Abstract:
1. A rotary slide valve for servo-assisted steering systems of motor vehicles, having an input element and an output element supported by means of a torsional spring and coupled to said input element with a limited rotational angle, and, fixed in terms of rotation to one of said elements, having a rotary slide and a control sleeve which, lying coaxially to one another, are provided with crossflow openings whose degree of congruence can be varied as a function of the rotational angle between the rotary slide and control sleeve and of which the control sleeve has an axial region which engages radially outwardly over the output element, said output element bearing a radial coupling pin which, inserted into a receptacle of the control sleeve, is held in the latter, tensioned by a spring, the receptacle, starting from an entry cross section of excess dimensions in relation to the coupling pin, tapers axially to a cross section region which is smaller than the cross section of the coupling pin, and the coupling pin is clamped into a position without play in the tapered cross sectional region of the receptacle, wherein the coupling pin is clamped axially by a spring ring which extends in the peripheral direction of the control sleeve and is assigned a clamping bevel.
