THREE-WAY CONTROL DISTRIBUTING VALVE Russian patent published in 2006 - IPC F16K11/07 F16K27/04 

FIELD: valving.

SUBSTANCE: valve comprises sectional housing with inlet and outlet branch pipes mounted from its both sides, seat, and valving member with control mechanism that provide reciprocation of the valving member. The sectional housing has one outlet branch pipe, seat with inner ring surface, and inlet branch pipe that is connected from one side by means of a flange. From the other side, the first housing is connected with the second housing through the insert. The second housing has the other outlet branch pipe, dummy seat with inner ring surface, and cantilever for control. The insert is made of a ring with side longitudinal grooves. The ring receives the cylindrical valving member with outer face sections and is sealed from both sides by means of seals. The outer surface of the cylindrical valving member is provided with grooves for receiving the half-axles. The half-axles are interconnected through the levers with the control mechanism. The control mechanism causes the cylindrical valving member to move from one end position to the other for permitting pressure-tight contact between the surface of the appropriate seat and one of the face sections of the cylindrical calving member when it is in one of the end positions.

EFFECT: enhanced reliability and reduced power consumption.
