PCT No. PCT/IT96/00015 Sec. 371 Date Jul. 10, 1997 Sec. 102(e) Date Jul. 10, 1997 PCT Filed Jan. 19, 1996 PCT Pub. No. WO96/22463 PCT Pub. Date Jul. 25, 1996Apparatus is disclosed for articulating and correcting the trajectory of a piston in a volumetric machine with a plurality of pistons in a plurality of corresponding curved cylinders. The apparatus includes a piston seal ring positioned in a plane inclined to a plane of rotation of the pistons, with the inclined plane being different for each of the pistons and an intersection point of the axis of rotation of the pistons and an axis of rotation of the cylinders, a position compensation element permitting movement of the selected piston tangential to an instantaneous trajectory of that piston, and a piston support in radial contact with that piston to compensate centrifugal forces acting on that piston.
