Abstract

An expansion valve unit having a pressure detecting function includes a supercooling control expansion valve disposed in a flow path of a refrigerant sent into an evaporator of a refrigeration system constituting a refrigerating cycle to control the flow rate of the refrigerant. A pressure detector is provided at one end of the supercooling control expansion valve to detect the pressure of the refrigerant sent thereto through a passage in the expansion valve. The supercooling control expansion valve and the pressure detector are integrated with each other by a joining means.
