Pressurized fuel e.g. gas oil, injection device for internal combustion engine, has set of injection tubes, each with anti-vibration unit that has sleeve to modify fundamental resonance frequency at which tube vibrates

摘要

The device has a set of injection tubes (18) for connecting injectors (16) to a common rail (20) and/or an injection pump. Each injection tube comprises of an anti-vibration unit that is constituted of a sleeve (30) to modify the fundamental resonance frequency at which the tube vibrates and/or reduce the amplitude of vibrations of the tube according to the frequency.
