PCT No. PCT/EP93/00750 Sec. 371 Date Sep. 30, 1994 Sec. 102(e) Date Sep. 30, 1994 PCT Filed Mar. 27, 1993 PCT Pub. No. WO93/19971 PCT Pub. Date Oct. 14, 1993A rotary slide valve (1) for auxiliary power steering systems in motor vehicles contains in a valve borehole (5) of a valve housing (2) a rotary slide (4) that is connected with a steering spindle connection (23). In an axial borehole (6) of the rotary slide (4), a control sleeve (7) is guided so that it can be turned by a limited angle. Rotary slide (4) in its axial borehole (6) has longitudinal control grooves (20) that cooperate with longitudinal control grooves (21) on the outer generated surface of control sleeve (7). The inside-located control sleeve (7) is made by means of a non-cutting production process and can thus have relatively small dimensions. With the help of such a process, for example, by means of cold shaping, one can make both the longitudinal control grooves (21) and the control edges of control sleeve (7). The entire rotary slide valve (1) can be made in a very compact fashion as a result of the small dimensions of control sleeve (7).
