Rotary piston engine for automotive, agricultural, marine industries has a housing with a supplementary piston

摘要

A rotary piston engine has a housing (4, 5) with a supplementary piston (9, 11). The main rotor (1) has additional curved bodies (3). The piston heads (9, 10, 11) have inclined surfaces. The presence of a supplementary piston and additional curved bodies within the motor distributes the work cycle processes between two pistons working in parallel. The presence of two inclined surfaces on the piston heads optimises their transposition with respect to the curved body, and provides a good seal to the chamber.
