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 provide a solenoid control valve of a simple structure at low cost by reducing the number of parts, omitting a screw coupling part, and reducing as many rubber seal parts as possible. SOLUTION: A pilot valve hole, a hole of a bearing 22 to support one end side of a shaft 24 of a solenoid, and a fitting hole 18 with one end of a sleeve 19 fitted therein are formed in a body 1 on the same axis. Since a movable part of the solenoid is correctly aligned when the sleeve 19 is fitted in the fitting hole 18, a pilot valve element 17 is integrated with the shaft 24. Set values of a main valve and the pilot valve are adjusted by the press-in quantity of a press-fitting member 13 and a bearing 23, and a lower space of a piston 10 and an opening end part of the bearing 23 are covered by the press-fitting members 13 and 29. The solenoid is connected to the body 1 by caulking a yoke 27 to omit any screw part, and the rubber seal member is miniaturized. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an expansion valve wherein the cost of an air conditioner for automobile is reduced by providing a flow passage interruption function.
SOLUTION: An expansion valve 6 for a rear side is constructed with a solenoid regulated pressure valve where outlet pressure of a refrigerant supplied to a rear side vaporizer 7 can be controlled to be constant, and the outlet pressure can be set with an external signal determined by refrigerant temperature at an outlet of the rear side vaporizer 7 detected by a thermistor 8. Hereby, the valve can be brought into a fully closed state by setting the outlet pressure lower than the minimum pressure of the refrigerant in a freezing cycle, so that when use is made of a solenoid regulated pressure valve as the expansion valve 6 for the rear side, a solenoid valve for interrupting a flow passage becomes unnecessary to reduce the cost of an air conditioning apparatus for an automobile.

摘要： PROBLEM TO BE SOLVED: To provide a double-direction valve capable of conducting a fluid to flow into double directions and improved in controllability. SOLUTION: The double-direction valve is provided with a valve unit 1 having a tubular valve body 9 and a solenoid 2 for regulating the opening degree of a valve by controlling the axial directional position of the valve body 9, while the valve body 9 is energized from both sides of axial direction of the same through compression coil springs 16, 27. According to this constitution, a valve which will not be affected by the pressure of the fluid which flows through a first port 4 and a second port 5 which are communicated with the valve body 9 is constituted, and the fluid can be conducted to flow into double directions. In the solenoid 2, a shaft 21 is penetrated through a plunger 20 and both ends of the shaft 21 are supported by guides 23, 24 to obtain a structure wherein the plunger 20 will not be slid in the sleeve 25 whereby a sliding resistance upon the movement of the plunger 20 in the axial direction of the same is lightened remarkably, and the controllability of the plunger 20 is improved.

摘要： PROBLEM TO BE SOLVED: To finely regulate a supercooling degree of a high pressure refrigerant to be controlled and maintained constantly when assembled without losing simplicity and compactness of a structure by providing an urging force regulating member for finely regulating an urging force of an urging means, and forming one of a throttle and a valve seat. SOLUTION: A spring receiving member 7 for receiving a fixed end side of a compression coiled spring 7 is engaged at a male threaded part of its outer periphery with a female threaded part 3c formed on an inner periphery of a stepped cylindrical body 2. A refrigerant passing hole is perforated through an axial position of the member 7 to become a throttle hole 8 for adiabatically expanding the passing refrigerant. Thus, a supercooling degree of a high pressure refrigerant controlled and maintained constantly can be arbitrarily finely regulated by rotating the member 7 when assembled and changing an urging force of a compression coiled spring 6. Further, since the hole 8 is formed at the member 7, its structure becomes simple and compact.

摘要： PROBLEM TO BE SOLVED: To provide a constant differential pressure regulating valve which has excellent characteristics in terms of constant differential pressure and controllability. SOLUTION: An attraction load which depends on the location of a plunger 54 is made less variable, by providing a protruding portion 59 on the end face of a core 55 side of a plunger 54 and by reducing the variation of an attractive force in relation to the gap between the plunger 54 and the core 55. On account of this, the variation of the attraction load which changes depending on the position of the plunger is reduced and the performance for the constant differential pressure is improved. In addition, a shaft 56 which holds the plunger 54 and drives a pilot valve body 44 is rotatably supported at two points of a bearing 50 and another bearing provided in a depressed manner, and the plunger 54 is kept not to contact with the inner wall of a sleeve 53. While the plunger 54 drivers the pilot valve body 44 through the shaft 56, the plunger 54 is made contact-free with the sleeve 53 and then the frictional resistance is drastically reduced and the controllability is improved.

摘要： PROBLEM TO BE SOLVED: To prevent a main valve from being freely vibrated in the lateral direction and from becoming a noise source by inclining the main valve with the energizing force of an exciting means when the main valve is opened, thereby regulating the vibration of the main valve. SOLUTION: A drive rod 19 is pinched between a piston-shaped pressure receiving member 20 and a main valve 16, and the drive rod 19 is arranged at an eccentric position to the main valve 16. When the pressure in a downstream passage 12b is lowered, the piston-shaped pressure receiving member 20 moves the main valve 16 in the opening (separating from a valve seat 15) direction. When the main valve 16 is separated from the valve seat 15 by the drive rod 19 due to this action, the main valve 16 is inclined by the exciting force of a compression coil spring 17 because the drive rod 19 is arranged at the eccentric position to the main valve 16 and compression coil spring 17. The conical face of the main valve 16 is pressed to part of the ridge line section of the valve seat 15, and the vibration of the main valve 16 is regulated.

摘要： PROBLEM TO BE SOLVED: To obtain a supercooling degree control type expansion valve for use in refrigeration cycle in which generation of noise is prevented by urging a valve disc for opening/closing a refrigerant channel in a direction inclining against the axial direction through an urging means thereby suppressing the vibration of the valve disc due to refrigerant flow. SOLUTION: A supercooling degree control type expansion valve 10 placed in a pipe line for passing high pressure refrigerant is closed when a valve disc 14 is pushed against a valve seat 13 formed in a tubular case 12. The valve disc 14 comprises three guide legs 14c, and three supporting leg pieces 14d extending along the inner circumferential surface of a downstream side channel 16b and the valve disc 14 is positioned oppositely to the valve seat 13 while being urged by a compression coil spring 18 from the downstream side. The compression coil spring 18 has no end turn at either end and the valve disc 14 is prevented from being vibrated due to refrigerant flow by urging the valve disc with spring force in the direction inclining against the axial direction thereby pushing the valve disc 14 against the inner circumferential surface of a refrigerant channel 16.
