ROTATIONSKOLVFORBRENNINGSMOTOR

摘要

A rotary piston internal combustion engine with one or more rotary pistons on an eccentric and with a common combustion chamber fixedly connected to the engine housing and communicating through two conduit systems with working chambers. Each of these conduit systems has a mouth in those housing end walls which are located adjacent the respective adjacent piston end faces, and more specifically in the vicinity of the sealing strips between an inner axial seal and an outer axial seal, each of the two conduit systems also including transfer passage means provided in the pistons. The transfer passage means have a smaller flow cross section than the inlet and outlet means of the piston or pistons and respectively comprise a mouth opening within the region of the periphery of the piston or pistons without inlet and outlet control opening as well as on an end face of the piston or pistons. The path curve of the mouth openings at the end faces of the piston or pistons extend radially outside the inner axial seal and moves successively over the mouth openings of the two conduit systems in the side walls of the engine housing.
