Abstract (en)
[origin: WO2010040163A2] The invention relates to a fuel supply system for heavy oil common rail injection systems for internal combustion engines, comprising a reservoir (1), a primary feed pump (3) for delivering heavy oil from the reservoir (1) to a high-pressure pump (5), said high-pressure pump (5) being connected to a high-pressure accumulator (rail) (6) via at least one high-pressure line (12), said high-pressure accumulator supplying at least one injector (8), and also to a purge valve (9) which is connected to the high-pressure accumulator via a separate high-pressure line (15) to control at least a partial quantity of the heavy oil to be fed back to the reservoir (1) via a return line. The purge valve (9) comprises a valve element (28) which can be displaced between an open and a closed position, a high-pressure connection for a high-pressure line (15) which communicates with a heavy oil high-pressure accumulator (rail) (6), a low pressure connection for a return line and actuators for actuating the valve element (28), the valve seat (29) of the valve element (28) being designed as a sliding seat.
