摘要： PROBLEM TO BE SOLVED: To provide a bidirectional constant pressure expansion valve capable of reducing costs in comparison with a conventional one. SOLUTION: According to this bidirectional constant pressure expansion valve 10, a refrigerant pressure at a downstream side can be made constant. As diaphragms 34 are used for bellows 4 used as a pressure sensitive member in a conventional bidirectional constant pressure expansion valve, costs can be reduced. Further as the diaphragms 34 are disposed by every valve port 16A, 16B to change valve openings of each of the valve ports 16A, 16B, characteristics of the valve opening to refrigerant pressure, of the valve port 16B at an indoor heat exchanger 92A side and characteristics of the valve opening to refrigerant pressure, of the valve port 16A at an outdoor heat exchanger 91A side can be respectively properly set.

摘要： PROBLEM TO BE SOLVED: To improve a pressure resistance of an electric flow control valve without increasing the thickness of a lid member of a conventional one.
SOLUTION: In an electric flow control valve, a valve element is rotated by being engaged with a rotor by a drive means such as a stepping motor, and the opening/closing of a valve port communicating with an outlet passage is regulated, so as to control the flow rate. In the electric flow control valve, the cap-like lid member 1 comprises a convex portion 2 or a concave portion 2' and a flange portion 3. A stepped notch 4 which abuts against an upper end of a cylindrical case 6, is provided in an outer peripheral edge portion of a lower surface of the flange portion 2. The cylindrical case 6 and the lid member 1 are secured to each other by plasma welding or the like.

摘要： PROBLEM TO BE SOLVED: To provide a control valve with a more smoothly rotatable valve element in comparison with a current one.
SOLUTION: In this control valve 10, since a part of the valve element 30 facing to a valve seat 12 is formed into a truncated conical shape, a slide-contact area of the valve element 30 with the valve seat 12 can be reduced in comparison with the current control valve, and the valve element 30 can be smoothly rotated. In the valve element 30, since a flat surface 41 of the truncated conical shape thereof surface-abuts on the valve seat 12 of a cylindrical case 11 and slides-contact with the valve seat 12, rotation of the valve element 30 is stabilized. Since an inclined surface 42 of the truncated conical shape is inclined in a range at 1-1.5 degree against the flat surface 41, a clearance between the inclined surface 42 and the valve seat 12 is narrowed to make the air hard to pass through there, and accurate control of a flow is enabled.

摘要： PROBLEM TO BE SOLVED: To provide a control valve of which the number of airtight sealing parts is smaller than a conventional control valve and to provide the control valve capable of converting electric power into rotation of a rotor side field part more efficiently than a conventional control valve. SOLUTION: With the control valve 10, as a large diameter cylinder part 31 and a small diameter cylinder part 32 are integrally molded, the number of the airtight sealing parts can be reduced compared with the conventional control valve in which counterparts of the large diameter cylinder part 31 and the small diameter cylinder part 32 are separately brazed. In the control valve 10, as blazing between parts for supporting a rotor shaft 13 is eliminated and projection welding is conducted to fix them instead, a tool does not become high temperature compared with a case of blazing and a tool 90 which can be strictly aligned can be used. Thus, it is possible to narrow an engagement gap between the large-diameter cylinder part 31 and a rotor side field part 12 and to convert the electric power into rotation of the rotor side field part 12 more efficiently than the conventional control valve.

摘要： PROBLEM TO BE SOLVED: To provide a two-way constant pressure expansion valve which accurately keeps a constant pressure of a refrigerant in comparison with a conventional one.
SOLUTION: As pressure sensitive portions 20A, 20B on one end side and the other end side are fixed to a body 10B in this two-way constant pressure expansion valve 10, the pressure sensitive portions 20A, 20B on one end side and the other end side themselves are not moved according to the flowing direction of the refrigerant. Accordingly, a linear motion supporting mechanism which support bellows to be retractable while controlling buckling of the bellows found in the conventional one, becomes unnecessary. Thus the constant pressure of the refrigerant is accurately kept in comparison with the conventional one without affected by sliding resistance of the linear motion supporting mechanism.

