Abstract

Heterocentric Distributive Oscillating Transmission mechanism, as a combination of interlaced planetary systems which interconnect a drive shaft (5) and a plurality of elements (1, 2, 3), where each element, being a carrier, bears a planetary shaft (11, 12, 13) on which two planets (11r & 11a, 12r & 12a, 13r & 13a) are fixed and cooperate simultaneously and continuously with a sun (6), fixed either on the mechanism frame (4r, 4a) or on a base (9) rotatable with respect to this frame, and a sun (7), fixed on the drive shaft, some of the used toothings being of variable transmission ratio and called 'odonto-knodaces' and possibly also having stepwise deployment, achieving in any case unlimited progressiveness and precision. Toroidal Hermetic Rotary Engine, as a machine of volume variation, purely rotary and hermetically piston-bearing, consisting of toroidal pistons (1, 2, 3) being interconnected via the aforementioned mechanism, and a hollow toroidal shell (4r, 4a), which has units equally spaced along its periphery with ports to transfer mass and/or energy, each unit being called 'stathmos' (station), where the aforementioned pistons, moving within this shell, perform differentiated travels per each period and form between them consecutively the volumes required by any cycle, thermodynamic, hydrodynamic, refrigerating, or a combination of these, normal or optimized, a kinematic process, called 'meta-stathmeusis' (re-stationing) being added to this cycle, via which a cycle completed at a 'stathmos' is forwarded to the next 'stathmos', while, since each piston has both faces active and the number of pistons is equal to the number of periods of the thus extended cycle, the period performed at one face of a piston is afterwards performed at its other face, so that each period is always performed between two pistons and all periods are performed consecutively between any two pistons, this operation being called 'diadocho-kinesis' (successive motion). An application of this machine and of the mechanism incorporated in it is the internal combustion engine, with a clearly smoother and more efficient operation, especially a version with five strokes rearranged in three periods, with the travel of the expansion phase being an unlimited multiple of the travel of the intake phase, while other applications are electric generators and electric motors, hydraulic pumps and hydraulic motors, pneumatic pumps and pneumatic motors, refrigeration machines and Stirling engines, the last being of exceptional interest.
