VALVE DEVICE, IN PARTICULAR, FOR REFRIGERATING MACHINE Russian patent published in 2017 - IPC F25B41/04 

FIELD: refrigerating equipment.

SUBSTANCE: invention relates to valve device for refrigerating machine, pumping coolant. Refrigerating machine is equipped with condenser and evaporator. Valve device contains inlet, by means of which contained in condenser coolant may be supplied to valve device, three outlets, through which coolant in valve device can be output into evaporator. Valve element is installed with possibility of rotation around axis and with possibility of switching into several positions. First outlet in first position is connected with coolant passage inlet. Second outlet in second position is connected with coolant passage inlet. Third outlet in third position is connected with coolant passage inlet. In fourth position none of three outlets is connected with inlet. Two of three outlets are connected to inlet in fifth position. Valve element comprises adjustment flywheel, which contains plate, rotary-asymmetrical relative to axis. At that, said plate has two grooves, which connect inlet with one of three outlets for coolant passage.

EFFECT: group of inventions is aimed at increasing of coolant distribution efficiency in refrigerating machine.
