Title (EN) COMMON RAIL ACCUMULATOR CLAMP
(FR) PINCE D'ACCUMULATEUR À RAIL COMMUN
Abstract:
(EN) An accumulator clamp (74) for an accumulator assembly (26) in an engine assembly (20) is disclosed. The accumulator assembly (26) further includes an accumulator body (70) and a fuel line adapter (72) connected thereto, and the accumulator assembly (26) is mountable into a cylinder head accumulator bore (30) of a cylinder head (22). The accumulator clamp (74) includes a clamp body (120) having a clamp accumulator bore (136) receiving an end of the accumulator body (70), and a bolt bore (162, 182) on either side of the clamp accumulator bore (136) for receiving threaded portions of accumulator mounting bolts (46) that secure the accumulator assembly (26) to the cylinder head (22). The bolt bores (162, 182) include bolt slots (168, 188) through the walls of the accumulator body (70) so that the threaded portions of the accumulator mounting bolts (46) are insertable into and removable from the bolt bores (162, 182) through the bolt slots (168, 188) to allow installation and removal of the accumulator assembly (26) without disassembling components of the engine assembly (20) around the cylinder head (22).
(FR) L'invention concerne une pince d'accumulateur (74) destinée à un ensemble accumulateur (26) dans un ensemble moteur (20). L'ensemble accumulateur (26) comprend en outre un corps d'accumulateur (70) et un adaptateur de conduite de carburant (72) relié à ce dernier, et l'ensemble accumulateur (26) peut être monté dans un trou d'accumulateur de culasse (30) d'une culasse (22). La pince d'accumulateur (74) comprend un corps de pince (120) doté d'un trou d'accumulateur de pince (136) recevant une extrémité du corps d'accumulateur (70), et un trou de boulon (162, 182) de part et d'autre du trou d'accumulateur de pince (136) permettant de recevoir des parties filetées de boulons de montage d'accumulateur (46) qui fixent l'ensemble accumulateur (26) à la culasse (22). Les trous de boulon (162, 182) comprennent des fentes de boulon (168, 188) à travers les parois du corps d'accumulateur (70), de sorte que les parties filetées des boulons de montage d'accumulateur (46) peuvent être insérées dans les trous de boulon (162, 182) et retirées de ces derniers à travers les fentes de boulon (168, 188) pour permettre l'installation et le retrait de l'ensemble accumulateur (26) sans démonter les éléments de l'ensemble moteur (20) autour de la culasse (22).
