Abstract
A rotary slide valve, in particular for speed-dependent power steering systems in motor vehicles, has a torsion bar, a rotary slide, and a control bushing. The control bushing is pressed onto a pinion and the torsion bar is inserted into a torsion bar bore of the pinion. The control bushing is connected rotation-fast to the pinion by shaping. The torsion bar has teeth that are pressed into the torsion bar bore of the pinion and that connect the torsion bar to the pinion rotation-fast.
