摘要： A thermostatic expansion valve is provided comprising an inlet, an outlet, first and second flow paths through the valve, a first valve element in the first flow path between the inlet and outlet, and a movable diaphragm having a first side acted on by a first fluid pressure and a second side acted on by at least a second fluid pressure. The diaphragm is movable to permit increased flow through the first flow path when the force against the first side is greater than that against the second side, and is movable to restrict flow through the first flow path when the force against the first side is less than that against the second side. The diaphragm moves in an upward direction to cause the first valve element to close the first flow path, and may continue to move in the upward direction to cause a second flow path to open.
