Claims

[Claims for Utility Model Registration] (1) Multiple valve holes that are connected to a fluid passage outside the case, have their end faces closed inside the case, and have a shape that applies fluid pressure evenly in the circumferential direction to the surrounding wall. an annular valve body made of a magnetic material, which has a cylindrical fluid flow port inserted into the case, and is mounted so that the valve hole can be opened and closed by sliding on the outer peripheral surface of the fluid flow port; a spring that biases the valve body in the valve opening direction; and an electromagnetic coil that is attached to the outside of the outer peripheral surface of the valve body and drives the valve body against the biasing force of the spring to open the valve when energized. 1. An on-off valve characterized in that a fluid communication port is provided outside the case and connected to a fluid passage other than the fluid passage, and is installed in communication with an internal space of the case. (2) A pair of the cylindrical fluid communication ports are provided on both sides of the closed surface, and a pair of valve holes, a valve body, a spring, and an electromagnetic coil are provided symmetrically corresponding to the pair of fluid communication ports. An on-off valve according to claim 1 of the utility model registration claim. (3) A pair of the cylindrical fluid communication ports are provided on both sides of the closed surface, valve holes are respectively opened in the peripheral wall of the pair of fluid communication ports, and the valve body simultaneously opens each of the valve holes. It is formed of a permanent magnet having a size that closes the valve body and has different magnetic poles at both ends, and a pair of springs are provided to bias both end surfaces of the valve body in opposite directions, and the electromagnetic coil is in a non-energized state. When DC current is applied in one direction, the valve body in the closed position is driven in one direction to open the valve hole of one refrigerant flow port, and when DC current is applied in the other direction, it is driven in the other direction to open the refrigerant flow in the other direction. The opening/closing valve according to claim 1, which is a utility model, and is provided so as to open a valve hole at the mouth.
