FUFL NOZZLE FIXING DEVICE

摘要

PURPOSE:To achieve good vibration-proof performance and sealing performance, by supporting a fuel nozzle while holding between an engine member and a rear fuel piping through a seal ring at the tip side and an 0 ring at the rear end side. CONSTITUTION:A fuel nozzle 3 and a fuel piping 4 are provided through a holder 2. The holder 2 is C-shaped while equipped with flanges 5 at the front and rear where insertion holes are made to be inserted with the nozzle 3 while said nozzle 3 is provided with the step sections at the front and rear end sections and small diameter sections 8 with which a front seal ring 9 and rear 0 ring 10 are fitted. The holder 2 is overlapped with the facing face of an engine member 1 and the fuel piping 4 at the front and rear flanges 5 then fastened through each screw 11. Consequently good vibration-proof preformance and sealing performance can be achieved by both rings.
