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

摘要： A motor-driven compressor performs suction, compression, and discharge of refrigerant. The compressor has four cylinder bores and four pistons. A swash plate is integrally rotated with a drive shaft. A transmission mechanism transmits rotation of the swash plate to the pistons. The ratio of the discharge pressure to the suction pressure when the discharge displacement of the compressor is maximum, that is, the compression ratio, is in a range of 2 to 4.5. The compressor is constructed to permit the size of the motor to be minimized.

摘要： An air conditioning system includes an compressor 110 having a driving chamber 110, a suction port 116 and a discharge port 121, a first passage 107 that connects the discharge port 121 to the driving chamber 110 by opening a capacity control valve 140, a second passage 105 that connects the driving chamber 110 to the suction port 116 and a driving means 130 that can change the output discharge capacity of the compressor by changing the pressure in the driving chamber 110. The refrigerant can be released from the driving chamber 110 to the suction port 116 separately from the second passage 105 if the driving chamber reaches a predetermined high-pressure state. In such an air conditioning system, abnormally high pressure problems are overcome that utilizes a hot gas bypass heater. In particular, heating performance is improved, because high pressure refrigerant is not released from the hot gas bypass heater circuit into the cooling circuit. Further, an excessively high-pressure state in the driving chamber 110 can be prevented.

摘要： A hybrid compressor selectively driven by an engine and an electric motor. The hybrid compressor includes a variable displacement compression mechanism. When the compression mechanism is driven by the motor, the cooling capacity of a refrigeration circuit that includes the hybrid compressor is adjusted by controlling the inclination of the swash plate and the motor speed. In the control procedure, the inclination angle of the swash plate and the motor speed are controlled so that the compression mechanism and the motor are most efficiently operated to achieve the required cooling capacity. Therefore, the hybrid compressor is constantly operated with maximum efficiency.

摘要： An air conditioning system 100 may include a compressor 101 having a driving chamber 111, a heating circuit 310 and a controller 203. This system may release high pressure refrigerant from the compressor discharge port 141 into the compressor driving chamber 111 by opening a capacity control valve 181 when the discharge pressure of the refrigerant discharged from the compressor 101 exceeds a predetermined reference value. By increasing the pressure within the driving chamber 111, the compressor discharge capacity can be reduced. As a result, the discharge pressure of the compressor 101 will be reduced by the reduction in the compressor discharge capacity. Further, the controller 203 may decrease the reference value in accordance with a value related to change in the discharge pressure. As a result, the capacity control valve 181 can be opened at an early stage of the increasing of the discharge pressure if the discharge pressure increases rapidly.

摘要： A solid polymer electrolyte type fuel cell system having a reduced size and weight, which exhibits an improved efficiency. To supply reaction gas to an anode or a cathode, a water lubricated type compressor is employed with the following operational advantages. The face pressure of sliding faces of the water lubricated type compressor, that is the compression ratio and number of revolutions thereof, can be greatly improved, as compared to the conventional oil free type compressor. The compression efficiency is improved by reducing of leakage of reaction gas between the sliding faces. No oil film is formed so as not to deteriorate the battery performance. The size of the water lubricated type compressors can be greatly reduced to about one-third to a half of the conventional oil free type compressor. In addition, the improvement of the compression efficiency and reduction of the friction loss result in a great reduction of driving power. Hence, the fuel cell system with the present arrangement is practical particularly when used as a power supply for driving a vehicle, which is severely required to have a reduced size and weight and to be economical.

摘要： A compressor has a plurality of cylinder bores defined around a rotary shaft in a cylinder block and a plurality of double-headed pistons accommodated in the respective cylinder bores. The pistons compress refrigerant gas in a plurality of front and rear compression chambers defined in the bores in the front and rear of the respective pistons according to the rotation of a cam plate mounted on the rotary shaft. The compressor has bearing that receive thrust loads applied to the rotary shaft during operation of the compressor. The pistons create a net thrust load determined by the difference between the maximum of the sum of loads applied to the front sides of the pistons by the refrigerant gas in the front compression chambers and the maximum of the sum of loads applied to the rear sides of the pistons by the refrigerant gas in the rear compression chambers. The pistons transfer the net thrust load to the rotary shaft in a predetermined direction.

摘要： A wave cam is rotatably and integrally mounted on a drive shaft of a compressor. Pistons are connected to cam surfaces of the wave cam via shoes. The shoes move relatively to the cam surface along a predetermined orbital path. The predetermined orbital path defined on the cam surfaces is ground by bringing a grinding surface of a grinding stone, attached to a rotary shaft, into contact with the cam surfaces. During grinding, the grinding surface is perpendicular in respect with the cam surface. The axis of the grinding stone coincides with the axis of the rotary shaft.

摘要： A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.
