膨張弁。 A cylindrical valve body having a first flow path, a second flow path communicating with the first flow path via a flow hole, and a sliding hole in the center, and a seal integral with the valve body. A pipe, an electromagnetic coil provided at the top of the valve body to surround the pipe, a magnetic attractor fixed to the yoke of the electromagnetic coil and located above the sealed pipe, and the electromagnetic coil turned on and off. A piston-shaped valve body that slides in a controlled manner within the sliding holes of the pipe and the valve body, and has a communication hole in the center, and a pressure equalization hole with one side opening in the communication hole and the other side opening on the suction element side. and a spring inserted between the valve body and the suction element, and the valve body is provided with an orifice that communicates with the communication hole in the center and has an annular groove on the outer periphery. An expansion valve characterized in that a circular groove is provided on the periphery and communicates with the circulation hole, and the circular groove and the annular groove communicate with each other when the operation is stopped.
