| PROBLEM TO BE SOLVED: To provide a two-stage rotary vane motor capable of efficiently converting mechanical energy from a variable current of expanding lower temperature gas even under low rotational speed. SOLUTION: The two-stage rotary vane motor is provided with housing shrouds 5a, 5b including a first and a second fluid chambers 13a, 13b provided with specific inlets respectively receiving pressurized refrigerant and a first and a second rotors 15, 17 rotatably mounted inside the chambers 13a, 13b by a shaft assembly body 34 including an output end. Regarding the operation, fluid is induced into the housing shrouds 5a, 5b through both chamber inlets because fluid drives both rotors when mass flow of the drive fluid is high (350 pounds/h). When the driven mass flow drops to a low level (in other words, 100 pounds/h), expanding refrigerant is induced only by passing through the second chamber 13b of the housing shroud and operates only the second rotor 17.

| PROBLEM TO BE SOLVED: To enable an delivery of a gear pump to be switched arbitrarily by providing a rod member allowed to rotate in one body with the second drive gear shaft out of the first and the second drive gear shafts and to make movement in axial direction, and making both drive gear shafts to be connected to or separated from each other in response to the axial movement of the rod member. SOLUTION: When an electromagnetic solenoid 21 is set in its non-magnetized state, the tip of a rod member 16 is faced to an opening hole 17 and a drive gear 8 is rotated, te torque is transmitted to the rod member 16 via splines 18, 19b so as to rotate a drive gear shaft 9. Then, driven gears 2, 3 meshing with drive gears 6, 7 also make rotation to carry out ejection of fluid and then the total of ejection quantities of the first and the second pump mechanism is considered as the ejection quantity of a gear pump. Meanwhile, when the electromagnetic solenoid 21 is magnetized, the rod member 16 is moved and its tip is shifted from the opening hole 17, the drive gear shaft 9 is not rotated and only the ejection quantity of the first pump mechanism is defined to be the ejection quantity of the gear pump.

Each compression mechanism 3 is made up out of a scroll compression element 4, a frame 6 pivotally mounting a driving shaft 5 and of an electric motor 7. When each electric motor 7 is rotated, the turning movement is performed by each turning scroll 8 toward each stationary scroll 9, gas sucked in from each suction pipe 40 is compressed so as to be discharged out of each discharge port 19, and it cools each electric motor, it is discharged out of a discharge port 44 thereafter. In addition, this compressor can be operated in 3 ways, namely, both of the compression mechanisms 3 and 3 are operated by an inverter, one out of 2 compression mechanisms 3 and 3 is driven by the inverter and the other is operated by the commercial power supply, and both of them are operated by the commercial power supply.

| PURPOSE:To control the compressor so as to be capable of preventing the hunting of control by a method wherein the parallel operation of a plurality of compressors is effected under synchronizing the compressor in a compressor loop, which is expected to be stopped, with a capacity regulating loop. CONSTITUTION:The compressor control loop is split into two loops of the loop of capacity regulators V1, V2 for the compressor No.1, whose operating time is longest among the loops and which is expected to be stopped, and the loop of capacity regulators V1, V2 of the compressors No.2, No.3 excluding the loop of the compressor No.1. In accordance with the variation of a load condition, the loop of the compressor No.1, expected to be stopped, is unloaded preferentially while the loops of the compressors No.2, No.3, which are not expected to be stopped, are controlled so as to be on-loaded on the contrary. Operating sequence is from the capacity regulator V1 of the compressor No.2 to the regulator V2 of the same compressor, subsequently from V1 of No.3 to V2 of the same and unloading is controlled from the regulators V1, V2, which are on-loaded for the longest time, while the on-loading is controlled from the regulators V1, V2, which are unloaded for the longest time, sequentially. | ||||||

A rotary compressor for achieving efficient supply of oil into a gap between a vane and a vane groove. The rotary compressor also has a function of closing an oil supply path communicating with the vane groove when the operation of the vane stops for the sake of a variation in compression capacity. The rotary compressor includes at least one compression chamber, a vane to perform forward and rearward movements in a radial direction of the compression chamber, a vane groove to receive the vane and guide the forward and rearward movements of the vane, and an oil supply path communicating with a rear location of the vane groove. The oil supply path is opened when the vane moves forward to the compression chamber, and is closed by the vane when the vane moves rearward.
