摘要： PROBLEM TO BE SOLVED: To provide a differential pressure valve with a damper device not affected by the fluctuation of the pressure of a secondary side fluid.
SOLUTION: In an expansion device 1 functioning as a differential pressure valve, a damper device isolated from a space formed immediately after the contraction and the expansion is installed on the side of the refrigerant outlet 13. The damper device has first and second damper chambers 22, 24 demarcated by a piston 19 in a housing 10. A shaft 17 formed integrally with a valve element 16 is so held by the housing 10 as to be moved forward and backward in the valve opening or valve closing direction, and is brought into contact with the piston 19 biased by a spring 20 in the valve closing direction. Since the piston 19 with a large pressure receiving area is isolated from the space formed immediately after the contraction and expansion, the expansion device 1 is not affected by the fluctuation of the pressure of the secondary side fluid.

摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve with a bidirectional throttle capable of reducing the refrigerant flowing noise.
SOLUTION: A movable iron-core 26 is attracted to a fixed iron-core 12 by energizing an electromagnetic coil 16, whereby a bypass passage composed of a communication hole 25, a circular passage 23, a communication hole 22 can be closed, a dehumidifying throttling device mounted in parallel with the bypass passage is composed of projecting parts 32, 33 mounted at both ends of a channel through which the refrigerant passes, and a sleeve 31 moved left and right while guided by a shaft 30 in accordance with the refrigerant flowing direction. As the throttling passage has the circular shape determined by an inner diameter of the projecting parts 32, 33 and an outer diameter of both ends of the sleeve 31, and the refrigerant wetting area is enlarged and a flow rate is reduced in comparison with a conventional restriction passage of small diameter, the flowing noise can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a differential valve with a simple structure.
SOLUTION: A a piston 8 formed integrally with a main valve element 7 is arranged on the upstream side of a main valve comprising the main valve element 7 and a main valve seat 6 to form a chamber for introducing a refrigerant from an inlet port 2. The piston 8 has an orifice 10 communicating with this back-side chamber and a refrigerant passage 9. The back-side chamber is connected to a chamber on the downstream side of the main valve so as to communicate with an outlet port 5 through a refrigerant passage 15 and a pilot valve comprising a pilot valve seat 16 and a pilot valve element 17, so that the refrigerant from the inlet port is supplied to the pilot valve through the refrigerant passages 9 and 15. Since the piston 8 is integrated to the main valve element 7, a member for transmitting the movement of the piston 8 to the main valve element 7 is dispensed with, and the structure can be simplified.

摘要： PROBLEM TO BE SOLVED: To provide an expansion device with a solenoid valve capable of suppressing self-excited vibration without raising costs.
SOLUTION: An expansion valve is used as a stop valve closed by exciting a double purpose valve element 27 by a spring 32 when a solenoid 13 is not energized, and a first iron core 24 holding the double purpose valve element 27 is attracted to a second iron core 25 fixed to a second shaft 20, and displacement of a power element 12 is transmitted to the double purpose valve element 27 when the solenoid 13 is energized.

In adjustment of a degree of overheating of the expansion valve, a load of the spring 30 is adjusted by a pressed-in amount of an adjustment piece 31 into the sleeve 23, and the adjustment piece 31 is fixed to the sleeve 23 by caulking.

摘要： PROBLEM TO BE SOLVED: To provide an expansion valve for controlling supercooling degree, which enables a reduction of fixing space and fixing processes by incorporating the function of a check valve.
SOLUTION: A valve seat 10 is formed midway between refrigerant paths 4 and 6, and a valve body 12 for full-opening and full-closing operation is arranged so as to face the valve seat 10 from the refrigerant path 4. The valve body 12 is disposed at the side of the refrigerant path 4 and is provided with; a differential pressure valve consisting of a housing 26 having a valve seat 38 and a valve body 22; and a through-hole 18 and a slit 16, which constitute an integration, to serve as a throttling channel. In a cooling operation, the refrigerant that has been introduced to the refrigerant path 4 allows the valve body 12 to seat on the valve seat 10 and close the channel, and thereafter flows to the refrigerant path 6 through the differential pressure valve and the through- hole 18, being throttled and expanded by the slit 16. In a heating operation, the refrigerant that has been introduced to the refrigerant path 6 presses and fully opens the valve body 12 and continues to flow to the refrigerant path 4.

摘要： PROBLEM TO BE SOLVED: To control an expansion device by absolute pressure while operating it with relative differential pressure between the pressure of an entrance and the pressure of an exit.
SOLUTION: A differential pressure control valve is composed of a movable valve seat 17 for introducing a cooling medium from a cooling medium entrance 12 therein, and a valve element energized in a valve-closing direction by a spring 21; a shape memory alloy spring 31 energizes the movable valve seat 17 in the valve-closing direction in response to the temperature on the entrance side; and a shape memory alloy spring 36 energizes it in a valve-opening direction in response to the temperature on the exit side to compensate the temperature of a position in the axial direction. Therefore, the pressure on the entrance side and that on the exit side are set to absolute pressure values corresponding to the respective temperatures. Since the set differential pressure is prevented from being changed by the temperature on the entrance side by negating the effect of the shape memory alloy spring 31 when the temperature on the entrance side is above a predetermined value, the pressure on the entrance side is prevented from exceeding the predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide an expansion device which controls high pressure-side pressure such that the pressure does not exceed a predetermined pressure in terms of absolute pressure, while operating in response to differential pressure between pressure at an inlet thereof and pressure at an outlet thereof.
SOLUTION: This expansion device 3 comprises an orifice 28 for expanding refrigerant, a valve element 25 disposed on a downstream side of a valve hole 24 and urged by a shape-memory alloy spring 26 in a valve-opening direction, a shaft 29 disposed to extend through the valve hole 24 and having one end thereof rigidly fixed to the valve element 25, and a spring 31 provided at the other end of the shaft 29, and receiving load in the valve opening direction by differential pressure between pressure at the inlet and pressure at the outlet. The shape-memory alloy spring 26 senses the temperature of refrigerant on the downstream side to perform temperature-dependent correction of a set value of the differential pressure for opening the valve element 25. Therefore, pressure on an upstream side is controlled as if by absolute pressure. Further, when the pressure on the upstream side exceeds a predetermined pressure, the spring 31 is bent to open the expansion valve in this expansion valve 3, and hence the pressure is prevented from rising above the predetermined pressure.
