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

FIELD: engineering industry, aircraft industry.

SUBSTANCE: invention refers to engineering industry, and is meant for controlling aircraft thrust vector in pitch, yaw and roll channels. 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. The latter is formed by two protrusions. Protrusions are made on the seat and have through holes that are coaxial relative to the shaft. Generatrixes of cylindrical surfaces of protrusions are aligned with cylindrical seat surface. Cylindrical regulating element is installed in the seat along cylindrical surface with the possibility of being turned and is kinematically connected to the shaft. Delivery outlet of the seat is rectangular at the point of its contacting the regulating element. Both sides of delivery outlet of seat are perpendicular relative to axis of its cylindrical surface. A groove is made in the regulating element. Groove's section perpendicular relative to its cylindrical surface is formed by radial surface. Extreme points of the latter are located on diametrically opposite sides of cylindrical surface of the regulating element. Radius thereof is , where r - distance between extreme points of delivery outlet of the seat in cross section of the regulating element, and d - cylindrical diametre value of the regulating element.

EFFECT: improving operating reliability of gas-distributing valves operating on hot gas.
