摘要： A high-pressure fuel supply system can reduce collision sounds generated when a plunger collides with a stopper. An electromagnetic valve includes a plunger, a valve seat with which the plunger is moved into and out of contact so that the valve seat is placed into communication with a pressurization chamber when the plunger is moved apart from the valve seat, a stopper for limiting the separation of the plunger from the valve seat, an armature made of a magnetic material and fixedly secured to the plunger, a core arranged in opposition to the armature, a solenoid wound around the core for attracting the armature toward the core through an electromagnetic force when energized, and a spring for urging the plunger toward the valve seat. A groove is formed near opposed surfaces of the armature and core for magnetically saturating a portion of a magnetic circuit generated by energizing the solenoid.

摘要： When a fuel injection valve is mounted on an engine, a distance between a core and an armature during non-energization of a coil can be prevented from becoming narrow. The coil is arranged inside the core, and a body is fixedly secured at its one end to an end of the core. A housing is arranged outside the coil with its one end abutting a cylinder head. A cap is arranged at the other end of the housing, and abuts at its side opposite to the housing with a fastening unit. The armature is arranged for reciprocation inside the body, and is magnetically attracted to the magnetized core. A gap is formed between the housing and the body, with the cap and the core being fixed to each other, and upon mounting the valve on the engine, the housing and the fastening unit abut the cylinder head and the cap, respectively.

摘要： A high-pressure fuel pump of a simple construction is capable of distributing the position of contact between a tappet and a cam so as to improve durability of the tappet without causing seizure of a piston. A cylinder is arranged in a housing, and the piston is received in the cylinder for sliding reciprocation so that fuel is sucked into the cylinder and pressurized by the piston. The tappet is arranged inside one end of the housing for reciprocation, and contacts the cam, which rotates with a camshaft of an engine, so as transmit a driving force of the engine to the piston. A sleeve is arranged between the tappet and the housing, and clearance fitted to an outer peripheral surface of the tappet and an inner peripheral surface of the housing. The tappet is caused to rotate on its own axis by a frictional force generated between the cam and the tappet.

摘要： The object of the present invention is to provide an electromagnetic valve for a variable discharge fuel supply apparatus with improved relief property and high-responsiveness, a small electromagnetic valve, reduced electric current consumption and increased responsiveness, wherein the valve seat has a valve seating surface present in a flat surface facing the direction of movement of the valve at substantially right angle, and the valve is provided with a flow path formed within the valve and a substantially ring-shaped flat landing surface that encircles the flow path within the valve and closes the flow path by coming into contact with the valve seating surface. The electromagnetic valve may be made to cause the outside of the valve to serve as a high pressure side and the flow path within the valve, as a low pressure side, and to cause both the landing surface of the valve and the valve seating surface of the valve seat to be in ring-shaped so that the valve and the valve seat come into contact only through the space between the outer boundary of the landing surface of the valve and the inner boundary of the valve seating surface of the valve seat. Further, the flow path may be formed in a place where it passes the vicinity of said electromagnetic solenoids at the downstream section of the valve. In addition, the flow path within the valve may extend piercing the valve to reach as far as the vicinity of the solenoid coils, and may be connected to the fuel flow path that is formed in the space between the valve outer boundary and the valve holder inner boundary and linked to the low pressure side, and the valve seat having the valve seating surface may be a part formed separately from the valve holder instead of the one united to the valve holder.
