ABSTRACT:
A swash-plate type rotary compressor includes a plurality of cylinders disposed in circumferentially equi-distantly spaced relation to each other around a drive shaft having mounted thereon a swash plate for rotation therewith. The swash plate is rotated to cause pistons to be slidingly reciprocated in the respective cylinders to draw gas containing lubricant and to compress same. Guide walls are provided on both sides of a swash plate chamber for guiding gas introduced into the swash plate chamber to flow over entire side surfaces of the swash plate from an outer periphery toward a center thereof. A plurality of gas guiding passageways are each located between each pair of adjacent cylinders, for guiding the gas flowing to a central portion of the swash plate into at least one low pressure space.
