Abstract
A compressor according to the present invention has a housing including a first and second cylinder bores. The inner diameter of the first cylinder bore is smaller than that of the second cylinder bore. In suction process, refrigerant gas is directly drawn from an inlet port into a first suction chamber. The refrigerant gas is flowed from the first suction chamber into a first compression chamber. In contrast, refrigerant gas is drawn through the inlet port, a first suction passage, the first suction chamber, a first communication passage, a swash plate chamber and a second communication passage and into a second compression chamber. According to the above-described compressor, wherein the inner diameter of the first cylinder bore is smaller than the second cylinder bore, the difference of the amplitude of the intake pulsation between the first compression chamber and the second compression chamber can be suitably reduced.
