shutdown operation. The change-over valve is movable between a first position to which it moves at engine startup to connect a fuel tank with an inlet of a fuel supply pump driven by the engine and connect an outlet of the fuel supply pump with an inlet of the fuel injection pump, and a second position to which it moves in response to an engine shutdown operation to connect the inlet of the fuel injection pump with the inlet of the fuel supply pump and connect the outlet of the fuel supply pump with the fuel tank. The actuator includes a solenoid and a key switch operative to energize the solenoid to move the change-over valve to the first position in response to an engine startup operation, hold the change-over valve in the first position during engine operation, and de-energize the solenoid to move the change-over valve to the second position in response to an engine shutdown operation.

摘要： A fluid pressure chamber is formed in a fuel injection valve, in which a piston connected to a nozzle needle is reciprocally disposed. The pressure chamber is supplied with fluid under pressure from a fluid pump through a check valve. The pressure chamber is also connected with an orifice. When a fuel is distributed from a fuel injection pump under pressure and supplied to the injection valve, the nozzle needle is lifted by the distributed fuel under pressure. When the nozzle needle is lifted, the fluid in the pressure chamber is compressed for causing a fluid pressure applied to the piston in a valve closing direction, whereby the starting of the fuel injection becomes gentle, decreasing combustion noises.
摘要翻译：在燃料喷射阀中形成流体压力室，其中连接到喷嘴针的活塞相互配置。压力室在流体泵通过止回阀的压力下被供给流体。压力室也与孔连接。当燃料从燃料喷射泵在压力下分配并供给到喷射阀时，喷嘴针在压力下由分配的燃料提升。当喷嘴针被提起时，压力室中的流体被压缩，以使得在关闭方向上施加到活塞的流体压力，由此燃料喷射的启动变得平缓，燃烧噪声降低。
