Abstract
A hydrostatic axial piston machine utilizing a swashplate design has a cylinder drum () that is mounted so that it can rotate around an axis of rotation (). The cylinder drum () is provided with cylinder bores (), in each of which a piston () is mounted so that it can be displaced longitudinally. The pistons () are each supported on a swashplate () by a sliding element (). Between the piston () and the cylinder bore (), there is at least one annular groove () which is located in the area of the inner half (L) of the guided length (L), such as the minimum guided length (L) of the piston () in the cylinder bore ().
