摘要： A high pressure fuel pump includes a pump head from which extends a turret, a bore extends along a main axis from a pumping chamber through the turret to an open end. A piston is arranged in the bore and protrudes out of the turret, an outer extremity being provided with a cam follower. A spring is arranged around the piston and slipped over the turret, the spring is compressed between the cam follower and the main part of the pump head. A cup shaped sleeve is arranged around the turret and defines a volume between the turret and the peripheral wall which fills with fuel that has leaked between the piston and the blind bore from the pumping chamber. A bottom face of the sleeve is provided with a hole through which the piston extends. An opening in the peripheral wall allows fuel to exit the volume.

摘要： The present disclosure relates to a pump (100, 200) for supplying high-pressure fuel to a common rail fuel injection system. The pump (100, 200) comprises an elongated aperture (109, 209) forming a pumping chamber (111, 211) and a pressurisation chamber (119, 219); a pumping element (113, 213) configured to reciprocate within the elongated aperture (109, 209) to pump fuel from the pumping chamber (111, 211); and pressurisation means for pressurising fuel in the pressurisation chamber (119, 219). The pressurisation chamber (119, 219) extends at least partially around the circumference of the pumping element (113, 213) to reduce leakage from the pumping chamber (111, 211).

摘要： According to an aspect of the present invention there is provided a pump for supplying high- pressure fuel to a common rail fuel injection system. The pump has a head housing and a pumping chamber is defined within the head housing. A bore for receiving a pumping element is arranged for reciprocal movement within the bore. The pump comprises means for compensating for dilation of the pumping element and/or the bore under operational loads.

摘要： A return spring for a diesel fuel pump pumping mechanism, the spring having a variable external diameter, and having a greater diameter at an end abutting an inlet valve body, than at an opposite end abutting a seat proximate a roller/shoe guide, the spring is formed entirely of a frustoconical section or sections, or with an additional cylindrical section or sections; the spring exhibits decreased resonance during pumping, and has an increased free length, leading to a reduction in stresses in the spring.
摘要翻译：一个复位弹簧用于柴油燃料泵泵送机构，具有可变外径，并在其端部具有更大的直径抵接的入口阀本体，比在相对端抵接的座邻近的辊/滑座引导弹簧，该弹簧完全由一个或多个截头圆锥形部分或另外的圆柱形部分形成; 弹簧在泵送过程中表现出减小的共振，并且具有增加的自由长度，导致弹簧中的应力减小。
