Abstract

A unitary rotor side-seal member arranged to be coupled to a flank of a rotor of a rotary engine, the side-seal member comprising: a frame, the frame having a rotor phasing gear aperture provided therethrough; a combustion gas seal portion; and a lubricant control seal portion, the combustion gas seal portion being provided about a radially outer portion of the frame and arranged to reduce a flow of combustion gas between the rotor and a sidewall of the engine in a radially inward direction, the lubricant control seal portion being provided at a radially inner location of the frame about the rotor phasing gear aperture, the lubricant control seal portion being arranged to reduce a flow of lubricant between the rotor and the sidewall of the engine in a radially outward direction.
