摘要： An object is to avoid generation of a collision sound of a second vane of a compression system comprising a multicylinder rotary compressor being configured to be used by switching of a first operation mode in which both rotary compression elements perform a compression work and a the second operation mode in which the only first rotary compression element substantially performs the compression work. When the second operation mode is switched to the first operation mode, discharge-side pressures of both the rotary compression elements are applied as a back pressure of the second vane, and thereafter an intermediate pressure is applied which is between suction-side and discharge-side pressures of both the rotary compression elements. When the first operation mode is switched to the second operation mode, a valve device interrupts flowing of a refrigerant into a second cylinder, and thereafter suction-side pressures of both the rotary compression elements are applied as the back pressure of the second vane.

摘要： Previous compressors have employed compressors to compress and circulate refrigerant through a circuit, and have been unable to combine the differing advantages of rotary compressors, scroll compressors and screw compressors. The present invention combines these advantages, as well as inhibiting refrigerant leakage and improving overall performance, by particularly fixing the position of the compression member of the compression element relative to the driving element. The driving element is stored in a sealed container of the compressor. The compression element includes a cylinder having suction and discharge ports and a compression member which compresses a fluid (refrigerant) sucked from the suction port to discharge the fluid via the discharge port; and a vane partitioning the compression space in the cylinder into a low pressure chamber and a high pressure chamber.

摘要： A compressor includes two rotary compressing elements in a vessel. One of the compressing elements operates while the other element is in a non-operating mode. In the non-operating mode, inflow of refrigerant gas into the cylinder of the rotary compressing element is blocked and a suction side pressure of the rotary compressing element is applied as a back pressure to a vane. A compressing system includes the compressor and a controller and operates in first and second operation modes. In the first operation mode, refrigerant gas flows into a cylinder and an intermediate pressure, a result of flow of the refrigerant gas from between a vane and a guide groove into a back pressure portion, between a suction side pressure and a discharge side pressure, is applied as a back pressure to bias the vane against a roller.
