Abstract
A dynamic seal for containing gas flow between a roller valve and a cylinder in an internal combustion engine. Vents from the cylinder cavity allow pressure therefrom, particularly on the compression and power strokes, to exert a force against the back of a seal recessed into the outside of the engine block around a cylinder gas port. The force compresses the seal tighter against the roller valve.
