Expansion valve

摘要

An expansion valve (1), for sensing the temperature change of a refrigerant at an outlet of an evaporator (7) in order to control the flow rate of the refrigerant supplied to the inlet of the evaporator (7) comprising: an expansion valve unit (2), a valve casing (3) and fixing means (4). The expansion valve unit (2) is inserted into the valve casing (3) and fixed thereto by the fixing means (4). The valve casing (3), a high-pressure refrigerant pipe (5) and a low-pressure refrigerant pipe (6) are formed integrally with the evaporator (7).
