摘要： A plunger stopper is installed to a cylinder hole forming portion of a cylinder forming member. The plunger stopper cooperates with a step portion of a plunger to limit movement of the plunger in a state where a slide surface of the plunger contacts an inner peripheral wall surface of the cylinder hole.

摘要： A plunger stopper is installed to a cylinder hole forming portion of a cylinder forming member. The plunger stopper cooperates with a step portion of a plunger to limit movement of the plunger in a state where a slide surface of the plunger contacts an inner peripheral wall surface of the cylinder hole.

摘要： A cylinder is configured into a bottomed tubular form and includes an inner peripheral wall, an inner bottom wall, an outer peripheral wall and an intake hole and a discharge hole. The inner peripheral wall slidably guides the plunger. The intake hole and the discharge hole communicate between the inner peripheral wall and the outer peripheral wall. A pump housing includes a cylinder receiving hole that includes an inner peripheral wall, into which the cylinder is inserted. A pressurizing chamber is formed by the inner peripheral wall and the inner bottom wall of the cylinder and a distal end outer wall of the plunger.

摘要： A piston can reciprocate in a piston guide cylinder in an axial direction and has a cavity on a piezo driver side thereof. If the piezo driver is energized, a tip of a projecting section of a pushing member pushes a bottom wall of the piston defining the cavity. If fuel pressure of a pressure control chamber increases via a pressurization chamber and a communication passage due to pressurization by the piston, a needle moves in a valve-opening direction against a first compression coil spring. Since the piston has the cavity, a movable mass of the piston is reduced while securing axial length of a sliding section. Thus, fuel leak from the sliding section between the piston and the piston guide cylinder can be suppressed, and an inertial resistance caused in the piston can be reduced.
