FIELD: mechanical engineering; engines.
SUBSTANCE: invention is designed for draining fuel leaks from manifold and returning fuel into engine fuel system. Proposed device contain drain tank connected with drain fuel source, ejector with working nozzle, outlet and receiving chamber, drain tank shutoff valve, float installed in drain tank and connected with shutoff valve. Constant pressure valve connected with ejector outlet is installed at inlet of ejector working nozzle. Throttling needle with spring and piston is installed in working nozzle of ejector. One space of piston being connected with drain space and the other, with ejector outlet.
EFFECT: prevention of cavitation in ejector and getting of air into fuel system.
