Abstract
The present invention relates to a compressor for sucking, compressing and discharging a refrigerant gas from the external refrigerant circuit. The compressor includes: a suction muffler chamber having a suction port formed on the outer circumference of a cylinder block, which has a plurality of bores arranged in a line, and an oil storing part for storing oil, the suction port being communicated with the external refrigerant circuit; and a rear housing connected to the cylinder block to close the rear end of the cylinder block and having a suction chamber and a discharge chamber therein, the rear housing having a suction chamber communicating passage for communicating the suction chamber with the suction muffler chamber at the upstream part of the suction chamber. The compressor can effectively reduce a pressure pulsation of the suction gas and a noise due to the pressure pulsation without causing an increase of the overall length and the entire volume of the compressor, improve lubrication at the time of an initial start, and increase suction and compression efficiencies.
