摘要： PROBLEM TO BE SOLVED: To provide an expansion device that has a simple structure and can prevent the breakage of a pipe of a high pressure section even if an abnormal increase in pressure occurs.
SOLUTION: The expansion device comprises a differential pressure control valve of which the valve element 7 is lifted as differential pressure between pressure on the upstream side of a refrigerant and pressure on the downstream side, a spring 16 for energizing the valve element 7 in a valve closing direction, and a spring 17 for energizing the valve element 7 in the valve opening direction. The spring 17 is set to have a free length at a lift position of the valve element 7 when the differential pressure is a predetermined value. When the differential pressure is the predetermined value or less, a throttle passage cross-sectional area for the variation of the differential pressure is changed by synthetic loads of the springs 16 and 17, and normal throttle expansion is performed. When the differential pressure expands the predetermined value, the throttle passage cross-sectional area for the variation of the differential pressure is changed significantly by the load of only the spring 16, and more high-pressure refrigerants are relieved from the upstream side to the downstream side.

摘要： PROBLEM TO BE SOLVED: To provide an expansion device capable of preventing breakage of piping of a high pressure part or the like with a simple structure even if an abnormal high pressure is generated. SOLUTION: The flow rate of a refrigerant supplied to an evaporator is controlled by changing an on time of a valve opening control and an off time of a valve closing control with the configuration of a solenoid valve of on/off operation opening/closing a valve hole. Valve closing is performed by an energizing force of a spring 20 so that a valve element integrated with a shaft 21 receives the pressure of the refrigerant introduced from a port 12 in the valve opening direction. When the pressure of the upstream side becomes abnormally high in closing the valve, the abnormal high pressure overcomes the energizing force of the spring 20 to burst open the valve element. Since the pressure of the upstream side is released and reduced at the downstream thereby, the breakage of the piping or the like due to the abnormal high-pressure can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor capable of excellently maintaining a fluid characteristic of a refrigerant flowing out to the crankcase side by passing through a valve hole from the delivery chamber side. SOLUTION: In this control valve 1 for the variable displacement compressor, a conical spring 22 for directly energizing a valve element 17 is arranged in a pressure chamber 52 of suction pressure Ps existing in a position nearer to a shaft 21 than that, not in a pressure chamber 51 of crank pressure Pc communicating on the downstream side with the valve hole 15, and is interposed between the valve element 17 and a body 10. That is, the conical spring 22 is arranged in an area except for a refrigerant passage for directly connecting the valve hole 15 in the body 10 and a crankcase. Thus, since the conical spring 22 does not hinder a flow of the high speed refrigerant flowing in via the valve hole 15 from the delivery chamber side, the fluid characteristic of the refrigerant flowing out to the crankcase side by passing through the valve hole from the delivery chamber side, can be excellently maintained.

摘要： PROBLEM TO BE SOLVED: To provide a control valve for a variable displacement compressor which can maintain the minimum operating condition while keeping a valve portion at a fully-opened state irrespective of the expansion/contraction state of a bellows even in the case of a high suction pressure of the variable displacement compressor. SOLUTION: In the control valve 1 for the variable displacement compressor, the bellows 30 is arranged between a pressure-sensitive piston 16 and a core 22 in a pressure sensitive chamber S. Further, a pressing force transmitting member 90 secured to a plunger 21 is interposed between the pressure-sensitive piston 16 and the bellows 30. A spring 63 for urging the pressing force transmitting member 90 toward the valve portion 10 is located between the pressing force transmitting member 90 and the bellows 30. Accordingly, even if the bellows 30 contracts because the suction pressure Ps is high, since such a state that the pressing force transmitting member 90 is urged to the valve portion 10 by the spring 63 is maintained, a valve element 15 is forced up via the pressure-sensitive piston 16 so that the minimum operating condition can be maintained while keeping the valve portion 10 at the fully-opened state.

摘要： PROBLEM TO BE SOLVED: To provide a capacity control valve of a duty ratio control for a variable displacement compressor, hardly causing resonance phenomenon of a valve element in the vicinity of a valve seat. SOLUTION: The valve element 8 of a valve part 1 controls the opening and closing of a passage between a port 5 for introducing a refrigerant with discharge pressure Pd and a port 6 for leading out a refrigerant with controlled pressure to a crank chamber. A shaft 12 transmits the energizing force of a solenoid 2 to the valve element 8 against the energizing force of a spring 9 energizing the valve element in the valve closing direction. The valve element 8 and the shaft 12 are fitted to each other with a radial very small clearance to move substantially in mutual close adhering state in the axial vibration depending on the frequency of a pulse current. Thus, the axial vibration of the valve element 8 is restrained so that stable operation value is always obtained extending over the whole working region, and resonance phenomenon of the valve element 8 is restrained to improve durability.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling a degree of superheat while accurately calculating it.
SOLUTION: As a expansion device for a refrigerating cycle, a flow control valve is used for controlling fore and aft differential pressure between an inlet and an outlet of an evaporator to be almost constant differential pressure ΔP which depends on a current i to be supplied to a solenoid. At the inlet and the outlet of the evaporator, temperature sensors are provided for measuring their temperatures. A temperature T(Pe) equivalent to evaporation pressure Pe of the evaporator is found from an inlet temperature Tx of the evaporator and the differential pressure ΔP depending on the current i in accordance with the temperature-pressure characteristics of refrigerant. It is subtracted from an outlet temperature Te to calculate the degree of superheat SH. The calculation includes no estimated items, and so the degree of superheat can be accurately calculated for highly accurate control of the refrigerating cycle as well as the inexpensive temperature sensors can be used for detecting elements, resulting in the construction of a low-cost automobile air-conditioning device.

摘要： PROBLEM TO BE SOLVED: To provide an air-conditioner for vehicles capable of saving the power of a compressor without degrading the fuel consumption.
SOLUTION: An air-conditioned state detection means 1 detects the normal air-conditioned state in a cabin, a running state detection means 2 detects an engine-brake state, and when a cold storage mode determination means 3 determines that the cold storage mode is achieved, a refrigerating capacity control means 4 increases the refrigerating capacity, and an air intake ratio control means 5 stores the volume of cold air corresponding to the increased refrigerating capacity in a cold storage material 6. By increasing the refrigerating capacity, the engine load is increased, the engine brake becomes more efficient, and the fuel consumption is not increased in this state by cutting the fuel. The refrigerating capacity required for the regular operation is reduced by using the excessively stored energy in the cold storage material to the cooling of structures to constitute the cabin, and the power can be saved thereby.

摘要： PROBLEM TO BE SOLVED: To prevent oil from staying in an evaporator, to provide an excellent coefficient of performance, and to secure sufficient oil circulation. SOLUTION: An electronic expansion valve 3 is controlled to bring a refrigerant in an outlet of the evaporator 4 into a superheat condition all the time in a usual operation, and is controlled to forcibly have a negative super heat degree periodically by a prescribed period, using a superheat controller 6. A refrigeration cycle is thereby operated under the condition of the excellent result coefficient because the refrigerant sucked into the variable displacement compressor 1 has the super heat degree all the time in the usual operation, and an engine for driving the compressor 1 is allowed to be operated under a fuel consumption saving condition. The lubricating oil staying in the evaporator 4 is able to flow out to a variable displacement compressor 1 side by conducting the control to have the negative superheat degree temporarily, and the compressor 1 is thereby prevented from seizing caused by drying-up of the lubricating oil.
