ABSTRACT:
A housing mantle or casing produced in a compact construction for a rotary piston engine with a trochoidal-shaped dual-arc mantle runway or raceway and sealing strips arranged in corners of a triangular piston rotating upon an eccentric of an eccentric shaft so that the sealing strips slide along the mantle runway. A layer of steel forming the mantle runway and an outer layer of aluminum alloy is cast around the layer of steel. The layer or band of steel forming the runway has openings with radially outwardly bent-open edges which are cast of filled-out with cast metal forming the outer layer as far as to a plane which coincides with a base plane of the steel layer or band forming the mantle runway.
