Abstract

In order to avoid output-restricting mass movements, a cylindrical piston, supported so that it oscillates on a crank disc, is so arranged in a pivotally mounted combustion chamber, the axis of which is offset in relation to the axis of the crank disc, that on rotation a variation in the volume of the combustion chamber is bound to occur and the parts can be manufactured without special machine tools.

Explosion engine, especially rotary piston engine

The invention relates to a rotary piston engine in which all relevant parts in connection with the power generation are in rotating motion and the combustion chamber has a cylindrical shape.

Rotary, circular or reciprocating engines are known. Past all have the disadvantage of either Parts accelerated by the explosion (e.g. pistons) at the height of their acceleration a Have to experience change of direction, which leads to a honing loss of power, or the combustion chambers have rectangular waste, which is associated with major sealing problems, or the manufacture of pistons and combustion chambers requires special machining equipment.

The invention has the task of creating an explosion = motor in which the mainly The parts involved in power generation are constantly in circular motion, the combustion chamber of which is a has a cylindrical shape and can be produced without special processing machines.

The solution to the problem with the invention consists in let a pendulum mounted on the bolt of a crank disk, cylindrical piston slides in a cylindrical, rotatably ge = mounted combustion chamber, the axis of which is to the axis of the Crank disc is offset.

By rotating the working shaft 2b by hand or starter machine in the direction of travel, dj.e Crank disk 2 and the piston pin 2a, then via the piston 4, which is pivoted on the piston pin 2a Combustion chamber K set in rotary motion. The piston 4, which in turn is slidably mounted in the combustion chamber K, is displaced the rotary chamber K inevitably rotates around the axis 3. Due to the networked arrangement of the Working shaft 2b to the axis 3 of the combustion chamber K is created in the interior of the housing 1 and in the combustion chamber K inevitably a 70'lumen change, i.e. a sub * - or overpressure. A cam plate 6 fastened on the axis 3 controls the valve piston 5 of the inlet port E. and so determines the opening and closing times of the inlet port E '. That by the negative pressure in the housing = inner fuel-air mixture sucked in via the inlet opening E now passes through with further rotation the overflow slot Ü into the combustion chamber K and is compressed with further rotation until the position of Fig. I (position of highest compression).

The compressed fuel-air mixture is now caused by a spark on the spark plug Z, which its Electricity via a sliding contact gets ignited.

The

The forces released by the explosion act on the piston crown of the piston 4, which in turn is mounted pendulum on the piston pin 2a and offsets the crank disk 2 and the working shaft 2b firmly connected to it due to the staggered arrangement of working shaft 2b and axis 3 of the Combustion chamber K in a rotary motion. The rotation of the combustion chamber K about the pivot point of the axis 3 is inevitably brought about by the piston 4, which is slidably mounted in the combustion chamber K. The fuel-air mixture flowing through the overflow slot Ü into the combustion chamber K, after ignition and expansion, passes through the outflow slot into the open air or into the silencer. The individual cycle sequences correspond to the principle of the "two-cycle", ie during a full rotation of 3t> 0 degrees "work / exhaust" - "on = flow / compress". The process now repeats itself over and over again and sets the motor in constant rotation.

The 'lubrication is done by adding lubricating oil in the fuel. The cooling takes place on the fuel-air mixture inside the housing 1 or by means of water = flowed through cavities.

The advantages achieved by the invention are ins = special in the fact that all parts connected with the achievement of power, with the exception of the slight pendulum movement of the piston 4 are in absolute circular motion. That means that a volume = change in the combustion chamber K and inside the housing takes place without performance-inhibiting movements of Masses also result from the cylindrical shape of piston 4 and combustion chamber K no sealing problems whatsoever and the same are without special processing ^ = machines can be produced.
