LOW-NOISE ROTARY PUMP

A rotary pump, preferably a vane cell pump or a pendulum slider pump, includes a stator and a rotor which rotates about a rotational axis within the stator. The rotor includes multiple delivery elements which move radially in relation to the rotational axis, and two adjacent delivery elements limit a delivery cell together with the outer surface area of the rotor and the inner surface area of the stator. At least two delivery cells, preferably two adjacent delivery cells, exhibiting a first maximum cell volume form a first delivery cell group and at least two other delivery cells, preferably two other adjacent delivery cells, exhibiting a second maximum cell volume form a second delivery cell group. The first maximum cell volume of the delivery cells of the first delivery cell group is larger than the second maximum cell volume of the delivery cells of the second delivery cell group. 一种旋转泵，优选叶片单元泵或摆动滑块泵，包括定子和转子，所述转子能够在所述定子内绕旋转轴线旋转，其中，所述转子包括多个输送元件，所述多个输送元件能够相对于所述旋转轴线径向移动，并且两个相邻的输送元件与所述转子的外表面区域和所述定子的内表面区域一起限定输送
