GAS-DISTRIBUTING DEVICE Russian patent published in 2007 - IPC F16K11/02 F02K9/80 F16K31/42 

FIELD: flight vehicle control system, in particular, gas-jet systems, designed for control of rockets and jet projectiles.

SUBSTANCE: the gas-distributing system has an electromagnet, gas power amplifier, type "nozzle-shutter", with inlet and outlet throttle valves, and a power cylinder with a piston a cylindrical hole is made in the piston. This hole passes through the center of the piston perpendicularly to the longitudinal axis. A spherical stem of the rotary valve is positioned in the mentioned hole. The working surfaces of the rotary valve are made cylindrical, and their axes are inclined at an angle to the longitudinal axis of the valve. The inlet and outlet throttle valves of the power amplifier have different diameters. The ratio of the inlet throttle valve diameter to the outlet throttle valve diameter is at least 0.727.

EFFECT: provided maximum power of the gas-distributing device due to selection of rational designed parameters.
