An axial mechanism for converting between linear reciprocating motion and rotary motion comprises a z-crank shaft, a wobble member rotationally mounted to the angled crank pin of the z- crank shaft, and one or more pistons with a connecting rod between each piston and a pivot joint to the wobble member. In one embodiment the connecting rods have sufficient inherent flexibility to accommodate sideways motion in a 360° orbit at the wobble member end of the connecting rod. In another embodiment there is a lubrication communication passage from within the wobble member to each of said pivot joints. In another embodiment each such pivot joint is fitted to the wobble member an integral unit. In another embodiment the z-crank shaft is supported for rotation by bearings all positioned to one side of the z-crank shaft, spaced along the output drive end of the z-crank shaft. In another embodiment a torque restraint member is coupled between the wobble member and a non-moving reference point via a resilient mount or bearing which allows for limited oscillatory and longitudinal movement of the torque restraint member.

L'invention porte sur un mécanisme axial de conversion d'un mouvement linéaire en mouvement circulaire comprenant: un vilebrequin en Z; un élément oscillant monté tournant sur l'axe incliné du vilebrequin; et un ou des pistons dont la bielle est reliée par une articulation à l'élément oscillant. Dans une exécution, lesdites bielles présentent une flexibilité inhérente suffisante pour permettre à leur extrémité couplée à l'élément oscillant des mouvements latéraux sur une orbite de 360°. Dans une autre exécution, un conduit de lubrification relie l'intérieur de l'élément oscillant à chacun desdites articulations. Dans une autre exécution, chaque articulation est une partie intégrante de l'élément oscillant. Dans une autre exécution, le vilebrequin en Z repose sur plusieurs paliers, tous placés de son extrémité menante. Dans une autre exécution, un limiteur de couple est monté entre l'élément oscillant et un point de référence fixe par l'intermédiaire d'une monture ou un palier élastique limitant les mouvements oscillatoires et longitudinaux du limiteur de couple.
