ABSTRACT:
In an axial piston machine of the swashplate or bent axis type having slot control and a pressure balancing passage at the inlet end of the high pressure (HP) control slot, erosion caused by the jet of the pressure balancing passage is prevented by providing at the inlet end of the HP-control slot an interference jet passage starting from the high pressure whose opening is arranged so that the directions of flow of the pressure balancing passage and the outlet of the interference jet passage intersect.
