Abstract (en)
A cam profile for a hydrostatic radial piston machine comprises lobes arranged in a circumferential direction, each lobe comprising a lobe portion of rising type and a lobe portion of falling type, wherein as the cam profile extends in a circumferential direction, its radial dimension mostly increases in each portion of rising type, and mostly decreases in each portion of falling type; the shapes of at least two lobe portions of the same type are different.
