<p>The invention concerns a rotary slide set for a hydraulic steering arrangement with an outer rotary slide and an inner rotary slide arranged in the outer rotary slide, and having in its surface tank grooves, which are, at least in predetermined rotary positions, connected with a low pressure connection, and at least one through-opening in its wall, each overlapping, at least partly, a tank groove. In a rotary slide set of this kind it is desired to avoid jamming between the inner and the outer rotary slides. For this purpose, surface recesses have been made at the remaining tank grooves to serve as balancing areas.</p> |
