Abstract
An expansion valveintegrated with a solenoid valve includes a valve bodyand a valve chamberformed inside the valve bodyto which a high-pressure refrigerant is introduced. A valve memberforms a throttle flow path between a valve seat, and controls the amount of refrigerant flowing therethrough. The valve bodyis operated by the movement of a stopper memberof a power elementvia an actuating rod. The high-pressure refrigerant acts on a surfaceof the stopper memberopposite to a diaphragmvia a pressure equalizing passage, a connecting chamberof a solenoid valve, and a pressure equalizing passage. The stopper memberis sealed between the guide member, so that the high-pressure refrigerant does not act directly on the diaphragm.
