Abstract

An electric expansion valve includes a drive unit, an output shaft, a main body, a valve body, and a joint portion. The drive unit receives supply of electric power and generates drive force to rotate and translate the output shaft. The main body includes a first inflow/outflow port, a second inflow/outflow port, a valve chamber, and a valve seat. The valve chamber is disposed in a refrigerant passage connecting the first inflow/outflow port and the second inflow/outflow port. The valve seat is disposed inside the valve chamber. The valve body is disposed within the valve chamber to open and close an opening of the valve seat. The joint portion connects an end of the output shaft and the valve body to be integrally displaceable.
