摘要： The invention relates to a rotary shift valve (1) for servo-assisted steering systems of motor vehicles. Said valve (1) comprises a rotary disc (2) which is connected to a valve input member (4) in a rotationally-fixed manner. The control bush (3) is connected to the valve output member (5) in a rotationally-fixed manner. The two valve elements are arranged coaxially such that they can move within one another and can be rotated in relation to one another about the rotational travel of a backlash coupling. The rotary disc (2) is provided with external longitudinal control grooves (6, 7) and the control bush (3) is provided with internal longitudinal control grooves (6, 7). Said grooves engage with each other for controlling a hydraulic fluid towards and away from two working chambers of a servomotor. The rotary disc (2) is connected to the valve output member via a torsion-bar spring (9). Manufacturing-related tolerances which can create undesired effects of the performance are compensated by a connection element (10).

摘要： The invention relates to a device for pressing a gear rack on a pinion comprising a pressure piece (3) and an adjusting system (4) which comprise bearing surfaces (13a, 7a), which are oriented towards each other and arranged against each other in the normal position thereof, wherein at least one bearing surface is mounted on a spring. The pressure piece comprises a body (6) and a stub (7) which is projected in a direction of the adjusting system and whose free end is used as the bearing surface (7a). The adjusting system (4) consists of two parts, i.e. an adjusting screw (12) and a spring washer (13) which is disposed between said adjusting screw (12) and the pressure piece (3) and consists of a bearing surface (13a) for the stub (7) free end.
