HOT GAS GAS-DISTRIBUTING VALVE Russian patent published in 2009 - IPC F16K5/04 F16K5/12 

FIELD: engineering industry, aircraft industry.

SUBSTANCE: invention refers to engineering industry, and is meant for controlling aircraft thrust vector in pitch, yaw and roll planes. Hot gas gas-distributing valve consists of a body with inlet and outlet branch pipes, and a seat with delivery outlet and a support assembly. Seat is installed in outlet branch pipe and made from molybdenum tungsten alloy containing copper. Support assembly is formed by two protrusions. The latter are provided on the seat on both sides from its delivery outlet and have through holes that are coaxial relative to the shaft. Generatrixes of cylindrical surfaces of those holes are aligned with cylindrical seat surface. Cylindrical damper is installed inside the seat with a radial clearance along cylindrical surface with the possibility of being turned and is kinematically connected to the shaft. On cylindrical surfaces of protrusions located on the seat and contacting the damper there provided throughout the thickness of protrusions are grooves that are uniformly located and have the same depth. Grooves do not cross the seat delivery outlet.

EFFECT: reducing hinge moment value of gas-distributing valve.
