ABSTRACT:
A load-regulating device for scroll type compressors comprising a compressor housing, a bracket body, a partition block, a gliding block, a pair of scrolls and a plurality of air chambers, wherein the gliding block being coupled with the pair of scrolls for defining a plurality of air chambers on the scrolls, the pressure variation in the air chambers is then utilized for causing the motion of the gliding block, enabling the compressor to cause the gliding block by means of the pressure variation to motion upwardly as the compressor is actuated, and preventing the fluid in the high-pressure chamber from leaking towards the low-pressure chamber, thus allowing the compressors to quickly build up the pressure; the gliding block is caused by the pressure variation to motion downwardly at times when the compression ratio is excessively high, so as to relieve part of the load, thus improving the performance and reliability of the compressors.
