ADVANCE-RETARD MECHANISM FOR AXIAL PISTON MACHINE AND AXIAL PISTON MACHINE INCORPORATING SUCH

摘要

A Z-crank axial piston internal combustion engine that includes a cylinder cluster of at least two piston containing cylinders rigidly located with respect to each other. Each cylinder includes at least one working fluid transfer port. A crankshaft is rotatable relative to said cylinder cluster and carries an angled crank about which a recipricator can rotate. It is in mechanical connection with the pistons. A ported member is presented relative to which the cylinder cluster can rotate. The ported member can seal the at least one fluid transfer port of each cylinder yet offer, at intervals, their exposure to spark plug(s) and/or working fluid delivery and removal facilities. An indexing drive controls the relative rotation so that desired range of movement of the piston in each cylinder is timed between TDC and BDC during transfer port exposure. An indexing drive phase controller provides an advance retard facility for the engine.
