Abstract
A hydrostatic piston machine having a cylinder block with several cylinders, in which are slidably mounted pistons in load engagement with a reaction member via transmission members, each transmission member is connected to at least one of the piston or the reaction member via a spherical joint comprising a ball recess and a ball pivot comprising a convex spherical surface. The ball pivot has an ending rotational surface which is continuously connected to the convex spherical surface, created by rotating a continuous generating line around the axis of symmetry of the ball pivot, or at least one of the ball recess or the ball pivot has an end wall which is deformable under the loads acting on the spherical joint, so as to provide for an ending rotational surface having a curvature which is different from an initial curvature thereof.
