A scroll-type compressor includes a hermetic case in which a compression section having a pair of spiral scrolls and a motor section for driving the compression section are arranged. The motor section has a rotating shaft coupled to the compression section. A flow passage is formed in the shaft and communicates at its one end with the compression chamber of the compression section and at its other end with a muffler chamber defined above the motor section. An operating fluid compressed in the compression chamber is guided into the muffler chamber through the flow passage, flows around the motor section, and then is discharged from the case.
