、冷媒流を閉止する事が不可能となる欠点があった。Conventional structure and its problems Conventionally, this solenoid valve, which has been commonly used in refrigeration equipment, has an imamomoto structure consisting of a cylinder (a), a mover ←) and an electromagnetic coil (c), as shown in Figure 1. The passage of the refrigerant through the refrigerant stop 1 was controlled by moving the movable element (b) up and down for the refrigerant flowing into the inlet vibrator. However, in a refrigeration system using a compressor, fine iron powder is generated from the sliding parts inside the compressor, and this iron powder can cause trouble at various locations in the refrigerant circuit. A solenoid valve clearly shows this, and as shown in Figure 1, if iron powder adheres between the valve seat (E) of the main body and the pole at the tip of the mover (B), the refrigerant flow will be interrupted. It had the disadvantage that it was impossible to close it.
