A Greek Laboratory, highly specialized in Pure Mechanical Systems, has developed an Innovative Transmission Mechanism with many significant applications.
This Transmission Mechanism (DOT: Distributive Oscillating Transmission) interconnects, in the most effective way, a plurality of Elements with a main Shaft, said Elements and Shaft rotating coaxially around a common axis with different but completely programmable angular velocities.
This interconnection is achieved via planetary systems with some non-circular gears which have almost the same mechanical efficiency as the standard ones.
The Transmission Mechanism can perform literally any required Cycle, Thermodynamic or not, even one with odd number of asymmetrical Strokes, with the greatest possible degree of mechanical efficiency in both directions.
One major application is an advanced Stirling Engine, in two versions: one of high efficiency and a second with lower efficiency, but also with significantly lower cost of construction and maintenance.
Another major application is an advanced Internal Combustion Engine (THE: Toroidal Hermetic Engine) with Three Rotating Toroidal Pistons, performing in the simplest possible way an almost Ideal Thermodynamic Cycle:
-Intake (of pure air-fuel mixture or mixed with exhaust gas, if necessary),
-Compression (up to any required Compression Ratio),
-Combustion (Isochoric, for any required Period, almost exactly or exactly, if necessary),
-Expansion (for any required Period, with Volume, continuously, up to any required multiple of Intake Volume),
-Exhaust (down to any required Volume, even zero Volume, if necessary),
-MetaStathmeusis (with/without cooling/cleaning procedure, for any required Period, or even zero Period, if necessary).
From another point of view, this Internal Combustion Engine could be the main and the most adaptive Platform for a Compact Hybrid Engine.
Other applications are Hydraulic Pumps or Motors, Pneumatic Pumps or Motors, Refrigeration Machines and Electric Generators or Motors.
Significant Advantages are:
-Maximum Mechanical Efficiency,
-Achievement of any required Progressiveness,
-Capability of Stop-and-Start Operation,
-Capability of Very Slow Output without an additional Reduction Unit,
-Achievement of excellent Sealing,
-Capability of Isochoric Combustion,
-Capability of Isobaric Combustion.
Following a specific Research Strategy, more than 20 substantial Parameters (some of them with a number of discrete values greater than two) have been investigated, therefore more than Two Millions of discrete Structural Combinations have been virtually tested one by one.
Among these Structural Combinations there are configurations without peripheral slot, or with shorter or even of zero length cantilever of the body of the Pistons, or with a ratio of working volume to total toroidal volume much greater than the one that appears in this Proposal.
Although the configuration of this Proposal has performed very well in all the aforementioned virtual tests, there are other configurations perhaps much more promising from a practical point of view and the exhaustive investigation of the commercial potential of all these could be the subject of another Project.
There are already Two International Patent Applications (WO/2007/125373 & WO/2009/040588) with excellent Search Reports and Pending Patents. The Laboratory is looking for License Agreement and/or Technical Cooperation Agreement and/or Partners involved in the production of the Mechanism and/or its Applications.
