Abstract: In a damping valve for pressure medium-actuated operating circuits, a spring element is installed between housing, cover and counter-contour. In the opening direction, the spring element is pressed against the counter-contour by the pressure medium flowing through, so that a flow passage cross-section allowing almost unimpeded passage of the pressure medium is obtained. In the opposite direction, the throttling direction, the spring element rests on the cover and blocks the flow of the pressure medium until a well-defined pressure builds up, which lifts the inner side of the spring element from the counter-contour and thus opens a reduced flow passage cross-section.

Abstract: A rotary disk valve for motor vehicle power steering systems includes rotary disk which is connected non-rotatably to a valve inlet element. A control bushing is connected non-rotatably to a valve outlet element. These two valve elements are disposed so that they are coaxially movable into one another and are rotatable by at most the amount of torsion of a dead travel coupling. The two valve elements have longitudinal control grooves, which interact with one another for controlling a pressure medium to and from two working areas of a servo motor and to a return connection for a pressure medium container. The rotary disk is connected via a torsion bar spring to the valve outlet element. The longitudinal control grooves of the radially internal valve element connected to the return connection are connected to an internal space of the radially internal valve element. The torsion bar spring is supported in this internal space via a roller bearing. The return from the inner space of the radially internal valve element to the return connection occurs through the roller bearing and through the dead travel coupling.

Abstract: 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 servomotor The 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).
