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.

摘要： An improved arrangement for mounting an injection barrel in the mounting bore of a fuel injection pump housing and maintaining the integrity of a fluid seal therebetween. A pumping chamber is defined in each injection barrel. Each injection barrel includes a pair of axially spaced annular seats in the external periphery thereof, preferably beyond the axially opposite ends of the pumping chamber. A respective annular seal is seated in each of the respective seats, and when uncompressed, projects radially beyond the barrel periphery. Each mounting bore includes a pair of chamfered surfaces formed at axially spaced locations, each chamfered surface having a respective diameter sufficiently small for compressively engaging a respective seal when the barrel is mounted. The included angle of each of the chamfered surfaces is relatively small to allow axial adjustment of the mounted position of the injection barrel. The diameter of the mounting bore between the surface of the pump housing and the axially innermost chamfered surface of the pair is always greater than the uncompressed diameter of the axially innermost seal to prevent shaving.
摘要翻译：一种用于将注射筒安装在燃料喷射泵壳体的安装孔中并且保持其间的流体密封的完整性的改进的布置。在每个注射筒中限定了一个泵送室。每个注射筒在其外周中包括一对轴向隔开的环形座，优选地超过泵送室的轴向相对端。相应的环形密封件安置在每个相应的座中，并且当未压缩时，径向突出超过筒周边。每个安装孔包括形成在轴向间隔开的位置处的一对倒角表面，每个倒角表面具有足够小的相应直径，用于当安装筒时压缩地接合相应的密封件。每个倒角表面的夹角相对较小，以允许轴向调节注射筒的安装位置。泵壳表面和轴对内侧倒角表面之间的安装孔的直径总是大于轴向最内密封件的未压缩直径，以防止刮伤。

摘要： A pump assembly includes a pump housing provided with a bore within which a pumping plunger is reciprocal along a plunger axis; a pump chamber defined at one end of the bore within which fuel is pressurised to a relatively high level; and an inlet valve housed within the pump housing and in communication with the pump chamber to control the flow of fuel into the pump chamber. A clamp member applies a clamping load to the pump housing, which has at least a component that is aligned with the plunger axis, through a surface of the pump housing located approximately axially above the bore. The clamp member may be secured to the pump housing by a securing member, which may be positioned radially outwards from the bore and extend through or below a plane through the pump chamber and perpendicular to the plunger axis through the pump chamber.

摘要： A high pressure piston fuel pump having a discharge check valve between the pumping chamber and a pressurized fuel reservoir and a pressure relief valve between the fuel reservoir and a passageway in the housing, wherein the discharge check valve and the pressure relief valve are contained within a single fitting assembly affixed at the pump housing. A first end flow passage is in fluid communication with the pumping chamber and provides an inlet to the discharge check valve and an outlet from the pressure relief valve. A second end flow passage is in fluid communication with the fuel reservoir and provides an outlet for the discharge check valve and an inlet for the pressure relief valve. Advantages include the ability to pre-test the outlet check and pressure relief prior to assembly into the pump housing, and improved flexibility of the outlet fitting location.
