Rotary engine rotor housing having coolant cooled bridged exhaust port

摘要

A rotary engine rotor housing having an exhaust port in the rotor housing's inner peripheral wall which is spanned at the center by a peripherally extending bridge that is coextensive with the inner peripheral wall and has a coolant passage therethrough through which coolant is forced to circulate from one axial flow coolant passage in the rotor housing to another by means of heating, velocity differential, ram effect and a negative pressure zone.
