Device for a steering system of a motor vehicle

A device for a steering system of a motor vehicle for pressing a toothed rack against a drive pinion, the device having a housing and a thrust piece which is mounted displaceably in the housing and which has a circumferential wall which is in contact with the housing, the thrust piece having opposite terminal ends spaced from one another in a displacement direction of the thrust piece, the thrust piece having, on its circumferential wall, chamber depressions which run in a circumferential direction at least in certain portions, each chamber depression being spaced in the displacement direction from each of the terminal ends and delimiting a hollow chamber arranged between the thrust piece and the housing, the chamber depressions being radially recessed into the circumferential wall of the thrust piece such that each chamber depression has a single open end and is directly bounded by portions of the thrust piece on all other sides, the single open end of each chamber depression facing in the radial direction, the circumferential wall having a fully encircling ring-shaped depression interposed, in the displacement direction of the thrust piece, between at least two chamber depressions.
