发明名称 FUEL DELIVERY DEVICE FOR AN INTERNAL COMBUSTION ENGINE
摘要 <p>The invention relates to a fuel delivery device for an internal combustion engine having a housing (1) for accommodating at least one delivery module and a drive shaft (2) for driving the delivery module, wherein the drive shaft (2) is mounted rotatably in a bearing bore (3) of the housing (1), and wherein a sealing arrangement (4) is arranged within the bearing bore (3), comprising at least one shaft sealing ring (5) for sealing a fuel-conducting inner region (6) with respect to a lubricant-conducting outer region (7). According to the invention, the drive shaft (2) has a lubricant path (8) which guides lubricant from radially on the inside to radially on the outside in relation to the longitudinal axis A of the drive shaft (2) as far as the diameter of a sealing contour (9) of the shaft sealing ring (5), which sealing contour (9) bears against the drive shaft (2), with the result that the shaft sealing ring (5) can be supplied with lubricant via the lubricant path (8) during operation of the fuel delivery device, with utilization of a centrifugal force.</p>
