A housing of a rotary piston internal combustion engine of trochoidal type of construction consists of two side parts and at least one mantle part with dual-curvature mantle runway and a center part between the two mantle parts, which parts are connected by adjustable bolts directed axially as arranged along the radial periphery of the housing. An eccentric shaft passes through the housing and a triangular rotary piston turns upon the eccentric of the eccentric shaft. Clamping rings are provided at each of two ends of the housing. The clamping rings are circular in axial plan view and have a diameter equal to the length of the long axis of the housing and have a transition in radial direction via the housing in a region of the short axis thereof; the clamping rings are connected by adjustable bolts in a region of the short axis of the housing; a disc or cup spring is arranged at one of the two clamping rings and the cup spring is pressed by tensioning of the adjustable bolts by the clamping ring against the end of the housing as well as pressing the housing against the other clamping ring. The cup spring engages against a steel ring introduced in an end of the housing.
