摘要： A multistage gear pump for pressurizing fluid includes a housing, a drive shaft and a gear assembly. The drive shaft is rotatably supported in the housing. The gear assembly is disposed in the housing. The gear assembly includes at least first and second gear trains. Each train has a pair of drive and driven gears that are engaged with each other. The drive gear is provided on the drive shaft and followed by the driven gear. The first gear train and the second gear train are arranged so that fluid sequentially passes therethrough as the drive shaft rotates. A theoretical discharge capacity of the first gear train is larger than that of the second gear train.

摘要： A control valve (CV) is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve (CV) has a valve housing (45). A valve chamber (46) is defined in the valve housing (45). A valve body (43) is accommodated in the valve chamber (46). A pressure sensing chamber (48) is defined in the valve housing (45). A pressure sensing member (54) separates the pressure sensing chamber (48) into a first pressure chamber (55) and a second pressure chamber (56). The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber (55). The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber (56). The pressure sensing member (54) moves the valve body (43) in accordance with the pressure difference between the first pressure chamber (55) and the second pressure chamber (56) such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber (55) and the second pressure chamber (56) forms a part of the refrigerant circuit.

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.

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.

摘要： In the piston type variable displacement compressor of the present invention, in the crank chamber 5 in which the crank mechanism is arranged, the outlet 28A of the gas supply passage 28, for supplying refrigerant from the discharge chamber 22, is open at an upper position of the crank mechanism in the peripheral wall section of the housing. The control valve 29 is arranged in the middle of the gas supply passage 28, so that a flow rate of the refrigerant supplied into the crank chamber 5 via the gas supply passage 28 can be adjusted. Mist-like lubricant is mixed with the refrigerant. Therefore, even when the flow rate of the refrigerant is low, the crank chamber 5 can be excellently lubricated.

摘要： A shaft sealing assembly (26) is located in a suction chamber (19) of a swash plate type compressor to seal the space between a drive shaft (18) and a housing. A first end portion of the drive shaft (18) is supported by a first radial bearing (24). A second end portion of the drive shaft (18) is supported by a second radial bearing. The suction chamber (19) is closer to the first end portion of the drive shaft (18) than the first radial bearing (24) is. An axial passage (60) is formed in the drive shaft (18) to connect the suction chamber (19) to the crank chamber (17). An inlet (60a) of the axial passage (60) is closer to the second end portion than the second radial bearing is. An outlet (60b) of the axial passage (60) is closer to the second end portion than the first radial bearing (24) is.

摘要： A centrifugal compressor for compressing gas has a casing, a rotary shaft, an impeller, a diffuser, a first scroll, a second scroll, a first passage, a second passage, and a switching member. The rotary shaft is supported by the casing. The impeller is rotatably fixed to the rotary shaft, and sends the gas radially outward to a flow path downstream thereof. The diffuser is formed around the impeller. The first scroll is formed around the diffuser. The second scroll is formed between the diffuser and the impeller. The first passage is formed from the impeller to the first scroll through the diffuser. The second passage is formed from the impeller to the second scroll. The switching member switches the flow path between the first passage and the second passage by opening and closing the diffuser.
