Abstract

PURPOSE:To obtain a large control rate of compression volume, by increasing the volume of a space opened to the cylinder part of a housing chamber so that a rotary compressing mechanism does not carry out compression until it pass through a compression volume control mechanism in the cylinder part. CONSTITUTION:In case that a cooling load is reduced by about one-half thereof, a cylinder part 5 is communicated with a bypass passage 6 through a housing chamber 13, coolant gas in the cylinder part 5 is not compressed substantially during the period from the time when a rolling piston 8 has just passed a suction port 6 to the time when the rolling piston 8 comes to the housing chamber 13, and is discharged to the intake side of the compressor from the bypass passage 16. Therefore, the rolling piston 8 is apart from the housing chamber 13 and therefore, the pressure of coolant gas becomes near its low pressure. Accordingly, the amount of coolant passing through an evaporator 20 is reduced to about one-half thereof, thereby, the cooling capacity of the compressor may be obtained, corresponding to the cooling load.
