Claims

[Scope of utility model registration request]

The rotational and reciprocating motion of the plunger causes the fuel to be sequentially pumped to each cylinder of the engine, and a control sleeve is inserted over the plunger and the injection amount is adjusted by opening and closing the overflow passage of the plunger. A start lever and a tension lever that support the control sleeve are supported by a housing with a common shaft, and only the start lever can be tilted in the direction of increasing the injection amount independently of the tension lever. In the distribution type fuel injection pump for an internal combustion engine, a hydraulic actuation device is connected between the start lever and a lever for tilting the start lever in a direction to increase the injection amount, and the hydraulic actuation device is interlocked and connected to an acceleration lever. a first rod connected to the lever and a second rod connected to a piston fitted in a housing, a spring interposed between the piston and the first rod; A distribution type fuel injection pump for an internal combustion engine, characterized in that the discharge fuel pressure of the feed pump is applied to a high pressure chamber defined by the piston.
