Definitions
- the present invention represents a novel hot gas engine with two movable pistons, in which one of the two pistons runs in the interior of the other and thus the outer piston is simultaneously the cylinder of the inner piston and the stroke range of the inner piston is centered or approximately centered in the stroke range of the outer piston maintains (delta type)
- This system can be nested as required, combined, simple and double-acting to manufacture, because of the symmetry, free-piston versions are particularly inexpensive to perform, since it is structurally simple to generate an electromagnetic alternating field that can be tapped to the outside or to allow the outer cylinders to oscillate, are perfect dense hot gas motors can be realized, which drive machines, vehicles or generators directly via the movable cylinders.
- ring-shaped or other types of permanent magnets or coils can be integrated in each of the oscillating piston rods alternating voltages can then be induced in the outer containment tube
- At least two nested pairs of an outer and an inner piston which are firmly connected in series, offer immense advantages over all previous Stirhng motors with their crosswise coupling, especially if the chaining is done via at least one hollow piston rod a simple system with 2 identical work cycles can be built up.
- These pairs can be designed particularly well as free-piston engines, since the phase offset can be set in a defined manner via the distance between the outer cylinders and can also be regulated when the load changes by means of a spring preload that can be changed from the outside Double-acting double-acting systems can be produced very compactly.
- a double motor only consists of 3 main assemblies, 2 of which are movable. The two pneumatically separated gas spaces make it possible to work with two different gases as well as coupling processes with internal and external combustion in one engine
- Phase displacement of free piston systems can be defined and regulated. Complete tightness in free piston systems or oscillating cylinders. Complete mass compensation with mutual coupling of piston pairs with 180 degree phase displacement. Free piston springs can all be on the cold engine side
