Abstract

An axial piston machine for at least one of a pump and a motor operation includes a housing, connection plate, piston drum, and working piston. The connection plate is connected to the housing. The piston drum is arranged on a rotatable drive shaft in the housing interior and defines at least one cylinder bore. The working piston is arranged in a longitudinally displaceable manner in the cylinder bore. The cylinder bore delimits a cylinder space having a changeable volume. The cylinder space is configured to connect to at least one pre-compression space via at least one hydraulic connection. The at least one pre-compression space is defined by a cavity within the connection plate. The cavity is defined by the connection plate and a closing element. The closing element is arranged between the connection plate and the housing interior.
