Abstract
An axial piston machine whose pistons are formed as stepped pistons and which bound a first cylinder space and a second cylinder space, wherein the pistons are driven on the driving side via an axially displaceable driving surface on which they slide in a sliding bearing with a pressure pocket which is connected to the first cylinder space by a passage, is arranged so that the loading of the sliding bearings is reduced depending on the operating condition of the axial piston machine. This is achieved by connecting the second cylinder space to a second pressure pocket on one of the two sliding surfaces by a second passage separate from the first passage.
