    • Pump (1), suitable for use as a vacuum pump or compressor, has at least one pump piston (2, 3) moving on a circular path, and a pump housing (18), wherein the pump piston (2, 3) is optionally coupled in a rigid manner to one or more further pump pistons (2, 3), moving in an oscillating manner about an axis of rotation (5) on a path of movement correspondingly having two reversal positions. A medium, optionally compressed or pressurized, is discharged via an outlet valve (8). In the course of movement from one reversal position into the other reversal position, an inlet valve (9) being opened; after which, in the course of a pressure buildup, the medium is discharged on a pressure side of the pump piston (2, 3) and taken in on a suction side of the pump piston (2, 3).
    • 适用于真空泵或压缩机的泵(1)具有至少一个在圆形路径上移动的泵活塞(2,3)和泵壳体(18),其中泵活塞(2,3)是 可选地以刚性方式联接到一个或多个另外的泵活塞(2,3),以相对于具有两个反转位置的运动路径上的旋转轴线(5)的振荡方式移动。 任选压缩或加压的介质通过出口阀(8)排出。 在从一个反转位置移动到另一个反转位置的过程中,打开入口阀(9); 之后,在压力累积过程中,介质在泵活塞(2,3)的压力侧排出并被吸入泵活塞(2,3)的吸入侧。
