Abstract
An engine housing includes a rotor housing and a side housing assembly. The rotor housing includes a rotor housing body. The rotor housing body extends about an axis to form a rotor cavity of the engine housing. The rotor housing body extends between and to a first axial end and a second axial end. The side housing assembly includes a side housing body, a side plate, and a seal assembly. The side housing body is disposed at the first axial end. The side plate is disposed axially between the rotor housing body and the side housing body. The side plate includes an inner side, an outer side, and a perimeter edge. The seal assembly includes a support ring and a sealing ring. The support ring is disposed at the perimeter edge and the first axial end. The support ring circumscribes the side plate. The sealing ring extends between and to a first axial sealing ring end and a second axial sealing ring end. The first axial sealing ring end is disposed at the support ring and the outer side.
