FIELD: engines and pumps.
SUBSTANCE: liquid-propellant rocket engine contains a chamber, a gas generator, pumps, fuel supply pipelines, starting valves, control gas supply pipelines, the electropneumatic valve, the valves tees with inlet unions for control gas, the control working body inlet, an the control gas and the working body outlet are installed in the control gas supply pipelines, between input branch pipes for the control working body of valves tees and fuel supply pipelines downstream the pumps the control working body pipelines are installed. In the valve tee housing the seat from the side of the control gas supply is made, the adapter with the seat from the side of supply of the control working body and the gate with fluoroplastic seal interacting with seats are installed.
EFFECT: design simplification and weight decrease.
