摘要： A plunger type high-pressure fuel pump includes a plunger reciprocated in a cylinder. A fluid pressurizing chamber of the pump has a chamber with a capacity that changes with reciprocation of the plunger. An electromagnetic valve is provided between the pressurizing chamber and a fluid suction passage; as well as a discharge valve. The electromagnetic valve includes a valve member including a suction valve; a solenoid coil adapted to displace the valve member; an anchor made of a magnetic material provided integrally with the valve member; and a core forming a magnetic circuit to attract the anchor by the electromagnetic force and dividing the inside of the electromagnetic valve into a hermetically closed space and an external space communicating with the fluid suction passage. The anchor or the core is provided with a fluid passage through which fluid can flow between the hermetically closed space and the external space formed by the anchor and the core, respectively when the suction valve is in an opened state.

摘要： The objective of the present invention is to dampen operating sounds of an electromagnetic drive mechanism used for a variable displacement to reduce an individual difference depending on apparatus due to the control mechanism in a high-pressure fuel supply pump change over time or installation tolerance.To achieve the above objective, the present invention is configured such that before the electromagnetic drive mechanism supplies a drive force to a plunger which is electromagnetically driven by the electromagnetic drive mechanism, another displacement force situates the plunger in a specific position. When compared to an occasion where the plunger is displaced all strokes by a magnetic biasing force, the above configuration is able to reduce the force of impact on a member (for example, valve body) mounted to the plunger and a restricting member, thereby damping the collision noise. Furthermore, since an extra member, such as a damping member, is not required, individual difference depending on apparatus do not easily occur.

摘要： A high-pressure fuel pump comprises a pressurizing chamber for pressurizing fuel, an outlet valve for discharging the fuel pressurized in the pressurizing chamber to an outlet passage, a relief passage for connecting the outlet passage located downstream of the outlet valve and the pressurizing chamber with each other while bypassing the outlet valve. A relief valve device is provided in the relief passage and adapted to open when an internal pressure of the outlet passage becomes higher than that of the pressurizing chamber, thereby providing communication between the outlet passage and the pressurizing chamber. The relief valve includes a relief spring mechanism for pressing a relief valve to a relief valve seat. At least the relief spring mechanism among members of the relief valve device is provided outside the pressurizing chamber in the pump body.

摘要： To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.
