Title (EN) BEARING ARRANGEMENT
(FR) SYSTÈME DE PALIER
Abstract:
(EN) The bearing arrangement for a common rail fuel injec- tion pump of a piston engine is configured to carry ra- dial forces and comprises a housing (1), a bearing el- ement (2) that is arranged within the housing (1) and provided with a sliding surface (3) for supporting a ro- tating journal (6) or shaft (7), at least one oil feeding port (4) opening onto the sliding surface (3) of the bearing element (2), and an oil supply bore (5) that is arranged in the housing (1). The arrangement further comprises an oil groove (8) that is arranged between the housing (1) and the bearing element (2) for estab- lishing fluid communication between the oil supply bore (5) and the oil feeding port (4).
(FR) L'invention concerne un système de palier pour une pompe d'injection de carburant à rail commun d'un moteur à piston, lequel système est configuré de façon à supporter des forces radiales et lequel comprend un boîtier (1), un élément palier (2) qui est disposé dans le boîtier (1) et qui comporte une surface de coulissement (3) pour porter un tourillon (6) ou un arbre (7) rotatif, au moins un orifice d'alimentation en huile (4) débouchant sur la surface de coulissement (3) de l'élément palier (2), et un trou de fourniture d'huile (5) qui est agencé dans le boîtier (1). Le système comprend en outre une rainure d'huile (8) qui est agencée entre le boîtier (1) et l'élément palier (2) pour établir une communication fluidique entre le trou de fourniture d'huile (5) et l'orifice d'alimentation en huile (4).
