And, described rotating vane is made up of blade axis hole, blade, seal groove and diaphragm seal, multiple rotating vanes are installed in rotating vane groove, and with in rotating vane groove, multiple rotating vanes being installed, with being connected by blade triangle chock between adjacent two rotating vanes in rotating vane groove, rotating vane and housing joint are shaped with multiple seal grooves, and seal groove is connected with diaphragm seal by stage clip, and diaphragm seal forms and seals moving cooperation with housing inner chamber, described blade bottom is provided with blade axis hole.

And, described rotor end-face periphery is coaxially shaped with annular seal groove, in this annular seal groove, be embedded with multiple seal rings, between adjacent two rotating vanes, multiple seal rings are installed, and adjacent two seal rings adopt concavo-convex embedding structure to connect, wherein a side sealing ring is shaped with projection, and opposite side seal ring is shaped with blind slot, and sealing stage clip is installed in blind slot.

And described rotor end-face is uniform is shaped with multiple Cooling Holes.

And described track end face is shaped with oil leab.

Advantage of the present utility model and economic effect are:

1, the utility model has overcome the technical barrier of conventional rotors motor diaphragm seal quick abrasion, poor sealing, by rotating vane axle is supported in the track on end cap, rotor is slided along track, has avoided the inordinate wear of diaphragm seal; Meanwhile, by the seal ring of setting-in in annular seal groove, improved the sealing in engine cavity; The utlity model has that volume is little, good airproof performance, high, the cheap feature of compression ratio, there is good practicability.

2, the utility model is by the blade triangle chock being slidably installed between adjacent two diaphragm seals in same rotating vane groove, in the time that rotor banding motive sealing sheet rotates, triangle chock can be adjusted diaphragm seal height in time, diaphragm seal and housing inner chamber and both sides end cap is formed and seal moving cooperation.

3, the annular seal groove that the utility model is coaxially shaped with by rotor end-face periphery matches with seal ring, can effectively improve the sealing between rotor and both sides end cap.
