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： The present invention relates to a multicylinder rotary compressor and a compressing system and a refrigerating unit each provided with the multicylinder rotary compressor. Two-stage (cylinder) rotary compressor provides a motor-operating element and a rotary compressing element in a closed vessel, and the rotary compressing element includes a first rotary compressing element and a second rotary compressing element. This two-stage rotary compressor provides a refrigerant gas switching means comprised of a communicating pipe one end of which is opened in the closed vessel and the other end of which is opened in a back pressure portion for a vane having no spring in the second rotary compressing element, a branch pipe provided in the midway portion of this communicating pipe and a three-way valve attached to a branch point in the branch pipe. Further, a through hole in the second rotary compressing element is closed with a sealing member. During high rotation speed a high pressure refrigerant gas, which flows from the closed vessel to the communicating pipe is supplied to the back pressure portion for the vane so that the second rotary compressing element is made in an operation mode, and during low rotation speed the high pressure refrigerant gas is relieved through the branch pipe so as not to supply the back pressure portion for the vane with the refrigerant gas, whereby the second rotary compressing element is made in a non-operation mode. The present invention forms a compressing system and a refrigerating unit each using the two-stage rotary compressor.

摘要： An object of the present invention is to promote oil separation in a sealed container, thereby decreasing the amount of oil discharged to the outside of a compressor. The compressor comprises discharge hole provided at position facing the end surface of a rotor and through which a compressed refrigerant from first and second rotary compression elements is discharged into the sealed container; and a refrigerant flow path which is extended from a space surrounded with a coil end of a stator projecting from the end surface of the rotor to a rotary compression mechanism side to a space of an air gap between the rotor and the stator, to guide the compressed refrigerant discharged through the discharge hole to an electromotive element opposite to the rotary compression mechanism side. The outlet of this refrigerant flow path opposite to the rotary compression mechanism side faces the inner wall surface of the sealed container, and the volume of a space between the inner wall surface of the sealed container and the electromotive element is 1.5 times or more and 15 times or less that of a space between the rotary compression element and the electromotive element.
