<p>The rotary disc valve (10), especially for hydraulic servo steering systems in motor vehicles, has a rotary disc (14) rotatable around a common longitudinal axis inside a control sleeve (12). The rotary disc and control sleeve have several control edges (18,24) with each control edge of the sleeve forming a control gap (26) with the nearest control edge of the rotary disc. Adjacent control gaps of inlet openings (15) for hydraulic fluid from a control geometry. The rotary disc has at least two different control geometries.</p> |
