The invention relates to a hydrostatic axial piston machine with a cylinder barrel and a control surface. A kidney-shaped input connector and a kidney-shaped output connector are configured in a control base. An exhaust chamber is connected with the input connector and the output connector alternately when the cylinder barrel rotates. The hydrostatic axial piston machine may operate as a pump and a motor.
