<p>The axial thrusts applied to two rotatable slide valve elements of a steering control valve assembly, are transmitted independently of each other through radially overlapping, anti-friction bearings to a common axial thrust absorbing surface. A thrust transmitting spacer positioned radially inwardly of one of the anti-friction bearings, extends axially between the other of the anti-friction bearings and the thrust absorbing surface.</p> |
