Reciprocating rotary IC engine - has wedge-shaped radially moving pistons activated by expanding gaseous fluid in wedge-shaped chamber in engine housing

摘要

The circular engine housing has wedge-shaped working chambers (5) around its inner circumference, each chamber with a wedge-shaped piston (7). The piston (7) is guided radially into its operating position. The piston head (8) forms a projection on one side of the piston (7), and the area (10) between the chamber (5), the top of the piston (11) and the head of the chamber (12) is rounded. Packingg strips (15,17,18) are located in the chamber wall (13), the top (11) and side face (16) of the piston. USE/ADVANTAGE - The geometry gives improved performance over the conventional reciprocating rotary engine, while retaining its light weight and compact build. Simple and economical to produce.
