摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing costs of an expansion valve by increasing the manufacturing efficiency of a body and improving yields from materials. SOLUTION: In the expansion valve, a body 2 is formed by die-casting an aluminum alloy, and the body 2 can be manufactured easily even in a complicated shape. Even a valve seat, which is difficult to form by extrusion, can also be formed integrally to thus enhance the manufacturing efficiency of the body 2. Component parts, such as the valve seat, conventionally formed by cutting, can also be formed integrally by die casting to thus enhance yields from materials and reduce the manufacturing costs of the expansion valve.

摘要： PROBLEM TO BE SOLVED: To provide an expansion valve having low cost without adding other parts for a vibration damping means.
SOLUTION: A plate spring 24 constituting the vibration damping means is integrally formed on a center disc 22 of a power element 13. A radially outward load is applied to the inner wall face of a cylindrical portion 26 formed at the center of a lower housing 20 to generate sliding resistance to the axial movement. By giving vibration damping function to the center disc 22 necessary for constituting the power element 13, the function is increased without increasing the number of parts. Thus, cost for the highly functioning expansion valve is reduced and its assembling efficiency is improved with the less number of parts.

摘要： PROBLEM TO BE SOLVED: To provide an expansion valve capable of correctly transferring heat to a power element, and adjusting the time constant without increasing the cost.
SOLUTION: An equalizing hole 13 is communicated with an equalizing chamber adjacent to a low pressure passage between connection holes 22 and 23 of a valve case 3 immediately below a diaphragm 6 of a power element 1 in a direction orthogonal to the refrigerant flow direction of the low pressure passage. The equalizing hole 13 is formed by cutting out the outer circumference of a holder 12 to be welded to an opening edge portion of a lower housing 5, and the opening area is set according to the time constant to be temperature-sensed by the power element. Since refrigerant in the low pressure passage directly passes through the equalizing chamber via the equalizing hole 13, the power element 1 can correctly sense the temperature of the refrigerant, and the time constant to be temperature-sensed by the power element can be easily adjusted only by changing the opening area of the equalizing hole 13.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of an expansion valve by improving efficiency in manufacturing a body, and improving material yield.
SOLUTION: The expansion valve can be easily manufactured even if the body 2 is of complicated shape because the body 2 is formed by die-casting an aluminum alloy, and material yield is also improved. Further, since a power element 3 and an adjusting member 16 are fixed to the body 2 by caulking a part of the body 2, there is no need to machine thread parts at the body 2, power element 3 and adjusting member 16 to fix them, and machining is simplified. As a result, the manufacturing cost of the expansion valve can be reduced.
