Abstract
The invention relates to a cylinder drum (1′) for a hydrostatic piston engine, having at least one kidney-shaped control port/cylinder bore transition (5′, 5″, 5″) which leads into a cylinder bore (2, 2′a) for receiving a piston that can be axially displaced therein, wherein the kidney-shaped control port/cylinder bore transition (5′, 5″, 5′″) is configured perpendicular to the flow direction in a stepless and edge-free manner.
