摘要： A scroll compressor has a suction chamber, a stationary scroll and a movable scroll. The stationary scroll has a circumferential wall and a stationary volute portion. The movable scroll has a movable base plate and a movable volute portion. A circumferential surface of the movable base plate and an inner surface of the circumferential wall form a sealing portion at sections located close to each other with a narrow clearance. The sealing portion moves along the inner surface of the circumferential wall as the movable scroll orbits. Lubricating oil in a bottom portion of a suction chamber is supplied to a compression chamber defined by the volute portions from the suction chamber. This effectively utilizes lubricating oil retained in the bottom portion of the suction chamber

摘要： A controller controls a displacement of a compressor which is installed in a refrigerant circuit of an air-conditioning system. The controller has a pressure difference detector (40, 54). An air conditioning switch (81) turns the air conditioning system on. A temperature detector (85) detects the temperature in a compartment. A control valve (CV) controls the displacement of the compressor such that the pressure difference detected by the pressure difference detector (40, 54) approaches a target value. A computer (70) determines the target value. The computer (70) changes the target value, depending on the detected temperature. The computer (70) limits the target value to a target value limit. After a predetermined time expires from when the air conditioning switch (81) is turned on, the computer (70) changes the limit. This permits the displacement of the compressor to be promptly and reliably changed.

摘要： A control valve is used for a cooling apparatus having a compressor including a displacement variation mechanism and an external refrigerant circuit (30) connected to the compressor to form a cooling circuit. The discharge displacement of the compressor is regulated by controlling a control pressure, which acts on the displacement control mechanism. The control valve has a housing and an internal passage. The internal passage includes a valve chamber defined in the housing. A valve body is located in the valve chamber and controls the opening degree of the internal passage. A first pressure sensing structure senses the differential pressure between two pressure monitoring points (P1,P2) in the cooling circuit, that is, a primary pressure (22), and transmits a force corresponding to the primary pressure to the valve body. A second pressure sensing structure senses a secondary pressure, which is different from the primary pressure, and applies the secondary pressure to the valve body (43). The valve body (43) is positioned in the valve chamber (46) by a combination of forces corresponding to the primary pressure (PdH-PdL) and the secondary pressure (PdL-Pc), and the opening degree of the internal passage is controlled accordingly.

摘要： A variable displacement compressor includes a rotor (17), which is fixed to a drive shaft (16), and a pivotal swash plate (18), which is supported on the drive shaft (16) and slides in an axial direction along the drive shaft (16). A hinge mechanism (20) is located between the rotor (17) and the swash plate (18). The hinge mechanism (20) rotates the swash plate (18) integrally with the rotor (17) and guides the pivoting and the sliding motion of the swash plate (18). The hinge mechanism (20) includes a swing arm (43), which extends from the swash plate (18). The swash plate (18) is made of aluminum or aluminum alloy material. The swing arm (43) is separate from the swash plate (18) and is made of iron-based metal material. Therefore, while the swash plate (18) is light, the hinge mechanism (20) is strong.

摘要： A displacement control mechanism used for compressor is installed in a refrigerant circuit. The compressor has a bleed passage (27) and a supply passage (28). The displacement control mechanism includes a first control valve (CV1) and a second control valve (CV2). The first control valve (CV1) includes a first valve body (41) and a pressure sensitive member (54). The first valve body (41) adjusts the opening size of the supply passage (28). The pressure sensitive member (54) moves in accordance with a pressure in the refrigerant circuit. A pressure detection region (K) is located downstream of the first valve body (41). The second control valve (CV2) includes a second valve body (82). The second valve body (82) adjusts the opening size of the bleed passage (27). The second valve body (82) moves in accordance with the pressure of the pressure detection region (K). When the pressure of the pressure detection region (K) increases, the second control valve (CV2) decreases the opening size of the bleed passage (27). This permits to start with rapid cooling performance.

摘要： A vehicle air conditioning apparatus includes a refrigerant circuit (30). The air conditioning apparatus is driven by an engine (101). The air conditioning apparatus includes a variable displacement compressor (104). An external information detector (65, 66, 67, 68, 69) detects external information used for the air conditioning. An E/G-ECU (63) controls the output of the power source. An A/C-ECU (61) is connected to the E/G-ECU (63) via a communication line (64). The A/C-ECU (61) computes a target value of the displacement of the compressor based on the external information. The A/C-ECU (61) sends the computed target value to the E/G-ECU (63). The E/G-ECU (63) controls the displacement of the compressor based on the computed target value. This is capable of rapidly changing the discharge displacement in accordance with the driving condition of the engine (101).

摘要： Scroll compressors (100, 110) may include a movable scroll (20) that is disposed opposite to a fixed scroll (2). At least one compression chamber (32) is defined between the fixed scroll and the movable scroll. A motor (49) drives the movable scroll, so that the movable scroll revolves (orbits) relative to the fixed scroll. The movable scroll includes a front portion (20b) that slidably contacts the fixed scroll. The front portion receives the pressure of the pressurized refrigerant that is disposed within the compression chamber. The movable scroll also includes a rear portion (20a) that slidably contacts a portion (4a) of a compressor housing. The motor is disposed within a motor chamber (45) defined within the compressor housing. A first conduct route (94) communicates discharged refrigerant from a discharge-side region (85) to the motor chamber. A second conduct route (97, CL) communicates refrigerant from the motor chamber to a suction-side region (98), thereby adjusting the pressure within the motor chamber, so that the opposing pressing forces applied against both sides to the movable scroll can be appropriately adjusted in order to improve compressor efficiency.

摘要： A control apparatus that promptly increases the displacement of a compressor after the compressor is started while liquefied refrigerant is lingering in an external circuit (30). The control apparatus includes a restricting passage (82). The restricting passage (82) is located in a first pressure introduction passage (37), through which the pressure (PdH) of the first pressure monitoring point (P1) flows to the control valve (CV). The restricting passage (82) decreases the pressure of refrigerant that flows through the passage (37). When the compressor is started while liquefied refrigerant is lingering in the external circuit (30) and the pressure (PdH) of the first pressure monitoring point (P1) is abruptly increased, the restricting passage (82) reduces the increase of the pressure that is detected by the control valve (CV). Therefore, the displacement of the compressor is promptly increased.
