摘要： A variable displacement type gear pump has gear chambers, one of which is a specific gear chamber. A suction passage (35,36,37) is formed in the housing so as to communicate with suction-side spaces (31,33). An outlet passage (41) communicates with discharge-side spaces (32,34). A return passage (50) returns the fluid discharged to the discharge-side space of the specific gear chamber to the suction passage. The return passage communicates with the suction passage at a confluence portion located upstream side of the suction-side space. An opening and closing valve (51) opens the return passage in a small displacement operational state. A check valve (45) is located between the discharge-side space of the specific gear chamber and the outlet passage for preventing the fluid discharged from the gear chamber other than the specific gear chamber from flowing into the discharge-side space of the specific gear chamber in the small displacement operational state.

摘要： A control valve used for a variable displacement type compressor. The compressor has a crank chamber (5), a discharge pressure zone, and a supply passage (28). The supply passage (28) connects the crank chamber (5) to the discharge pressure zone. The control valve is located in the supply passage (28). The control valve has a valve body (41). The valve body (41) adjusts the size of the opening of the supply passage (28) in accordance with the discharge pressure. The valve body (41) is exposed to the pressure of the supply passage (28). The valve body (41) moves in accordance with the discharge pressure such that the displacement is varied to counter changes of the discharge pressure. The direction in which the valve body (41) moves in response to an increase of the discharge is the same as the direction in which the valve body (41) moves when the pressure of the supply passage (28) increases.

摘要： A scroll type compressor has a housing, a fixed metal scroll member and a movable metal scroll member. The fixed and the movable scroll members each have a base plate and scroll wall extending therefrom. The fixed scroll member is fixed to the housing. The movable scroll member engages the fixed scroll member to trace an orbital motion when driven by a crank mechanism. The scroll members define compression chambers. Resin tip seals are respectively provided on distal ends of the scroll walls and slidably engage the metallic surfaces of the facing base plates. The tip seals seal the compression chambers. A resin coating layer is formed on a region of at least one of the end surfaces of the base plates that is not contacted by a tip seal.

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： 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 through-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： An air conditioning system 100 may include a compressor 101 having a driving chamber110, a cooling circuit 151, a heating circuit 152 and a controller 189. This system may release high pressure refrigerant from the compressor discharge port 120 into the compressor driving chamber 110 by means of the controller 189. The controller 189 may include a selector 181, a first refrigerant releasing means 183 and a second refrigerant releasing means 185. The selector 181 connects the discharge port 120 and the driving chamber 110 by both the first and second refrigerant releasing means 183, 185 when discharge pressure of the refrigerant has reached a predetermined high-pressure state during operation of the heating circuit 152. When the discharge pressure of the refrigerant results an abnormal high pressure state during the operation of the heating circuit 152, the high pressure refrigerant is released from the discharge port 120 into the driving chamber 110 not only by a single refrigerant releasing means 185 but by double refrigerant releasing means 183, 185. Therefore, the high pressure refrigerant can be swiftly released into the driving chamber 110 to increase the pressure in the driving chamber 110 and the necessary time for reducing the compressor discharge pressure can be minimized. Thus, the abnormal high discharge pressure can be quickly alleviated.
