EXPANSION VALVE CONTAINING MIXING DEVICE Russian patent published in 2012 - IPC F16K11/04 F25B41/06 

FIELD: machine building.

SUBSTANCE: expansion valve includes inlet hole, at least two outlet holes, each of which is intended for discharge of fluid medium contained at least partially in gaseous state. The first valve component includes at least two valve seats. The second valve component includes at least two gate elements. The latter are moved simultaneously towards valve seats and from them. Displacement device is intended for displacement of gate elements and valve seats. The second valve component and gate elements are connected so that mutual position of the first valve component and the second valve component determines the opening degree of each of the valves. The above opening degree is controlled synchronously, which allows maintaining the required distribution of the flow in outlet holes. Valve components include a part made in the form of disc and containing the above valve seats or gate elements on its surfaces. Valve seats have the shape of through holes in the disc forming the first valve component. Gate elements have the shape of projecting elements on the surface of the disc forming the second valve component located opposite the first valve component. Cooling system is described as well.

EFFECT: possibility of controlling the fluid distribution in two or more parallel flows is provided.
