Patent ID: 7000420

Claim:
A compressor, which is configured to suck refrigerant gas from an external refrigerant circuit, compress the sucked refrigerant gas and discharge the compressed refrigerant gas, said compressor comprising: a cylinder having a plurality of bores; a front housing being coupled to a front side of the cylinder and forming a crank chamber; a driving shaft supported to be freely rotatable with respect to the cylinder and the front housing; a slanting plate element mounted on the driving shaft; a single-headed piston connected to said slanting plate element for linearly reciprocable displacement within one of the bores of the cylinder; and a rear housing being coupled to and closing a rear side of the cylinder, wherein the rear housing comprises: a discharge chamber provided at the center of the interior of the rear housing, so that the refrigerant gas discharged from the cylinder through a plurality of discharge holes remains in the discharge chamber before being discharged to the external refrigerant circuit; a suction chamber surrounding the discharge chamber, so that the refrigerant gas sucked from the external refrigerant circuit remains in the suction chamber before being moved to the cylinder; and a pulsation pressure reduction conduit provided at a rear side of the rear housing, said conduit having a single inlet led to the discharge chamber and an outlet led to the external refrigerant circuit, and said conduit extending in a radial direction of the rear housing, wherein the single inlet of the pulsation pressure reduction conduit through which the discharged gas of the discharge chamber passes is positioned at a position at which the pressure pulsations of the discharged gas at the respective discharge holes are substantially equal, said position of said single inlet depending on relative positions of the discharge holes in the discharge chamber, an overall configuration of the discharge chamber, and a volume of space occupied by the pulsation pressure reduction conduit in the discharge chamber.
