摘要： In a piston with an encompassing seal, which is seated slidably in a cylindrical receiving bore of a structural part such as a housing block and which can be acted upon by pressure on at least one end, the piston is intended to have a shoulder for receiving the seal. This shoulder divides a cylindrical running face of the piston of a segment having a jacket face, and a groove is formed into the jacket face for receiving a ring that secures the seal in the axial direction and also acts as a stripper ring protecting the sealing ring.
摘要翻译：在具有封闭密封件的活塞中，其可滑动地位于诸如壳体块的结构部件的圆柱形容纳孔中，并且可以在至少一个端部上受到压力作用，活塞旨在具有用于接收的肩部封印。该肩部将具有护罩面的部分的活塞的圆柱形行进面分开，并且将槽形成为护套面，用于接收将密封件沿轴向固定的环，并且还用作保护密封环的剥离环。

摘要： A reciprocating piston pump having a housing, pistons disposed opposite one another in the housing, an eccentric between the pistons, annular grooves that fit around the piston necks machined into piston ends oriented toward the eccentric, and a U-shaped hoop spring curved radially outside the eccentric in the circumferential direction thereof. The hoop spring includes forklike hoop spring ends which engage the annular grooves and press the piston ends toward the eccentric. In the circumferential direction of the substantially U-shaped hoop spring, a continuation is formed on the hoop spring and together with a stop disk aligned transversely to the eccentric shaft, forms a device that limits the pivotability of the hoop spring about the piston necks. The reciprocating piston pump is usable for instance in hydraulic motor vehicle brake systems and in other hydraulic equipment.
摘要翻译：一种具有壳体的往复活塞泵，在壳体中彼此相对设置的活塞，活塞之间的偏心件，围绕加工成朝向偏心件的活塞端的活塞颈部周围的环形槽，以及径向向外弯曲的U形环形弹簧在圆周方向偏心。环形弹簧包括叉状环形弹簧端部，其接合环形槽并将活塞端部朝向偏心件压紧。在大致U形的环形弹簧的圆周方向上，在环形弹簧上形成一个延伸部，并与横向于偏心轴的止动盘一起形成限制环形弹簧围绕活塞颈部的可枢转性的装置。往复式活塞泵可用于例如液压机动车辆制动系统和其它液压设备。

摘要： A combination electric motor-pump unit which is installed on a body of a vehicle. The pump unit includes motor fastening screws with which the electric motor is fastened to the pump housing and which connect the pump unit to the vehicle body. This significantly reduces the number of required parts. The pump unit is provided for a brake system of a vehicle.
