The present invention provides a refrigerant switching valve having improved performance of refrigerant switching. The refrigerant switching valve comprises: a valve body (80) moving supported by a periphery of a valve body shaft (71); cases (66, 67) having the valve body (80) positioned inside; an inlet pipe connection part having one end thereof opened to a valve seat (67b), which is installed on each one end of the cases (66, 67), and the interiors of the cases (66, 67) to allow an inlet pipe (68) to be connected thereto; a communicating pipe connection part having one end thereof opened to the valve seat (67b) and the interiors of the cases (66, 67) to allow a communication pipe (69) to be connected thereto; a stator (62) installed in the outer circumferences of the cases (66, 67); a rotor (70) positioned inside the cases (66, 67) to be supported in such a manner where a rotor (70) can be rotated respectively to the same axis of the valve body shaft (71) of the valve body (80); and an idler gear (79) which transmits the rotation of the rotor (70) to the valve body (80) and is supported in such a manner that the idler gear (79) can be rotated around an idler shaft (78) different from the valve body shaft (71). |
