Abstract: A compressor with rotor unloading is presented. The compressor having a housing for supporting a multi-rotor configuration (e.g., a male rotor and two axially aligned female rotors) and a drive motor. A discharge disk is mounted at the discharge end of the male rotor. The length of the male rotor is slightly longer than the length of the female rotors, thereby providing axial clearance between the female rotors and the discharge disk. Lubrication is leaked (or flashed) through these clearances to upper bearings. The motor is supported in the compressor housing. Evaporated refrigerant from the evaporator is inducted into the compressor. The vapor phase refrigerant is compressed by the compressor. The compressed vapor phase refrigerant is then presented to a condenser, condensing the refrigerant to the liquid phase. Thereafter, liquid phase refrigerant is delivered through an expansion valve to the evaporator. The motor, bearings and the compression process itself are cooled and lubricated by the oil in the vapor refrigerant. The unloading is accomplished by allowing selective axial movement of the female rotors of the compressor to effectively reduce/prevent compression at that rotor. The axial movement is actuated by a stepper motor. The expansion valve is actuated and the female rotors are unloaded (i.e., the stepper motors are driven) in response to microprocessor control. Accordingly, the above describes a complete cycle which can be capacity varied.

Abstract: A variable capacity vapor compression cooling system is presented. In the system of the present invention, air conditioning requirements are entered into a microprocessor which controls the system. Liquid phase refrigerant entering an evaporator is regulated by a microprocessor controlled electronic expansion valve. Evaporated refrigerant is delivered to a pair of compressors from the evaporator. The motors for the compressors are controlled by a controller. Each of the compressors has a feed back loop attached thereto for feeding back some of the inducted vapor phase refrigerant. The amount of vapor fed back in each loop is regulated by a corresponding microprocessor controlled multi-purpose valve. The compressed vapor phase refrigerant is then presented to a condenser which condenses the refrigerant to the liquid phase which is used for cooling, as is well known in the art. Thereafter, liquid phase refrigerant is presented to an economizer where vapor phase refrigerant (i.e., flash gas) is drawn off. The amount of vapor phase refrigerant drawn off is regulated by a microprocessor controlled electronic expansion valve. This vapor phase refrigerant is presented to the multi-purpose valves where it is directed to the respective compressors. The liquid phase refrigerant is delivered to the evaporator with the flow thereof being regulated by a microprocessor controlled electronic expansion valve. Accordingly, the above describes a complete cycle which can be capacity varied without unloading of the compressors, as described more completely below. It is an important feature of the system of the present invention that capacity is varied without unloading the compressors.

Abstract: In a swing type rotary compressor, a roller (2) is fitted on an eccentric portion (31) of a drive shaft (3) and installed within a cylinder chamber (11) so as to be able to orbit. On the roller (2), a blade (21) partitioning the cylinder chamber (11) into a compression chamber (X) and a suction chamber (Y) to which a suction port (13) is opened is integrally protruded. On the cylinder (1), a support body (4) swingably supporting the blade (21) is swingably supported. On an outer circumferential surface of the roller (2), a cutoff portion (22) extending forward in a rotation direction from near a blade protruding position on the roller (2) and shifting a suction shut-off point for suction gas sucked from the suction port (13) toward a side of the compression chamber (X) is formed on a side of the suction chamber (Y) with respect to the blade protruding position. With the configuration, only by forming the cut-off portion with a simple cutting operation applied on an outer circumference of the roller (2), suction resistance in sucking suction gas into the suction chamber (Y) and passage resistance in supplying suction gas from the compression chamber (X) to the suction chamber (Y) via the cut-off portion (22) are reduced and thus, its compression capacity can be exactly adjusted. Furthermore, its manufacturing cost can be reduced by sharing various parts in common.

Abstract: A sliding vane type rotary compressor, of which refrigerating capacity at the high speed operation of the compressor is suppressed by making use of suction loss involved when refrigerant pressure in the vane chamber becomes lower than the pressure of the refrigerant supply source in the suction stroke of the compressor. The compressor has a rotor, vanes slidably carried by the rotor, a cylinder accommodating the rotor and the vane, side plates fixed to both sides of the cylinder for closing both open ends of the vane chambers defined by the rotor, vanes and the cylinder, and suction and discharge ports serving as passages for communicating the vane chambers with the outside of the compressor. A spacer for adjustment of the refrigerating capacity is disposed in the suction port. When the compressor of the invention is used in the refrigeration cycle of an automobile air conditioner, it is possible to obtain a desired refrigerating capacity controlling characteristics of the compressor matching the characteristics of the associated engine and automobile, simply by selecting a suitable spacer and mounting the same in the sucking section of the compressor, without substantially changing other parts of the compressor.
