In the time of heating-operation, a refrigerant flows into a valve case 2 through a part 3a on the side of an indoor unit and passes the check valve 20, and the flow thereof is regulated by both a valve member 6 and a valve seat port 19. Then the refrigerant flows to the side of a port 3b on the side of an outdoor unit and the flow thereof is controlled by a temperature-sensing tube 9. At this time, since a bypass part 18 on a fixed seat 17 is depressed on the side of the seat 17 by a coil spring 14, it is closed. In the time of cooling-operation, the refrigerant flows through the port 3n on the side of the outdoor unit, and the flow pressure thereof lifts a seat 16 on the bypass part 18. After that, the refrigerant passes a communicating port 15 on the seat 16, flows in a valve chamber 4a, and flows to the side of the port 3a. Therefore, a check valve provided in parallel with an expansion valve conventionally provided is unnecessary.
