摘要 |
<p>The invention relates to a rotary disk valve (1) for power steering systems of motor vehicles, containing a rotary disk (2) which is rotationally fixed to a valve input element (4). The control bush (3) is rotationally fixed to the valve output element (5). The two valve elements are situated in such a way that they can move into each other coaxially, and can turn as far as possible in relation to each other about the path of rotation of a backlash coupling. The rotary disk (2) has outer longitudinal control slots and the control bush (3) inner longitudinal control slots (6, 7). Said longitudinal control slots (6, 7) interact in order to direct a pressure means to and from two working chambers of a servomotor. The rotary disk (2) is connected to the valve output element (5) by a torsion bar (9). Production-related tolerances, which could have undesirable effects on the handling of the vehicle are compensated by a hung connection (10) with zero play.</p> |
