Definitions

• the object of the invention is to further utilize this considerable residual energy, that is to say to create an engine in which the intake space and the combustion space are separated from one another and the latter is substantially larger than the former.
• the essential features of the invention result from patent claim 1.
• Fig. 1 shows a section through the motor, perpendicular to the rotor axis
• Fig. 2 shows a section along the line II - II of Fig. 1.
• a rotor 2 seated on the shaft 3 is accommodated, the play between these two parts is kept as low as possible.
• the combustion chambers 5 are - preferably several times larger than the intake chambers 4.
• a spark plug 6 is fitted behind each intake chamber 4.
• the slides 7 and 8 are used to delimit the volumes of intake and combustion chambers which have to be varied periodically during operation.
• the slides are movable in radial grooves of the rotor and are provided with lateral pins 11 which run in groove tracks 9 and 10 of the housing side walls are.
• the groove tracks run concentrically to the rotor axis, in such a way that the course of the track 9 corresponds to the peripheral contour course of the intake spaces and that of the track 10 corresponds to that of the combustion spaces. It is thereby achieved that the slides 7 pass over the suction spaces 4 in an exactly sealing manner, while the slides 8 effect the same in both combustion spaces 5.
• a sealing lip 14 is provided on the rotor, which provides a gas-tight separation between the intake and combustion chambers guaranteed.
• a recess 13 is provided on the rotor circumference between the slides of each pair, which represents the compression space, the size of which is dimensioned such that a predetermined compression ratio results.
• the operation of the engine is explained in more detail below.
• the mixture is sucked in through the movement of the slide 7 and pressed into the compression space 13, then ignited by the candle 6, whereupon the combustion takes place in the space 5.
• the combustion chamber is sealed by the slide 8, on which the tangentially directed driving force is exerted by expanding gases. Since this space 5 is significantly larger than the suction space 4, the energy released during the expansion can be used much further than in normal piston engines.
• the sealing lip 14 prevents the high gad pressure in the combustion chamber from having an effect on the preceding intake space.
• the intake and combustion chambers of the engine units will be arranged so as to be staggered from one another, thereby further increasing the smoothness of the engine. It is clear to the person skilled in the art that the engine can also be designed as a diesel engine.
