Date Aug. 22, 1996A rotary slide steering valve (1) for supplying an actuator with hydraulic pressure, has an input shaft (2), an output shaft (3), a centering spring element (4) connected to the input shaft (2) and to the output shaft (3) and a valve element. The valve element comprises at least two elements that can be turned relative to one another and comprise control bores for supplying and returning a hydraulic medium as well as a hydraulic medium line to and a hydraulic medium return line from both sides of the actuator. All control bores of the valve element which are assigned to one another are exclusively arranged within a region of opposing end faces of the input shaft (2) and the output shaft (3) and directly connected to pressure medium connections on a housing side of the rotary slide steering valve. The input shaft (2) and the output shaft (3) comprise a disk-shaped widening (11, 12) within the region of the opposing end faces. Control recesses (15, 16, 17, 18) are arranged on the opposing end faces. The axial bores (13, 28, 29) are arranged in the opposing end faces.</p> |
