ABSTRACT:
A swash plate type compressor includes a front head portion having a suction chamber and a discharge chamber sectioned by a partition wall formed on an inner surface of the front head portion, and having at least one upper discharge guide groove and at least one lower discharge guide groove formed in an upper portion and a lower portion of the discharge chamber, respectively, a rear head portion having a suction chamber and a discharge chamber sectioned by a partition wall formed on an inner surface of the rear head portion, and having at least one upper discharge guide groove and at least one lower discharge guide groove formed in an upper portion and a lower portion of the discharge chamber, respectively, to correspond to the upper and lower discharge guide groove of the front head portion, a cylinder installed between the front and rear head portions or inside the front and rear head portions and having a plurality of bores installed such that pistons are capable of sliding therein, at least one upper discharge passageway and at least one lower discharge passageway for connecting the upper and lower discharge guide grooves of the front and rear head portions, respectively, a drive shaft installed to penetrate the cylinder and rotated by a driving source, and a swash plate installed at the driving shaft to be inclined and having the pistons installed at an end portion of the swash plate. Thus, in the swash plate type compressor, the compressed refrigerant can be quickly discharged with less resistance so that, when the liquid refrigerant is sucked, compression noise can be reduced.
