FIELD: valves.
SUBSTANCE: invention relates to multiple-activation LRE automatic systems, where hydraulically controlled normally open gas valves are widely used, which operate when the operating pressure of one of the fuel components necessary for their closing is reached at the outlet of the fuel pump. In the gas valve, a pressure divider is made, consisting of a channel exiting the control cavity through holes in the stem and an installed throttle washer into the drainage cavity, as well as a throttle device in the inlet branch pipe of the control cavity, consisting of two throttle washers with holes equally spaced from the axis, and installed in the package.
EFFECT: using a hydraulically controlled gas valve in a wider range of control pressures, without manufacturing new parts and assemblies, and its application in rocket engines with high control pressure of the components at the outlet of the fuel pump.
