摘要
A hydraulic system for an automatic transmission a valve slide longitudinally adjustable in a valve housing between a first axial position and a second axial position such that a plurality of valve seat pockets are selectively brought into operative connection with each other. A control surface of the valve slide, first and second additional control surface of the valve slide and a spring of a parking brake valve are matched to one another such that the total actuating force applied to the slide valve displaces the slide valve to the first axial position when an actuating pressure of the parking brake unit, a pressure signal at the control surface of the valve slide and an additional pressure signal at the second additional control surface of the valve slide are applied.
