摘要： A valve is provided that comprises a valve body including an inlet, an outlet, and a check valve chamber having an opening through the side of the valve body. The valve has a cover secured within the side opening in the valve body. A first valve opening is disposed between the inlet chamber and outlet chamber. A control valve is movable relative to the first valve opening to regulate fluid flow through the first opening when fluid flow is in the inlet-to-outlet direction, and is movable to engage the first valve opening to restrict fluid flow in the outlet-to-inlet direction. The valve comprises a passageway between the inlet and check valve chambers, and a second valve opening disposed between the check valve and outlet chambers. A check valve is disposed within the check valve chamber, and is movable relative to the second valve opening to restrict forward flow and permit reverse flow through the second valve opening.

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 moves in response to changes in the pressures against the first and second sides of the diaphragm, wherein the diaphragm movement allows first valve element to move to regulate fluid flow through the first flow path. 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 when the diaphragm is displaced more than a predetermined distance beyond the closure of the first flow path.
