A diaphragm storage chamber that accommodates a diaphragm, a low pressure chamber that includes a needle valve connected to the diaphragm via a valve stem, its valve seat, and a return spring, and a high pressure side connection section that is connected to the discharge side of the needle valve seat. In the automatic expansion valve, a small hole is formed to communicate the diaphragm storage chamber and the high-pressure side connection part, and a check valve is formed in the small hole to prevent the flow of fluid in the direction of the diaphragm storage chamber. Automatic expansion valve characterized by:
