摘要:
To provide an expansion valve which permits both the assembling cost and the cost of parts to be effectively reduced by a large margin and thus is highly economical. A high-pressure refrigerant pipe, a valve casing and a low-pressure refrigerant pipe are previously formed integrally with an evaporator. At the time of assembling, an expansion valve unit having a minimum function to serve as an expansion valve is inserted into the valve casing and fixed thereto by a clip, and a distal end portion of a temperature sensing cylinder is fixed to an outlet pipe of the evaporator, thereby constructing an expansion valve. No special joints are required to connect the expansion valve unit to the high-pressure and low-pressure refrigerant pipes, and therefore, the cost of parts can be cut down. Also, since the valve casing into which the expansion valve unit is fitted is formed integrally with the high-pressure and low-pressure refrigerant pipes and the evaporator, no pipe connection is required, thus reducing the assembling cost.
