Abstract: A motor vehicle having a liquid-cooled engine and a hydraulic power steering arrangement has a single liquid reservoir and a single pump which supply coolant both to a liquid-coolant circuit for the engine and to the hydraulic power steering arrangement.

Abstract: A rotating shaft has a ball bearing axially fixed on the shaft with a recess formed in the outer race. A detent device, urged radially toward the recess, cooperates with inclined flanks on axially opposite sides of the recess to produce a counterforce in response to axial displacement of the shaft without generating significant friction caused by rotation of the shaft. The detent device may have a spherical tip received in a conical or groove-shaped recess or it may be a rotatable roller received in a transversely oriented groove in the outer race.

Abstract: In the representative embodiments described in the specification, a cup-shaped clutch drive member, driven by a drive pinion, rotates about an axially displaceable output shaft. Friction disks alternately coupled to the drive member and the shaft are pressed together to actuate the clutch. To apply actuating pressure to the friction disks without requiring excessive shaft motion, a pressure plate is mounted on the shaft and two pressure-generating members, interposed between the pressure plate and the friction members, have facing surfaces which are oppositely inclined with respect to the clutch axis. The pressure-generating member closest to the friction disks is angularly coupled to the drive member while the other pressure-generating member is free to rotate but held axially captive in the drive member.
