EVAPORATIVE VALVE WITH FORCE BALANCING Russian patent published in 2013 - IPC F25B41/04 F16K11/74 

FIELD: machine building.

SUBSTANCE: proposed invention describes evaporative valve (1) containing inlet branch pipe (2), at least one outlet branch pipe (3) and the first and the second valve parts. Inlet branch pipe (2) is meant for supply to it of free-flowing medium in liquid state. Outlet branch pipe(s) (3) is (are) meant for supply of free-flowing medium at least partially in gaseous state to the path. Valve parts are installed so that they can move relative to each other so that their mutual location determines the conditions of free-flowing medium leakage between inlet branch pipe (2) and outlet branch pipes (3). Besides, valve parts are loaded with the force pressing them to one another during normal operation. Evaporative valve (1) includes means for reduction of resultant force acting on the valve parts.

EFFECT: it is easier to move valve parts relative to each other; forces required for bringing the valve into action are reduced.
