射ポンプ。 A fuel injection pump that includes a plunger fitted in a barrel and a pressurizing chamber formed between the barrel and the plunger, and sucks, pumps, and distributes fuel by rotating and reciprocating the plunger. and a dotted body in which a cylinder portion and a spring chamber communicating with the pressurizing chamber are formed;
A piston that is fitted into the cylinder and has one end extended to the spring chamber, a stopper that is slidably provided on the extension of the piston, a spring receiver that is fixed to the extension of the piston, and a spring that is screwed into the cylinder. a first spring that is inserted between the adjusted adjusting screw and biases the piston toward the pressurizing chamber; and a first spring that is substantially orthogonal to the piston axis and comes into contact with the end surface of the stopper to set the position of the stopper. A second spring is inserted between the piston and the stopper to press the stopper against the eccentric pin, and the eccentric pin is rotated according to the engine operating condition to control the amount of piston movement. A fuel injection pump characterized in that it is equipped with a step motor.
