<P>PROBLEM TO BE SOLVED: To create a new-type fuel supply device for an engine, namely, an improved common-rail type fuel supply device. <P>SOLUTION: An accumulating system is connected to an injector via a high-pressure fuel duct 2 intermittently put under high pressure according to injection timing. The high-pressure fuel duct 2 is provided with a switching device 1. The fuel supply device controls to release either the high-pressure fuel duct 2 or an outflow duct 8 and to block the other by avoiding the switching device 1 and by a closing piston 4. <P>COPYRIGHT: (C)2010,JPO&INPIT |
