Abstract
A hydrostatic axial piston machine includes a pot-like housing, a connection plate that closes the pot-like housing, a rotatably mounted cylinder drum, and pistons arranged in cylinder chambers of the cylinder drum. The cylinder chambers are each alternately connected via a cylinder chamber opening to a low-pressure control opening and a high-pressure control opening of a resting control part. The control part has two switching regions located between the low-pressure and high pressure control openings. A piston reverses its movement direction in a dead center within the two switching regions. In the switching region, the cylinder chambers are connected via a connecting line to a fluid volume arranged in the housing. The fluid volume extends between the connection plate and the housing such that it is sealed to an interior by the connection plate and the housing.
