FIELD: engines and pumps. ^ SUBSTANCE: invention relates to space engineering, particularly, to development and operation of jet engine plants of spaceships, namely to the devices designed to re-fuel spaceships in flight. The fuel feed system incorporates tanks containing fuel and oxidiser, fuel feed lines furnished with shut-off valve, a fuel tank pressurisation system comprising high-pressure cylinders communicating via pneumatic lines with the fuel tank gas chambers, shut-off valves, throttling devices, gas pressure regulators and safety valve. Note here that every fuel tank is provided with a looped pipeline connected in between the fuel tank gas chamber and the outlet from the tank liquid chamber, ahead of the shut-off valve arranged on the fuel feed line. Mind here that the aforesaid pipeline incorporates also a pressure difference pickup connected to the valve control unit. ^ EFFECT: higher reliability and longer life. ^ 1 dwg |
