    • The invention relates to the piston unit of a rotary pump, comprising a rotor 4 placed on the pump shaft 6, a piston 3 placed in the groove 10 of the rotor 4, an insert block 8 placed in the cutout 11 of the piston 3, and a collar 2 to swivel the piston 3 relative to the rotor 4 in the groove 10 of the rotor 4. In the assembled pump the piston 3 is placed in the groove 10 of the rotor 4 and the insert block 8 is in turn placed in the cutout 11 of the piston 3. Two working chambers A and B with changing volume are formed in the cutout 11 of the piston 3 one on each side of the insert block 8 placed on the pump shaft 6, when in the operating pump by revolving the pump shaft 6, the piston 3 swivels in the groove 10 on the rotor 4 with the help of the collar 2.
    • 本发明涉及旋转泵的活塞单元,其包括设置在泵轴6上的转子4,放置在转子4的槽10中的活塞3,设置在活塞3的切口11中的插入块8, 以及在转子4的凹槽10中使活塞3相对于转子4旋转的套环2.在组装的泵中,活塞3被放置在转子4的槽10中,并且插入块8又被置于 活塞3的切口11.在活塞3的切口11中形成两个具有变化的体积的工作室A和B,一个位于插入块8的两侧,放置在泵轴6上,当在操作泵中旋转 在泵轴6上,借助于套环2,活塞3在转子4上的凹槽10中旋转。
