Abstract

La présente invention concerne un injecteur (1) servant à l'injection de carburant. Cet injecteur (1) comprend un dispositif de compensation (7, 13, 19, 20,23) destiné à compenser une onde de pression produite lors de l'injection. Cette onde de pression est ainsi compensée entièrement et de manière fiable par ce dispositif de compensation.
