Abstract
The invention provides a scroll compressor which comprises a shell, a cover, a compressing mechanism, a support mechanism and a driving mechanism, wherein the cover is arranged at an opening formed in one end of the shell in a covering mode; the compressing mechanism, the support mechanism and the driving mechanism are arranged in the shell. A moving scroll plate is driven by the driving mechanism to make planar movement in a static scroll plate, and therefore a cross-shaped slip ring is driven to reciprocate on a base. A gas-guide hole is formed in the base along the motion trail of the reciprocating motion. The gas-guide hole is partially or completely exposed to the cross-shaped slip ring within every cycle of the reciprocating motion of the cross-shaped slip ring on the base, so that a medium-pressure backpressure cavity communicates with a low-pressure cavity for discharging gas with overhigh pressure in the medium-pressure backpressure cavity; the stabilization of medium pressure is achieved; balanced pressure is further achieved; large friction force between the moving scroll plate and the base is prevented; and therefore, the use performance and the service life of the scroll compressor are guaranteed.
