<P>PROBLEM TO BE SOLVED: To provide a new type fuel supply device for an internal combustion engine, that is, to provide a new type common-rail fuel supply device. <P>SOLUTION: In the fuel supply device, an opposed end part of a single or each high-pressure fuel pipe 10 constantly under high pressure and connecting a pump device with an accumulation mechanism 13 is connected with the pump device or the accumulation mechanism 13 through a connecting part, and/or an opposed end part of a single or each high-pressure fuel pipe intermittently under high pressure and connecting the accumulation mechanism with an injector is connected with the accumulation mechanism or each injector through a connection part. In this connection, a first sealing member is disposed among a cover part of each high-pressure fuel pipe and the connection part, and a second sealing member surrounding the cover part of the high-pressure fuel pipe from a radially outside is disposed between the cover part and an adjustment screw screwed to the connection part. <P>COPYRIGHT: (C)2009,JPO&INPIT |
