FIELD: engines and pumps.SUBSTANCE: invention can be used in internal combustion engine fuel feed systems. Claimed system has fuel tank (2) communicated via booster pump (1) with the inner chamber (3) of high-pressure pump (5). Pump inner chamber (3) is communicated with its working chamber (9) via dispenser (10) and, via bypass valve (16), with drain fuel line (7). In compliance with claimed invention, the pressure of high-pressure pump working chamber (9) filling is adjusted subject to the pump required displacement. This results from communication of bypass valve spring locating chamber (15) via throttling circuit with hydraulic chamber connected via dispenser (10).EFFECT: higher efficiency.10 cl, 1 dwg |
