摘要： PURPOSE:To provide a rolling piston type compressor with small variation in torque, having a simple structure in which a single rolling piston is used. CONSTITUTION:Fluid is sucked into a first working chamber from a suction port 35 of a housing 2, and is compressed at first in the first working chamber 40 by revolution of a rolling piston 42. Thus obtained compressed fluid is then introduced into a second working chamber 42, and is further compressed by revolution of the rolling piston 42 before it is externally discharged.

摘要： PURPOSE:To simplify the constitution of a rotation preventing mechanism for a scroll type compressor and to reduce the size, weight, and cost. CONSTITUTION:A moving scroll 2 has a vortex-form tooth part 14 and is driven by a rotary shaft 1 and is revolved around a fixed scroll 3, having a vortex-form tooth part 17, and effects compression operation of fluid. To prevent rotation of the moving scroll, a plurality of pin members 9 and 10 are formed in a state to be axially protruded from the end plate 12 of the moving scroll 2 and the inner end face, positioned facing the end plate of the moving scroll, of a casing 4, the pin members being brought into contact with each other. In this case, density of arrangement of the pin members which are moved to a position, where the moving scroll is supported thereby, at a period when rotation torque of the moving scroll is increased can be increased. Regarding the diameters of the pin members 9 and 10, 1/2 of a total sum of the diameters is made equal to an eccentric amount of the moving scroll 2 from a rotary axis, i.e., a revolving radius or is reduced to a value very slightly lower than the revolving radius.

摘要： PROBLEM TO BE SOLVED: To prevent drop of expansion efficiency at a time of expansion operation when an oil separator is mounted on a compression and expansion machine. SOLUTION: The compression and expansion machine 10 blows out compressed refrigerant to a separation chamber 14 from a high presser chamber 111 with a restrictor 113 in operation of a compressor mode, and centrifugally separate oil 100 mixed in refrigerant by swirl flow around a pipe 116 and stores the same in an oil reservoir chamber 117. An oil return valve 200 is provided between a bottom part of the oil reservoir chamber and a return flow passage 300. The oil return valve has a structure to be opened by difference of viscosity of oil and refrigerant. Oil is returned to a low pressure side and is circulated in the compression and expansion machine when oil exists in the oil reservoir chamber in a compression mode and in early part of start of expansion mode. The oil return valve is closed to prevent bypass of high pressure refrigerant at a time of power recovery and energy recovery efficiency is increased when oil does not exist in expansion mode.

摘要： PROBLEM TO BE SOLVED: To effectively operate a fluid machine regardless of an operating state.
SOLUTION: The fluid machine incorporates a shift mechanism 400. Thereby, even though a rotation speed in which energy can be effectively recovered at employing a pump motor mechanism 100 as an expansion device is not matched to a rotation speed at which electric power is generated with high power generation efficiency maintained, waste heat can be effectively recovered as electric energy by the shift mechanism 400. Even though the expansion mechanism and compression mechanism allow the shared use by the same mechanism in the case where a volume of an operation chamber offering efficiency as the expansion device does not match a volume of an operation chamber offering efficiency as a compression mechanism, the pump motor mechanism 100 can be effectively operated in either case where the mechanism is employed as the expansion device or as the compression device.
