摘要： An expansion valve is provided to move refrigerant of high humidity to a lower part of a temperature lowering part through a bypass path, thereby preventing a temperature of the refrigerant from rising excessively and a lubrication oil of a compressor from being temperature-deteriorated. An expansion valve includes a bypass path(3a,3b) formed between a high pressure refrigerant inlet supplied with refrigerant of high pressure or a low pressure refrigerant outlet for transmitting refrigerant of low pressure to an evaporator(4), and a refrigerant path through which refrigerant discharged from the evaporator flows. Through the bypass path, liquid refrigerant of high pressure or gas/liquid mixture refrigerant of low pressure flows to a lower part of a temperature lowering part.

摘要： A control valve for a variable displacement compressor is provided to control the flow rate of discharged refrigerant, and to reduce costs by requiring no check valve to be provided at a refrigerant outlet port of the compressor. A control valve for a variable displacement compressor comprises a first control valve(10A), a second control valve(10B) and a solenoid units(10C). The first control valve controls a flow rate of refrigerant which the first control valve allows to flow from a discharge chamber of the compressor to a refrigerant outlet port of the compressor. The second control valve controls a flow rate of refrigerant which the second control valve allows to flow from the discharge chamber into a crankcase of the compressor based on a differential pressure across the first control valve, to change a displacement of the compressor, to thereby control the flow rate of the refrigerant allowed to flow by the first control valve to be constant. The solenoid section sets the flow rate of refrigerant which the first control valve is to allow to flow.

摘要： An electromagnetic control valve (20) of a fast response compression volume control apparatus for a refrigeration cycle is provided which connects and blocks a crank chamber (12) of the compressor to and from a discharge chamber (4) such that the differential pressure between the crank chamber (12) and a pressure and the suction chamber is maintained at a predetermined value. The differential pressure is changed by changing the electromagnetic force of the electromagnetic control valve such that the discharge volume of the refrigerant is controlled and the compression volume becomes a predetermined one in a prompt action without a time delay when the electromagnetic force is varied.

摘要： The stroke of a valve element 8 of an expansion valve is set such that refrigerant flows at a flow rate 1.0 to 1.4 times the flow rate corresponding to the set tonnage. This means a limit of the valve lift to fully open state during start-up and prevents an unnecessary and excessive refrigerant flow and reduces flow noise of refrigerant during start-up and allows to save driving force for the compressor.

摘要： In the control valve 1 for a variable displacement compressor, a bellows 30 is disposed between a pressure-sensing piston 16 and a core 22 in a pressure-sensing chamber S. A pressing force-transmitting member 90 fixed to a plunger 21 is interposed between the pressure-sensing piston 16 and the bellows 30. A spring 63 which urges the pressing force-transmitting member 90 toward a valve section 10 is disposed between the pressing force-transmitting member 90 and the bellows 30. As a result, even if the bellows 30 contracts due to high suction pressure Ps, the pressing force-transmitting member 90 is held by the spring 63 urged toward the valve section 10 to fully open the valve section 10 via the pressure-sensing piston 16, whereby the minimum operation of the compressor can be maintained.

摘要： A valve element 11 of a proportional valve is integral with a piston 13 having a cross-sectional area equal to that of a valve hole constituting a valve seat 10. A diaphragm 14 having an outer peripheral portion secured to a body 1 contacts a pressure-receiving end face of the piston 13. The diaphragm 14 is mounted in a displaced state such that when the valve element 11 is seated, the pressure receiving area of the diaphragm 14 is at a maximum and equal to that of the valve element 11. A variation of the pressure receiving area of the valve element 11 when the valve element moves away from the valve seat 10 is canceled out a corresponding variation of the pressure receiving area of the diaphragm 14. This prevents the valve to open or close by itself due to a difference between the pressure receiving areas. A sliding portion of the piston 13 is sealed by the diaphragm 14 preventing internal leakage.

摘要： A low cost block-type expansion valve 6 contains a hollow cylindrical strainer 20 in a space provided for introducing high-pressure liquid refrigerant. The strainer 20 surrounds a valve element 17. Refrigerant introduced into a refrigerant pipe-connecting hole 12 has to flow through the strainer 20 to the upstream side of the valve element 17. Since the shape of a valve body 11 does not need to be substantially changed for the provision of the strainer 20, it is possible to provided the expansion valve 6 without an increase of the manufacturing costs.
