摘要： The invention relates to a proportional valve that can be electromagnetically actuated for controlling the delivery rate of a high-pressure fuel pump, comprising an electromagnet (1) for acting on an armature (2) that can be moved in a reciprocating manner, wherein the armature (2) is coupled to an axially movable valve piston (4) by means of a tappet (3) such that the stroke of the armature (2) causes an axial movement of the valve piston (4) against the spring force of a spring (5). According to the invention, the axially movable valve piston (4) is accommodated in a flanged bush (6), by means of which the proportional valve can be connected to a housing part (7) of the high-pressure fuel pump. The invention further relates to a high-pressure fuel pump having such a proportional valve for controlling the delivery rate.

摘要： Provided is a high-pressure fuel supply pump that maintains oil-tight performance even when the fuel pressure is high, and includes a small and lightweight discharge valve structure. The structure prevents the reduction in oil-tight performance caused by the deformation of the seat part due to the high back pressure that the discharge valve receives. The structure also makes the provision of a flow path compatible with the size reduction and weight reduction of the discharge valve.
The valve body of the discharge valve includes a guide part and a curved contact surface. Thus, the seat part is formed with Hertzian contact and this formation exerts high oil-tightness even when a high back pressure is applied to the valve body. The guide part is provided to the valve body. This provision determines the position of the curved contact surface. This determination reduces the size and weight of the valve body.
摘要翻译：提供一种高压燃料供给泵，即使在燃料压力高的情况下也能够保持油密性能，并且具有小而轻的排出阀结构。该结构防止由于排出阀接收到的高背压导致的座部件的变形而导致的油密性能的降低。该结构还使得提供与排放阀的尺寸减小和重量减轻相一致的流动路径。排出阀的阀体包括引导部和弯曲接触面。因此，座部形成有赫兹接触，即使向阀体施加高的背压，该形成也具有高的油密性。引导部件设置在阀体上。该规定确定弯曲接触表面的位置。这种确定减小了阀体的尺寸和重量。
