Patent ID: 7013791

Claim:
An axial piston machine comprising a case, a shaft and a cylinder block arranged so as to rotate in the case, the cylinder block having a plurality of cylinders with pistons, adapted to slide in said cylinders and connected to piston rods by means of first spherical joints, the piston rods being connected to a sliding plate by means of second spherical joints, said sliding plate being supported by a swash plate via a bearing, wherein for the connection between a piston rod and the sliding plate, the machine further comprises a first driving rotational surface which is fixedly connected to the piston rod and a corresponding second driving rotational surface which is fixedly connected to the sliding plate, said first and second driving rotational surfaces being distinct from the second spherical joint that connects said piston rod to the sliding plate and each one of said driving rotational surfaces being formed by a rotation of a generating line around an axis, a clearance being left between said first driving rotational surface and said second driving rotational surface and said surfaces being adjacent.
