A variable split displacement ratio axial piston machine, featuring a rotatable driveshaft, a tapered swashplate disposed around said rotatable driveshaft, a first working section disposed on a first side of the tapered swashplate, and a second working section disposed on a second side of the tapered swashplate. Each working section includes a respective set of pistons slidably received in a respective set of cylinder bores to draw and expel fluid into and from said cylinder bores. The first and second working sections respectively interface with first and second outer faces of the tapered swashplate in respective first and second facial planes. Tiltable adjustment of a working position of the tapered swashplate is operable to adjust respective orientations of the facial planes, which dictate relative piston stroke lengths of the piston sets. Such tiltable adjustment imparts control over a variable split displacement ratio between the working sections.
