On the other hand, the sliding vane rotary compressor operates smoothly because the rotor is no longer arranged eccentrically with respect to the cylinder.

Preferably, the opening degree of the first air outlet is smaller than that of the first air inlet; the opening degree of the second air outlet is smaller than that of the second air inlet.

In order to eliminate the friction energy loss generated between the end surface of the sliding vane and the inner wall of the cylinder, preferably, a sliding vane rail is fixedly installed in the cylinder, and the sliding vane rail has the same shape as the cylinder but has a smaller size than the cylinder, so that the distance between the sliding vane rail and the inner wall of the cylinder is equal at all positions; one end of the sliding sheet component is connected with the sliding sheet track in a sliding mode, and the other end of the sliding sheet component is abutted to the inner wall of the air cylinder.

Preferably, the slide assembly comprises a slide, two sleeves and two slide shafts; two the sleeve is located the both ends of gleitbretter lower part respectively, two the gleitbretter axle inlays respectively to be adorned two in the sleeve, the epaxial cover of gleitbretter is equipped with ball bearing, and ball bearing inlays to be adorned in the gleitbretter track.

Preferably, the rotor includes a rotation shaft, spokes, and a rotor body connected to the rotation shaft through the spokes.

Owing to adopted above technical scheme, compare with prior art, the utility model discloses not only improved gleitbretter rotary compressor's compression efficiency and displacement, still made gleitbretter rotary compressor smooth operation. On the other hand, still eliminate because of the friction energy loss that produces between gleitbretter terminal surface and the cylinder inner wall through setting up the gleitbretter track, further improved compression efficiency.
