とする膨張弁。 The peripheral edge of the diaphragm is sandwiched between the casing and the upper part of the valve body, which has a valve port that communicates the high-pressure passage and the low-pressure passage, and an operating rod that is pressed down by a spring is attached to the top surface of the diaphragm so that it can move up and down. An electromagnetic coil is attached around the movable core while engaging with the movable core in contact with the valve, and a valve that is resilient by a spring that opposes a spring through a diaphragm is attached to the valve port from the high pressure passage side, and the valve and the lower surface of the diaphragm are connected. It is characterized by being engaged by a control rod and communicating the lower surface of the diaphragm with a low-pressure passage through a pressure equalization hole, and by adjusting the amount of current applied to the electromagnetic coil, the load on the movable core pushed down by the spring can be adjusted. expansion valve.
