Abstract
In order to additionally develop a conventional steering valve in such a way that it has a simple and economical design and is insensitive to pressure pulsations, a conventional steering valve is additionally developed by arranging at least one essentially coaxial chamber that extends in the shape of an arc and can be charged with hydraulic pressure either directly or indirectly on the input shaft or the output shaft, with at least one piston element that is directly or indirectly connected to the other shaft being arranged in the aforementioned chamber such that it can be moved along an essentially arc-shaped path.
