Abstract:
PCT No. PCT/EP89/01056 Sec. 371 Date Feb. 21, 1991 Sec. 102(e) Date Feb. 21, 1991 PCT Filed Sep. 12, 1989 PCT Pub. No. WO90/03295 PCT Pub. Date Apr. 5, 1990.A rotary slide valve, especially for auxiliary-power steering devices for motor vehicles, has a rotary slide (2) rotatable opposite a control bushing (1). The control bushing (1) and the rotary slide (2) have guiding longitudinal grooves (3, 4, 7, 8) that work together for directing a pressure agent from a pressure agent source to and from a servomotor. Guiding edges (5 and 10 and 6 and 11) of the guiding longitudinal grooves (3, 4, 7, 8) of the control bushing (1) and the rotary slide (2), working together, are placed parallel with each other. The guiding edges (5, 6) of the guiding longitudinal grooves (3, 4) of the control bushing (1) and the guiding edges (10, 11) of the rotary slide (2) are positioned conically with respect to each other longitudinally. The rotary slide valve is assembled in such a way that the control bushing (1) and the rotary slide (2) are first pushed axially, in relation to each other, into a position in which the characteristic curve of the valve assumes its ideal position in the field of tolerance of the valve's characteristic curve and that the control bushing (1) and the rotary slide (2) then are fastened in their respective axial positions.
