Detailed Description

For a better understanding of the objects, structure and function of the invention, reference should be made to the drawings, FIGS. 1-4, which are included to illustrate the invention.

Fig. 1 and 2 show a compressor according to the present invention. A roller 2 of the compressor is mounted in a flange 4 of the conventional compressor, and a crankshaft 3 for driving is mounted in the roller 2. The utility model discloses improve on conventional rotary compressor basis, place a gleitbretter 1 in the gleitbretter groove 43 of flange 4, like fig. 4, 1 inside decompression gas supply groove 11 that has the refrigerant that can save of gleitbretter, the refrigerant chooses for use low temperature middling pressure gas, and wherein, decompression gas supply groove 11 is rectangular channel or arc wall. Meanwhile, the flange 4 is provided with the air supplementing channel 41, the axial channel 42 and the radial channel 44, so that the pressure reduction air supplementing groove 11 of the sliding piece 1 introduces low-temperature medium-pressure gas of a system, the pressure difference between two sides of the sliding piece 1 is reduced, the balance of the sliding piece 1 is improved, the reliability of the sliding piece 1 is improved, meanwhile, the air supplementing and enthalpy increasing functions are realized, and the energy efficiency and the reliability of the compressor are improved.

As shown in fig. 3, the air supply channel 41 and the slide groove 43 must be in butt joint, the pressure reduction air supply groove 11 of the slide plate 1 can store refrigerant, the radial channel 44, the axial channel 42, the air supply channel 41 and the slide groove 43 are sequentially and continuously communicated in sequence to realize the admission of make-up air, and the radial channel 44 is connected with an air supply pipe outside the compressor. Furthermore, each air supply channel 41 is simultaneously provided with a plurality of axial channels 42 communicated with the air supply channel; the passage from the radial passage 44 to the axial passage 42 is realized by the cavity between the flange 4 and the baffle 6, or the passage from the radial passage 44 to the axial passage 42, from the axial passage 42 to the air supply passage 41, or both can be arranged on the flange body without passing through the cavity.
