摘要： A compressor including a compressing mechanism accommodated in a housing (11, 12). The mechanism draws refrigerant from an intake chamber (131) into a compression chamber (112) and discharges the refrigerant from the compression chamber (112) to the discharge chamber (132). A seal device (26, 27) prevents leakage of refrigerant from the internal space to the atmosphere between the drive shaft (14) and the housing (11, 12). An isolation chamber (123), which is separately formed in the housing (11, 12), accommodates the seal device. A pressure reducing passage (28) reduces the pressure of the isolation chamber (123) to reduce the pressure difference applied to the seal device.

摘要： The refrigerating system includes a compressor (1), a gas cooler (2) used as a heat-dissipation type heat exchanger, an expansion valve (3) used as a throttling means, an evaporator (4) used as a heat-absorption type heat exchanger and an accumulator (5), 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 (1) is reduced so that the lower evaporating pressure coincides with the target value.

摘要： The electrically driven swash plate compressor consists of an electric motor (21) in the motor chamber (15) and a swash plate (22) with the stationary cylinder block (13) in the crank chamber (16). The swash plate is rotated by the drive shaft (17), whereby the pistons (26,27) are reciprocated in the cylinder block (13). The refrigerant is drawn from the intake port (31A) to the suction chamber (31) and flows into the compression chamber (13E) through port (35A) undergoing compression by the movement of piston (26). The refrigerant is then discharged into the intermediate pressure chamber (32) through port (35B) and then partly discharged into the discharge chamber (33) and partly bypassed into the crank chamber (16) through the communication passage (38). From there the refrigerant is circulated into the motor chamber (16) for cooling of the electric motor (21). Additionally, the cooling effect prevents a deterioration of the state of the lubricating oil in the bearings (18B,23), the pistons (26,27) and their shoes (28,29).

摘要： An air-conditioning system capable of always effectively performing the heating function by selectively using one of a cooling circuit and a heating circuit sharing a variable displacement type compressor is disclosed. An electromagnetic capacity control valve (43) controls the discharge capacity of a variable displacement type compressor (25) in response to the differential pressure between the discharge pressure Pd of a discharge chamber (132) and the suction pressure Ps of a suction chamber (131). The energization and deenergization of the capacity control valve (43) is controlled by a control unit (59). When a cooling command switch (63) is turned on, the control unit (59) deenergizes a switching valve (29) thereby to control the cooling operation while at the same time controlling the discharge capacity by the capacity control valve (43). When a heating command switch (64) is turned on, on the other hand, the control unit (59) energizes the switching valve (29) thereby to control the heating operation while at the same time controlling the discharge capacity by the capacity control valve (43).

摘要： A compressor includes a piston (26) reciprocating in a cylinder bore (25). The piston (26) draws refrigerant into and discharges refrigerant from a compression chamber (36) , which is formed between the piston (26) and a valve plate (14). The valve plate (14) has a discharge port (32) connecting the compression chamber (36) to the discharge chamber (17). A guide passage (41) facilitates the flow of the refrigerant from the compression chamber (36) to the discharge port (32). The guide passage (41) is defined in the compression chamber (36) when the piston (26) is located at the top dead center position. This decreases pressure losses that would otherwise occur when the piston (26) is near the top dead center position.

摘要： -An air conditioning system 100 may include a compressor 101 having a driving chamber 110, a cooling circuit 151, a heating circuit 152 and capacity controllers 301, 401. The compressor 101 may have a suction port 115, a discharge port 120, a driving unit 130 provided within the driving chamber 110. The driving unit 130 decreases compressor output discharge capacity when pressure within the driving chamber 110 increases. The first capacity controller 301 and the second capacity controller 401 are provided in parallel. Each capacity controller may communicate the discharge port 120 with the driving chamber 110 respectively. This system may release high-pressure refrigerant from the discharge port 120 into the driving chamber 110 when compressor suction pressure results predetermined low-pressure state during operation of the cooling circuit. As the result, the heat exchanger in the cooling circuit 151 is prevented from being frosted. Further, the system may release high pressure refrigerant from the discharge port 120 into the driving chamber 110 when compressor discharge pressure results predetermined high-pressure state during operation of the heating circuit. As the result, the heating circuit 152 is prevented from being damaged by an abnormally high discharge pressure.
