ABSTRACT:
A sliding-vane rotary compressor includes a recess defined in a cylinder and to which a discharge hole is open, a cover secured to the cylinder to close the recess, a discharge valve disposed in a valve receiving chamber defined between the cover and the cylinder, and a discharge connecting hole extending in the cylinder and a side block for connecting the interior space of the recess and a high pressure chamber. The compressor thus constructed is simple in size and light in weight due to non-inclusion of a shell which is required in the conventional compressor. Preferably, a displacement adjustment mechanism is incorporated in the compressor for adjusting the displacement of the latter.
