GAS-DISTRIBUTING VALVE Russian patent published in 2009 - IPC F16K11/85 F16K5/12 F16K5/04 

FIELD: machine building.

SUBSTANCE: invention elates to machine building and is provided for usage in gas-distributing valves, operating on the basis of combustion materials of rocket fuels and providing control of aircraft in planes of pitch and snaking. Gas-distributing valve contains casing with inlet and outlet branches with delivery outlets located in casing with ability of rotation of shutter connected to shaft. Shaft axis is located perpendicular to axis of delivery outlet of outlet branch. Shutter is implemented in the form of part of hollow cylinder in the form of sector with delivery outlet and is installed relative to shaft and inner surface of casing with radial clearance and jointed to outlet branch. On shaft there are implemented perpendicularly to its axis annular bosses non overlapping located in the same plane delivery outlets of inlet and outlet branches. In annular bosses of shaft there are implemented cuttings. In cuttings there are installed cylindrical limiters with butt-end clearance. The latter are implemented on side surfaces of shutter.

EFFECT: reduction of drain of gas at increasing of reliability of valve operation in conditions of high temperatures and pressures and also providing of thrust reversal.
