Abstract

L'invention concerne un ensemble (1), qui sert en particulier d'installation d'injection de combustible pour l'injection haute pression dans des moteurs à combustion interne. Ledit ensemble comprend un distributeur de combustible (2) et plusieurs soupapes d'injection de combustible (3, 4). Chacune des soupapes d'injection de combustible (3, 4) est disposée sur une coupelle (9, 10) du distributeur de combustible (2). Au moins une des soupapes d'injection de combustible (3, 4) est fixée par un étrier de retenue (16) sur la coupelle (9) associée. L'étrier de retenue (16) comporte au moins une partie étrier (17) qui est disposée entre une face intérieure (18) de la coupelle (9) et une face extérieure (19) de la soupape d'injection de combustible (3). Par ailleurs, au moins un élément composite d'amortissement (11) est disposé entre la partie étrier (17) de l'étrier de retenue (16) et la face extérieure (19) de la soupape d'injection de combustible (3). L'élément composite d'amortissement (11) comporte une couche d'amortissement (22) élastiquement déformable. Cela permet donc de mettre en œuvre un désaccouplement amortissant les vibrations et par conséquent réduisant le niveau sonore.
