PURPOSE: The inside diameter and the length of cylinder are increased. The refrigerant is compressed to the high pressure and the refrigerant of the high pressure is obtained continuously from the small power. CONSTITUTION: A capacity type compressor comprises a first cylinder(21), a second cylinder(22), a cover(25,26), an oil cylinder(27), a third piston(29), a first piston(23), a second piston(24), a rod(30), a connecting member(37), a high-pressure valve(40a,41a,42a,43a), a low pressure valve(40b,41b,42b,43b), a gear pump(45), and a solenoid valve(46,47,48,49). The cover closes the opening part of the second cylinder and the first cylinder. In installed in the oil cylinder and the third piston moves with the pressure of an oil(28). The first piston and the second piston compress a refrigerant(39) whenever it from side to side moves. The rod interlinks the third piston and the first piston and the second piston. The connecting member couples the first cylinder and the second cylinder and the cover so that airtight maintain. The high-pressure valve discharges the refrigerant of the high pressure. The low pressure valve inhales the refrigerant of the low pressure to the inside of the first cylinder and the second cylinder. The gear pump consecutively compresses the oil. |