摘要翻译：要解决的问题：提供一种与常规的制冷剂相比准确地保持制冷剂的恒定压力的双向恒压膨胀阀。解决方案：由于一端侧和另一端侧的压敏部20A，20B在该双向恒压膨胀阀10中固定在主体10B上，一端侧的压敏部20A，20B 另一端侧本身不会根据制冷剂的流动方向移动。因此，不需要在常规的波纹管中控制弯曲而支撑波纹管能够缩回的直线运动支撑机构。因此，不受直线运动支撑机构的滑动阻力的影响，制冷剂的恒定压力与常规制冷剂相比是准确地保持的。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a bidirectional constant pressure expansion valve and its manufacturing method capable of reducing costs in comparison with a conventional one. SOLUTION: According to this bidirectional constant pressure expansion valve 10, opposed members 13, 13 are received inside of a copper pipe 12, and bulging lock portions 12T formed by partially bulging the copper pipe 12 inward, are locked with locking grooves 13C formed on outer peripheral faces of the opposed members 13. Thus the pair of opposed members 13 are fixed to the copper pipe 12, the copper pipe 12 bites into angular portions of opening edges of the locking grooves 13C to provide metal seal, and the inside of the copper pipe 12 is partitioned into an one end-side area R1, an intermediate area R3 and the other end-side area R2. As fixing parts of the copper pipe 12 and each of the opposed members 13 are acted as the metal seal, the cost can be reduced in comparison with the conventional one comprising an O-ring 3.

摘要： PROBLEM TO BE SOLVED: To prevent a rotor from being deviated or inclined by the attraction of a fixed coil, and to allow valve elements to be rotated in an oscillating manner and reliably seated on a valve seat surface.
SOLUTION: In an electric flow rate control valve having throttle valve units I and II comprising a valve seat and valve elements on upper and lower parts, deviation or inclination of a rotor 34 when the rotor is attracted by a fixed coil 38 is suppressed by freely fitting the rotor to a shaft so that valve elements 35 and 36 to be engaged with the rotor are reliably seated on the valve seat surface. Independent disk-like projecting parts cut and integrated with the valve seat surface are formed in a three-leaf shape by pressing or the like, and the diameter of a circle to connect centers of the projecting parts is reduced to miniaturize the valve elements. An inclined surface with the angle of 0.05 to 0.10° is formed on sliding surfaces of the valve elements and the valve seat to form a very gentle conical shape. The sliding surface of the valve seat is brought into line-contact with the sliding surface of the valve elements to reduce the sliding resistance between the two.

摘要： PROBLEM TO BE SOLVED: To provide a control valve capable of stably controlling flow rate of fluid regardless of the direction of flow of fluid.
SOLUTION: This control valve 10 changes an area of opening parts of orifices 21, 21 to control flow rate of fluid by linear action of a valve element 51. Since a pair of orifices 21, 21 are arranged at opposing positions on an inner side face of a valve chamber 23, fluid resistance is not changed even if fluid flows in any direction, which enables stable control of flow rate of fluid. While the valve element 51 closes the orifice 21, fluid pressure is applied to the valve element 51 in the direction crossing the direction of linear action to reduce driving force for letting the valve element 51 act linearly and reduce the size and weight of the control valve 10.

摘要： PROBLEM TO BE SOLVED: To provide an electric valve capable of improving assembly precision of parts constituting the electric valve more than a conventional electric valve.
SOLUTION: In this electric valve 10, since a brazed part of a cylindrical case 14 for an annular sheet metal member 22 and a brazed part of a valve port constituting member 21 are separated from each other, the annular sheet metal member 22 is first brazed to the valve port constituting member 21 to form one part (an end part constituting member 13) and the cylindrical case 14 can be brazed to this one part. Consequently, assembly precision of parts constituting the electric valve 10 is improved more than the conventional electric valve brazing three parts simultaneously, and engagement of a stator engaging part 35 and an overhanging engaging part 22E is stabilized.
