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： 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 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： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend through the flange. A pin is supported in each support hole. The ends of each pin are received in guide holes. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.

摘要： The air conditioning system 100 may include a compressor 101, a heating circuit 152, and a capacity controller 181. The compressor 101 has a suction port 116, a discharge port 120, a driving unit 130 provided within a driving chamber 110, a first passage 201 and a second passage 105. The driving unit 130 may decrease compressor output discharge capacity when the pressure within the driving chamber 110 increases. The first passage 201 may connect the discharge port 120 to the driving chamber 110 and the second passage 105 may connect the driving chamber 110 to the suction port 116. The capacity controller 181 may open the first passage 201 when the refrigerant discharge pressure results predetermined pressure. By opening the first passage 201, the high-pressure refrigerant may be released from the discharge port 120 to the driving chamber 110 through the first passage 201. Thus, the pressure within the driving chamber 110 may increase, the compressor output discharge capacity can be reduced, the abnormally high discharge pressure of the compressor 101 can be alleviated by the reduction in the compressor output discharge capacity.
