<P>PROBLEM TO BE SOLVED: To enable to reduce impulse wave and pulsation pressure generated with accompanying open and close of an injection nozzle and enable to reduce generation, transmission, propagation and radiation of noise in high frequency zone, and enable to connect and arrange a socket easily and surely to a connection pipe in a vertical direction. <P>SOLUTION: A fuel delivery pipe is provided with a flexible absorber wall surface on a wall surface, has a plurality of communication openings 17 opened thereon, and is provided with a plurality of sockets 18 projectingly provided with crossing a communication pipe 1 and communicating to a fuel passage 19 via the communication opening 17 of the communication pipe 1 at one end and connecting to a rear end of an injection nozzle 23 at another end. An inner diameter of a fuel flow in opening 28 provided on one end in a communication pipe 1 side of the socket 18 is formed double or more of an inner diameter of a fuel supply hole 30 on an injection nozzle 23 rear end. An engagement flange 21 is provided on one end outer circumference surface of the socket 18 projectingly in a radial direction, the engagement flange 21 is engaged and fixed in a wall surface inside of the communication pipe 1 and is arranged to have another end side of the socket 18 projected outward of the communication pipe 1 via the communication opening 17. <P>COPYRIGHT: (C)2007,JPO&INPIT |
