Abstract
The invention relates to a rotary slide valve (1) of servo-assisted steering systems for motor vehicles that comprises an input and an output element (3, 4), which can rotate in relation to one another around a limited angle of rotation, and comprises a coupling connection (10) of the output element (4) to a control slide (7). A torque-transmitting, non-distorted coupling connection (10) between the control slide (7) and the output element (4) is provided by a coupling pin (10), which is fixed inside the output element (4) and radially extends into a seat of the control slide (7). The seat axially tapers to a cross-section that matches the cross-section of the coupling pin (10), whereby it is easy to insert the coupling pin (10) into the seat and possible to attain a play-free supporting position for the coupling pin (10) by axially displacing the output element (4) or the coupling pin (10) and control slide (7) in relation to one another.
