ABSTRACT:
An axial piston machine has a rotary shaft, a first group of concentric radially spaced cylindrical bores, and a second group of concentric radially spaced cylindrical bores axially spaced from and aligned with said first group of cylindrical bores. A wobble plate is located between the groups of cylindrical bores and is positioned at an angle relative to the axis of rotation of the rotary shaft and is connected to said rotary shaft. A piston is located in each pair of cylindrical bores for reciprocal movement, and each piston includes two axially spaced piston segments and a bridge segment connecting the piston segments and attaching the piston segments to the wobble plate. Each bridge segment has a guide which is effective in the peripheral direction to contact a corresponding guide on adjacent bridge segments to prevent rotation of the pistons.
