A rotary slide valve (1) for power steering in motor vehicles contains a rotary slide (2), which is non-rotatably connected to a valve inlet member (4). The control bushing (3) is non-rotatably connected to a valve outlet member (5).The two valve elements are disposed so that they can move coaxially inside each other and can be maximally rotated in relation to each other over the rotational path of a lost motion coupling. The outside of the rotary slide (2) and the inside of the control bushing have control longitudinal grooves (6, 7), which cooperate with one another in order to direct a pressure fluid to and from two working areas of a servomotorThe rotary slide (2) is connected to the valve outlet member (5) by means of a torsion bar spring (9). Manufacture conditional tolerances that can lead to undesirable effects in the driving behavior are compensated for by means of a play-free suspension connection (10).
