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.
