Example Embodiment
[0025] The present invention will be further described in detail below in conjunction with the embodiments of the drawings.
[0026] See figure 1 -Figure 9, the rotor of the rolling vane pump includes a rotor body 10, a vane body 20 and a roller 40. The rotor body 10 is sequentially provided with a plurality of sliding grooves 30 along its circumferential direction. There are a plurality of sliding vane bodies 20, each The sliding vane bodies 20 are all radially slidably disposed in the corresponding sliding grooves 30, and there are also multiple rollers 40, corresponding to each sliding vane body 20 respectively. Specifically, each roller 40 is rotatably arranged. Fitted to the top of each sliding piece body 20, wherein the top of the sliding piece body 20 is provided with an arc-shaped roller groove 21 for placing the roller 40 and sealing contact with the outer circle of the roller 40. In this embodiment The size of the arc-shaped roller groove 21 is adapted to the size of th...
