Document Type and Number:
Japanese Patent JP4273599
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the sliding speed of a control member controlling an inflow timing. SOLUTION: A refrigerant compression mechanism part 20 and a refrigerant expansion mechanism part 30 are connected to a drive shaft 60. The expansion mechanism part 30 is connected to a refrigerating circuit 4R using carbon dioxide as a refrigerant. The expansion mechanism part 30 is stored rotatably in a cylinder 31 and connected to the drive shaft 60, and a rotor 33 dividing a refrigerant expansion chamber 32 is provided in the cylinder 31. The expansion mechanism part 30 comprises a revolving member 80 rotated in synchronous with the rotation of the rotor 33, merely revolving about the cylinder 31, and opening and closing a refrigerant suction port 71 according to the rotation of the rotor 33. The revolving member 80 is installed opposedly to a closing member 70 of the cylinder 31, and forms therein an opening 81 communicating with a suction port 71 of the closing member 70 at a specified timing corresponding to the rotation of the rotor 33.
