Abstract
A fuel injection pump having a pump-and-distributor member driven by a drive shaft via an Oldham coupling. The Oldham coupling has a cross disk with four arms protruding at right angles from one another. In each of the arms, one roller is supported rotatably as a roller body about a radial axis. On the drive disk and the eccentric disk, one pair of claws is mounted, offset from one another by 90.degree.. With these claws, the drive shaft and the eccentric disk, when the Oldham coupling is mounted, engage the interstices between the arms and the cross disk. The engagement is such that the claws each rest axially movably but practically without play on the rollers of the cross disk. In operation, the friction and noise of the Oldham coupling are reduced.
