Abstract
Provided is a piston type compressor which can enhance cooling of internal parts housed in a crank chamber, while effectively reducing an outflow of oil to the outside of a compressor by effectively performing a centrifugal separating operation due to the rotation of a shaft. The compressor includes: a first suction path which directly introduces a working fluid flowed from a suction portinto suction chamberswithout via the crank chamber; and a second suction path which introduces the working fluid flowed from the suction portinto the suction chambersvia the crank chamber, and the second suction path includes: an oil separation passagewhere a working fluid is introduced into the suction chambersfrom the crank chambervia holes formed in the shaft; and a bypass passagewhere the working fluid is introduced into the suction chambersfrom the crank chamberthrough the cylinder blockswithout via the shaft
