摘要： The invention relates to a high-pressure pump, especially for delivering fuel for a common rail fuel injection system. The pump includes at least one cam drive having a feeler element which can be set moving in direction of a stroke axis by a cam geometry introduced into the camshaft, the stroke movement being transmittable to a plunger unit. The plunger unit and the feeler element are impinged upon with a force by a compression spring element in the direction of the cam geometry and the plunger unit has at least one contact surface which adjoins the compression spring element. The at least one contact surface and/or the surface of the compression spring element adjoining the same has a friction-reduced surface coating to bring about a torsion decoupling of the compression spring element.

摘要： The invention provides for operation of camshafts, particularly for an injection pump for diesel. A camshaft rotates around a longitudinal axis of a camshaft. The camshaft has at least one cam being in cooperation with a pressure roller driven in a lifting manner. The pressure roller rotates on the peripheral surface of the cam. The upward stroke of the pressure roller is a working stroke during which the pressure roller moves away from the longitudinal axis of the camshaft. During a return stroke the pressure roller moves toward the longitudinal axis of the camshaft. The peripheral surface of the cam has a return stroke section and a working stroke section. The peripheral surface of the return stoke section has a greater friction value than the working stroke section. Thus an operation of camshafts for an injection pump for diesel is provided, securing a rotation of the pressure roller around the circumference of the cam within the whole speed range of the camshaft.

摘要翻译： 本发明提供了凸轮轴的操作，特别是用于柴油的注射泵。 凸轮轴围绕凸轮轴的纵向轴线旋转。 凸轮轴具有与以提升方式驱动的压力辊协作的至少一个凸轮。 压辊在凸轮的外周表面上旋转。 压力辊的向上行程是工作行程，在该行程中压力辊远离凸轮轴的纵向轴线移动。 在返回行程期间，压力辊朝向凸轮轴的纵向轴线移动。 凸轮的圆周表面具有返回冲程部分和工作冲程部分。 返回行程部分的外周表面具有比工作行程部分更大的摩擦值。 因此，提供了用于柴油机的喷射泵的凸轮轴的操作，在凸轮轴的整个速度范围内确保压力辊在凸轮周围的旋转。

摘要： A high-pressure pump has at least one pump element including a pump piston defining a work chamber and driven at least indirectly by a drive shaft in a reciprocating motion, counter to the force of a restoring spring. The pump piston is braced on the drive shaft at least indirectly via a sleevelike tappet, and the restoring spring engages at least the pump piston. A support element in the tappet braces the pump piston toward the drive shaft and is braced at least indirectly on the drive shaft. The restoring spring, via a spring plate, engages the pump piston and the tappet. The spring plate is elastically deformable in the direction of motion of the pump piston in such a way that as a result of its elastic deformation, deviations in the position of its contact faces on the pump piston and on the tappet are compensated for.

摘要： The invention relates to a high-pressure fuel pump for a fuel injection system of an internal combustion engine, having a pump housing and with at least one pump element of a piston which is driven by a cam which interacts with a roller. The free ends of the roller are bounded by two side run-on surfaces which come into contact with mating surfaces during the operation of the high-pressure fuel pump. In order to provide a high-pressure fuel pump which can be produced cost-effectively and has a long service life, the side run-on surfaces are designed as circular ring disc surfaces and, in a central internal region, are released from contact with the mating surfaces.

摘要： The present invention relates to a high-pressure pump, particularly for delivering fuel for a common rail fuel injection system, having a pump body in which at least one cam drive having a cam shaft is received. The cam shaft is pivotally supported about a cam shaft axis in the pump body and/or in a flange body by at least one bearing arrangement. The bearing arrangement includes a radial bearing bush extending in the direction of the cam shaft axis, and an axial bearing washer, which is integrally formed on the radial bearing bush. The axial bearing washer extends in a radial extension direction of less than 90 degrees relative to the cam shaft axis in the non-installed state. The radial extension direction is directed toward the radial bearing bush and can be brought into an axial bearing plane extending at an angle of 90 degrees to the cam shaft axis in the installed state by elastic deformation of the axial bearing washer.

摘要： The present invention relates to a delivery pump, in particular for delivering diesel fuel into a high-pressure accumulator. The pump has a housing and a drive shaft which is accommodated in the latter and is mounted by at least one sliding bearing arrangement such that it can rotate about a drive shaft axis. The sliding bearing arrangement is formed by a bearing bore and a bearing shaft section which extends through the latter. The sliding bearing arrangement has a bearing play which extends in the radial direction between the bearing shaft section and the bearing bore and has a smaller value in the bearing center than at least one bearing edge. A delivery pump for delivering diesel fuel is therefore provided which has a low-wear sliding bearing arrangement.
