Pump for conveying fluid, particularly fuel, to accumulator injection system of internal combustion engine of motor vehicle, e.g. common rail system, has coupling element coupled with drive shaft for transferring torque

摘要

The pump (100) has a housing (101) and a drive shaft (103) that is partially arranged in the housing. A coupling element (102) is coupled with the housing and is mounted relative to the housing in a rotary manner. The coupling element is coupled with the drive shaft for transferring torque from the coupling element to the drive shaft. The coupling element has a retainer (106) for a drive element, particularly for a belt or a chain. The coupling element is coupled with the drive shaft by a claw coupling (105), particularly an Oldham coupling.
