泵、尤其是燃料高压泵
摘要：
本发明涉及一种泵，其具有至少一个泵部件（18），该泵部件具有一个在壳体部分（24）的缸孔（22）中导行的泵活塞（20），该泵活塞通过一个驱动轴（14）被间接地驱动作往复运动。所述泵活塞（20）通过一个支撑件（42）及一个能转动地支承在所述支撑件（42）中的滚子（46）支撑在所述驱动轴（14）上，其中，所述支撑件（42）至少间接地在所述泵活塞（20）的往复运动的方向上被导向。所述支撑件（42）及泵活塞（20）被一个弹簧（50）向着所述驱动轴（14）加载，其中，所述弹簧（50）在其向着所述驱动轴（14）的端部上绕其纵轴线（21）不能转动地与所述支撑件（42）连接及在其背着所述驱动轴（14）的端部上绕其纵轴线（21）不能转动地与所述壳体部分（24）连接。所述泵活塞（20）与所述支撑件（42）固定地连接，所述支撑件（42）仅通过所述泵活塞（20）在所述泵活塞（20）的往复运动的方向上被导向。
摘要（英）：

The pump has at least one pump element (18), having a pump piston (20) which is guided in a cylinder bore (22) of a housing part (24) and is driven indirectly by a drive shaft (14) in a reciprocating movement. The pump piston (20) is supported on the drive shaft (14) via a supporting element (42) and a roller (46) which is mounted rotatably in the supporting element (42), wherein the supporting element (42) is guided at least indirectly in the direction of the reciprocating movement of the pump piston (20). The supporting element (42) and the pump piston (20) are loaded towards the drive shaft (14) by a spring (50), wherein, at its end which faces the drive shaft (14), the spring (50) is connected to the supporting element (42) such that it cannot be rotated about its longitudinal axis (21) and, at its end which faces away from the drive shaft (14), is connected to a housing part (24) such that it cannot be rotated about its longitudinal axis (21). The pump piston (20) is connected fixedly to the supporting element (42), and the supporting element (42) is guided only via the pump piston (20) in the direction of the reciprocating movement of the pump piston (20).
