FIELD: engines and pumps.
SUBSTANCE: fuel tank pressurisation system consists of high pressure accumulator and collector of gas consumers, which are connected to each other by means of pipelines with pulse valves and manifold valves, pressure sensors in collector of gas consumers, which are installed in them in series, and control system of pulse valves on trigger principle with fixed pressure levels of activation and deactivation of pulse electric valve; at that, differentiation stage of pressure sensor signal as to rate of pressure increase in collector is introduced in addition to trigger control scheme of pulse electric valves.
EFFECT: stabilising the pressure and enlarging flow characteristics of the control.
