    摘要: A shaft sealing assembly is located in a suction chamber of a swash plate type compressor to seal the space between a drive shaft and a housing. A first end portion of the drive shaft is supported by a first radial bearing. A second end portion of the drive shaft is supported by a second radial bearing. The suction chamber is closer to the first end portion of the drive shaft than the first radial bearing is. An axial passage is formed in the drive shaft to connect the suction chamber to the crank chamber. An inlet of the axial passage is closer to the second end portion than the second radial bearing is. An outlet of the axial passage is closer to the second end portion than the first radial bearing is.

    摘要: The compressor has a cooling structure to effectively cool a shaft seal device interposed between a housing of the compressor and a rotary shaft. The front housing has a through-hole through which the rotary shaft extends, and the shaft seal device is arranged in the through-hole. A passage (suction passage portion) is connected to the thorough-hole. An inlet from a portion of the passage to the through-hole is arranged right above the rotary shaft, and an outlet from the through-hole to a portion of the passage is arranged right below the rotary shaft. The passage is connected to a suction pressure region outside the compressor and to the suction chamber via the through-hole.

    摘要: A piston type variable displacement fluid machine includes a drive shaft and a cylinder bore. A piston reciprocates along a line of movement in the cylinder bore in accordance with the rotation of the drive shaft. The stroke of the piston is varied between the maximum stroke and the minimum stroke, which is greater than zero. The displacement of the fluid machine is changed in accordance with the stroke of the piston. A ring groove is formed on the outer circumferential surface of the piston. A piston ring is fitted in the ring groove and moves with respect to the piston in the line of movement of the piston. An allowable movement amount of the piston ring with respect to the piston is greater than or equal to the minimum stroke of the piston.

    摘要: A variable displacement compressor in a refrigeration circuit using carbon dioxide refrigerant. The compressor changes the inclination of a swash plate located in a control chamber in accordance with the difference between the pressure in the control chamber and the pressure in a suction chamber thereby varying the compressor displacement. The compressor includes a control valve that adjusts the difference between the pressure in the control chamber and the pressure in the suction pressure. The control valve controls the flow rate of refrigerant supplied from the discharge chamber to the control chamber thereby adjusting the pressure difference. A controller inputs information from the outside of the refrigeration circuit. The outside information includes the outside temperature, the temperature of a passenger compartment and a target compartment temperature set by a temperature adjuster. The controller sets a target value of the pressure of refrigerant discharged from the compressor in accordance with the outside information. The controller then controls the current supplied to the control valve such that the target discharge pressure is rapidly reached. The compressor reduces unnecessary operation thereby reducing the power consumption and the load.

    摘要: The present invention relates to a refrigerating system and a method of operating a refrigerating system. The refrigerating system includes a compressor, a gas cooler used as a heat-dissipation type heat exchanger, an expansion valve used as a throttling means, an evaporator used as a heat-absorption type heat exchanger and an accumulator, which are connected in series with each other to form a closed circuit. The closed circuit is adapted so that the higher pressure of the closed circuit becomes the supercritical pressure of a refrigerant circulating the closed circuit. This has a control characteristic property wherein the lower evaporating pressure increases as the higher pressure increases. The lower evaporating pressure and the higher pressure are detected, respectively, and if the detected value of the lower evaporating pressure is lower than a target value for the lower evaporating pressure determined based on the above control characteristic property in correspondence to the detected value of the higher pressure, the discharge capacity of the compressor is reduced so that the lower evaporating pressure coincides with the target value.

    摘要: The number of seal members relating to a gas flow control valve can be reduced. A displacement control valve 25 is attached to a fixed coupling surface 193 on the outer wall surface of a rear housing 19. A gasket 45 is interposed between end surfaces 362 and 414 of the displacement control valve 25 side and a coupling surface 193. A sealing elastic layer 452 of the gasket 45 is in close contact with the end surfaces 362 and 414, and a sealing elastic layer 453 is in close contact with the coupling surface 193. A pressure supply passage 30 and a gas passage 413 are communicated with each other via a communication port 454 on the gasket 45. A pressure supply passage 31 is communicated with an insertion recess 33 that is communicated with a valve port 431.
