  • Hydrostatic axial piston machine of swash plate design with an adjustable swept volume, in particular hydrostatic axial piston pump
    Patent number: 10408199
    Abstract: A hydrostatic axial piston machine includes a housing, a cylinder barrel, and a drive shaft, which are connected together and mounted in the housing so as to rotate jointly about a first axis. The machine also includes a swash plate mounted in the housing so as to pivot about a second axis to adjust a swept volume of the machine. The machine further includes a hydraulic actuating apparatus, which has an actuating piston that delimits an actuating chamber. The machine also includes a regulating valve attached to a flange face of the housing. The regulating valve has connections situated in the flange face that are used to communicate hydraulic fluid to and from the actuating chamber. The flange face is arranged obliquely so as to enclose an angle with the second axis that is greater than 0° and smaller than 90°.
