Description

Designation: VentiWllose-Rctat-Ionssylinder-Machine

in "comprehensive construction" through artificial scarcity, stretching and by strong price increases of fossil energy as well as by upcoming high Investing in alternative fuels is the additional burden on the economy only primarily by reducing general fuel consumption to keep within limits.

A dirigistic measure to reduce it might be ineffective and unsuccessful and can still affect the economy in certain places extreme loads.

In addition to this measure, which must be ruled out, there are others Opportunities to save fossil energy but without sacrificing performance, such as e.g. by optimizing certain areas of drive units and elements etc.

One of these areas to optimize would be the disadvantages of today's Reciprocating internal combustion engine with its low efficiency, its extraordinary high dead weight, due to the crankshaft, camshaft, valve, etc., limited Speed and through the power-sapping permanent acceleration of the piston and connecting rod masses as well as the high friction losses of the pistons.

The invention is based on the task of reducing the general Consumption of fossil and alternative fuels at the same or higher Range of services through optimization of frictional losses, better utilization of Combustion fuels with lower environmental impact, through direct conversion the physical expansion pressure into a torque without eccentric and without force-sapping, permanent acceleration of the reciprocating piston and connecting rod masses as well the reduction of the dead weight.

The object is achieved according to the invention by the establishment of the characterizing Features of claim no. 1 solved.

Optimization of the thermal circumferential expansion in the start and cold phase.

The task is in a generic device by the characterizing Features of claim no. 2 solved.

Pneumatic pressure seal when the compressed gases are advanced.

The task is in a generic device by the characterizing Features of claim no. 3 solved.

Valveless rotary cylinder machine in `` comprehensive design '' for sucking, compressing, expanding of general gases The task is with a generic device by the characterizing features of claim no. 4 solved.

The advantages achieved with the invention are in particular: - no eccentric - absolute symmetrical rotation of the cylinder - compact design (similar to Wankel engine) - through integrated symmetry of the rotating cylinders - 2 x 4 working cycles per 3600 revolutions of the cylinder, which corresponds to 100% Increase in the work cycles per 3600 rotation compared to the conventional reciprocating engine - free design of the combustion chamber (in contrast to the Wankel engine, the ratio of surface area / Volume of the combustion chamber can be optimized, resulting in more favorable exhaust gas compositions given) - no energy-consuming, reciprocating masses such as pistons and connecting rods etc.

- optimal dynamic balancing of the rotating cylinders - no valves, no valve control etc.

- the compression ratio is freely selectable - production-related simple components (the cylinders and the working spaces are rotationally symmetrical Parts) One embodiment in its essential working process is the valveless rotary cylinder machine overall design "is shown in the following drawings and descriptions.
