Abstract: A transmission mechanism via which the kinematic interconnection of a plurality of coaxially rotating bodies is achieved, said transmission mechanism being called a "Distributive Oscillating Ttansmission" mechanism, and a variable - via piston stroke - volume machine, which is built around this transmission machanism, said machine being called a "Toroidal Hermetic Engine". The distributive Oscillating Transmission mechanism consists of a fixed frame, of the moving bodies and of a carrier which bears a planet. The coaxially rotating bodies are supported on the same central shaft via cooperating cages, each of said cages consisting of two discs arranged at a certian distance from one another so as to receive any non-axial torque and interconnected via bars which are parallel to the central axis of the transmission mechanism, said bars having a cross-section in the shape of a part of a circle's sector and being of appropriate number and equally spaced along the disc peripehery, so as to ensure adequate mechanical strength for supporting the bodies and also to allow their unobstructed relative motion in a specific angular travel required for the function of the transmission. The carrier also rotates around the central axis, supporting, at a position parallel to and offset from the cemtral axis, a planet, said planet cooperating, on the one hand, with a gear fixed on the frame of the transmission, thus moving via the relative motion of the carrier with respect to the frame and,on the other hand, with the rotating bodies via a toothing of variable gear ratio called "odonto-knodax" (cam gear), said toothing being deployed spirally both on the planet and on the bars of the rotating bodies, so that the planet cooperates with all the bodies simultaneously and continuously, either distributing to or taking in from the bodies the required power, said planet being called, because of its multiple connections, a "poly-planet". The Toroidal Hermetic Engine consists of a hollowtoroidal shell, of a plurality of pistons, which are parts of a toroid and of the Distributive Oscillating Transmission mechanism, which interconnects the pistons. The shell has units of appropriate number, equally spaced along the shell periphery, each of said units being called a "stathmos" (station) and having ports for the transfer of mass or energy or a combination of both, while the pistons are of such dimensions as to cooperate with the shell, and move with respect both to the shell and to each other, said pistons being appropriately distributed along the periphery, so as to form between them consecuively the volumes required by any thermodynamic, hydrodynamic or refrigeration cycle, while a kinematic process is added to the aforementioned cycle, via which, when a cycle is completed at a "stathmos", the same cycle is forwarded to the next "stathmos", said process being called therefore "meta-stathmeusis" (re-stationing), while, because of the fact that each piston has both facesactive and the number of pistons is equal to the number of strokes of the complete functional cycle and the process of "meta-stathmeusis" (re-stationing), the stroke performed at the piston's rear face is performed afterwards at its front face, so that, on the one hand each stroke is always performed between two pistons, and on the other hand all strokes are performed consecutively between any two pistons, a process which is called "diadocho-kinesis". The piston are supported about the same central shaft via cages, and the "odonto-knodaces" (cam gears) are arranged on the bars of the cages of said pistons, while the introduction of only two more moving parts, the carrier and the "poly-planet", the mechanical interconnection of the pistons and the output or intake of the required power are achieved. One application of this variable volume machine is the internal combustion engine, which has a clearly smoother and more efficient function, while the case in which the carrier is fixed to the stationary frame and the shell forms the drive shaft is of particular interest, since the residual energy of the exhaust gas is also used, via reaction. Other applications of this machine are thje pneumatic or hydraulic motor or pump, but also the refrigeration machines, while the Stirling engine is of exceptional interest.
