ABSTRACT:
A single-headed piston type swash-plate compressor has a cylinder block having cylinder bores in which a plurality of pistons are slidably received. A first housing is attached to a first end of the block to form a crank chamber therebetween, and a second housing is attached to a second end thereof to form an annular suction chamber and a central discharge chamber therebetween. The chambers are partitioned by an annular wall portion projected from an inner wall of the second housing such that the suction chamber surrounds the discharge chamber. A drive shaft rotatably is extended through the crank chamber, and a conversion mechanism is provided on the shaft for converting a rotating movement of the shaft into a reciprocating movement of each piston in the corresponding bore such that a suction stroke and a discharge stroke are alternately executed therein. During the suction stroke, a fluid is introduced from the suction chamber into the bore, and during the compression stroke, the introduced fluid is compressed and discharged from the bore into the discharge chamber. The cylinder block has a portion extended radially and outwardly from a side thereof, and the portion has a damping chamber formed therein. The discharge chamber has an elongated portion extended radially and outwardly therefrom, the elongated portion being in communication with the damping chamber through a small passage formed in the extended portion of the block.
