摘要： PROBLEM TO BE SOLVED: To realize a low cost by simplifying a displacement control valve in a swash plate type variable displacement compressor in the form of varying a delivery displacement by varying a pressure in a swash plate chamber. SOLUTION: In the swash plate type variable displacement compressor, a part of fluid pressurized in a delivery chamber 28 is fed to the swash plate chamber 23 to impart a back pressure to a piston 7 and the back pressure is varied using the displacement control valve 29. A closing valve such as a two-way solenoid valve is merely used as the displacement control valve 29. If this closing valve is duty-controlled, a displacement of the compressor can be continuously varied. This compressor is used as a coolant compressor for a vehicle air conditioner and if it is constituted such that a displacement of the compressor is varied at least corresponding to an operation state of a vehicle or an engine by detecting torque of the compressor and interlocking a control device or the compressor with a control device for the vehicle or the engine, drivability of the vehicle air conditioner and a fuel consumption rate of the engine can be enhanced.

摘要： PROBLEM TO BE SOLVED: To change a theoretical delivery capacity in good responsiveness, in a variable displacement compressor. SOLUTION: A rocking member 110 is supported rockingly in a condition regulating (impeding) rotation around a center line Lo by a hook (oldham) type universal joint-shaped rocking support member 114, and a control pressure Pc is applied to act in a back surface side (control pressure chamber 102a) of a restriction member 116 constituting the support member 114, to variably control a tilt angle θ of the rocking member 110. In this way, in addition to unnecessariness for considering an amount of blow-by gas, by controlling the control pressure chamber 102a of small volume, the tilt angle θ is made to the controllable, then a theoretical delivery capacity can be changed in good resposiveness.

摘要： PROBLEM TO BE SOLVED: To provide a compressor which presents a high reliability (durability) even when it is operated at a high delivery pressure. SOLUTION: A shaft 1 and an oscillating member 10 are in a non-contact state by holding the oscillating member 10 by a piston 6 and a swash plate 4. Additionally, the oscillating member 10 is pressed directly by a wave coil spring 20 which is constituted by winding a linear corrugated material in a coil shape. It is thus possible to prevent generation of sliding resistance between the shaft 1 and the oscillating member 10. Furthermore, it is possible to prevent buckling phenomenon of the spring by using the wave coil spring 20.

摘要： PROBLEM TO BE SOLVED: To reduce a power loss of a compressor and attain its clutchlessness, by using a valve mechanism closing a suction passage of the compressor when an air conditioner is off, cutting off refrigerant gas, and placing the inside of the compressor substantially in a vacuum condition, so as to solve a compression loss. SOLUTION: When a control valve 17 comes to be placed in an off-condition from opening at off-time of an air conditioner, the second control pressure passages 16a, 16b are interrupted, so as to prevent refrigerant gas of a control pressure chamber 10 from flowing, on the other hand a delivery pressure acts in the control pressure chamber 10 through the first control pressure passage 13, so as to move a spool 11 in an opening/closing valve 5, and a suction passage 7 is interrupted. Here, a compressor 1 is driven to rotate, so as to generate a substantial vacuum condition in the compressor 1, the compressor 1 without a power loss by compression work is obtained, and clutchlessness is attained.

摘要： PROBLEM TO BE SOLVED: To prevent drop of expansion efficiency at a time of expansion operation when an oil separator is mounted on a compression and expansion machine. SOLUTION: The compression and expansion machine 10 blows out compressed refrigerant to a separation chamber 14 from a high presser chamber 111 with a restrictor 113 in operation of a compressor mode, and centrifugally separate oil 100 mixed in refrigerant by swirl flow around a pipe 116 and stores the same in an oil reservoir chamber 117. An oil return valve 200 is provided between a bottom part of the oil reservoir chamber and a return flow passage 300. The oil return valve has a structure to be opened by difference of viscosity of oil and refrigerant. Oil is returned to a low pressure side and is circulated in the compression and expansion machine when oil exists in the oil reservoir chamber in a compression mode and in early part of start of expansion mode. The oil return valve is closed to prevent bypass of high pressure refrigerant at a time of power recovery and energy recovery efficiency is increased when oil does not exist in expansion mode.
