ABSTRACT:
The axial piston machine comprises a case, a shaft and a cylinder block (2), arranged so as to rotate in the case and having a plurality of cylinders (21) with pistons, adapted to slide in said cylinders and connected to piston rods (6) by means of first spherical joints, the piston rods being connected to a sliding plate (7) by means of second spherical joints (63), said sliding plate (7) being supported by a swash plate (8) via a bearing (72). For the connection between a piston rod (6) and the sliding plate (7), the machine further comprises a first driving rotational surface (61) linked to the piston rod (6) and a corresponding second driving rotational surface (71) linked to the sliding plate (7), a clearance being left between said first driving rotational surface (61) and said second driving rotational surface (71) and said surfaces being adjacent.
