Seal assembly for a rotary engine housing

An engine housing for an aircraft rotary engine, the engine housing comprising:

• a rotor housing including 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, and the rotor housing body forms a coolant passage;
• and
• a side housing assembly including a side housing body, a side plate, and a seal assembly,
• the side housing body is disposed at the first axial end, and the side housing body further forms the coolant passage,
• the side plate is disposed axially between the rotor housing body and the side housing body, and the side plate further forms the rotor cavity, and
• the seal assembly includes a support ring and a sealing ring, the support ring and the sealing ring extend about the axis, the support ring is disposed radially between the side plate and the side housing body, the support ring is further disposed between the rotor cavity and the coolant passage, the sealing ring is disposed axially between the support ring and the side housing body, and the sealing ring is further disposed axially between the side plate and the side housing body.
