    摘要： A scroll compressor is disclosed. A plurality of grooves (85) communicating with each other are formed on a sliding surface of a thrust bearing (53) subjected to the axial force received by a movable scroll (32). The areas surrounded by the plurality of the grooves (85) make up a plurality of insular pressure receiving portions (83) independent of each other. The pressure receiving portions (83) represent at least one half of the area of the sliding surface.

    摘要： A scroll compressor (11) comprising a thrust bearing (53) including a first sliding surface (100) and a second sliding surface (101) in opposed relation to the first sliding surface (100) is disclosed. The first sliding surface (100) is formed with a plurality of insular pressure-receiving portions (83) surrounded by grooves (85) and independent of each other. The part of the second sliding surface (101) in opposed relation to the pressure-receiving portions (83) is flat as compared with the first sliding surface (100). The outermost front surface of the second sliding surface (101) is formed with a diamond-like carbon layer (101a).

    摘要： A vapor-compression refrigerant cycle system with a refrigeration cycle and a Rankine cycle includes a compressor, a radiator, a gas-liquid separator, a decompression device and an evaporator. In the vapor-compression refrigerant cycle system, a liquid pump is disposed for supplying the liquid refrigerant in the gas-liquid separator to a heater for heating the refrigerant, a cooling means is provided for cooling the liquid refrigerant to be sucked into the liquid pump, and an energy recovery unit for expanding the refrigerant flowing out of the heater is disposed to recover thermal energy in the refrigerant from the heater. When the Rankine cycle is set so that the energy recovery unit recovers the thermal energy, the cooling means cools the liquid refrigerant to be sucked into the liquid pump. Therefore, pumping efficiency of the liquid pump can be effectively improved.

    摘要： After the tooth portion 102b of the stationary scroll 102 and the tooth portion 103b of the revolving scroll 103 have contacted each other on one contact face 121 in the central portion of the scroll (shown in FIG. 5A), when this contact face 121 is shifted to two sliding contact portions 122, 123, the operating chamber V is formed between the two sliding contact portions 122, 123 (shown in FIG. 5B), and the refrigerant introducing port 105a is open to the region on the contact face 121. Accordingly, the operating chamber can be instantaneously changed over while the sealing property is ensured. Due to the above structure, the sealing property for suppressing leakage from the high pressure side at the time of the expansion mode can be compatible with the smoothing property for smoothing a change-over of the scroll operating chamber successively formed.

    摘要： A fluid machine according to the present invention has an expansion-and-compressor device selectively operating as an expansion device for collecting waste heat from an internal combustion engine and converting the collected heat energy into mechanical rotational force, and as a compressor device for compressing refrigerant for a refrigerating cycle for air conditioner. The fluid machine further comprises an electric rotating device selectively operating as an electric power generator and as an electric motor. A power transmission device is further provided between the expansion-and-compressor device and the electric rotating device for selectively transmitting the rotational force from the expansion-and-compressor device to the electric rotating device and vice versa. The power transmission device is composed of a planetary gear train so that it can change rotational speed to be transmitted to the expansion-and-compressor device or to the electric rotating device. Accordingly, the expansion-and-compressor device as well as the electric rotating device can be operated at their most efficient rotational speed.

    摘要： An object of the invention is to minimize energy loss to be generated at a driving shaft and a shaft seal device, when an electric rotating device is driven by an expansion-and-compressor device. According to a feature of the invention, a first driving shaft is rotationally supported by a housing and transmits a driving force from an engine to a second shaft of the expansion-and-compressor device, wherein a shaft seal device is provided on the first driving shaft for air-tightly sealing the inside of the housing from the outside of the housing. A power transmission control device (electromagnetic clutch or one way clutch) is operatively provided in a path between the first driving shaft and the second shaft, so that power transmission from the second shaft to the first driving shaft is cut off, to suppress any energy loss to be generated between the first driving shaft and the shaft seal device.

    摘要： An outer end of a seal element for a fixed scroll is extended to a position close to an end of an inside spiral wall of the fixed scroll, and an outwardly extended portion is formed at an outer periphery of a disc-shaped base plate of a movable scroll, so that a bottom surface of the movable scroll is always kept in a sliding contact entirely with the seal element during the orbital movement of the movable scroll. A thickness of the outwardly extended portion formed at the outer periphery of the disc-shaped base plate is made smaller than that of the disc-shaped base plate, so that the weight of the fluid machine can be smaller.
