Description

7, 8 close together. It is driven by a gear 11 via a pinion 12 which is actuated by an axially displaceable rack 13. The rack 13 is controlled by centrifugal weights 14 depending on the speed. The gear 11 is cardanically connected to the control body 4 via connecting pieces 15.

The P-V diagram according to FIG. 4 shows the simplest Work sequence of the rotary piston internal combustion engine, with constant pressure combustion in the combustion chamber 9 takes place after in the compressor

compression has taken place. After the constant pressure combustion the relaxation can take place in the relaxer.

F i g. 5 shows a P-V diagram for the highest output, with constant pressure combustion in the combustion chamber 9, a recompression, if necessary, with continuous combustion in the expansion tank and then a partially constant-space or approximately constant-space combustion and, if applicable a further combustion takes place in the expansion chamber as the space increases.
