Valve mechanism in an internal combustion engine with transmission means disposed to selectively open the engine exhaust valves (5) during the intake stroke to permit exhaust to be drawn into the cylinders during the intake stroke. The transmission means comprise a shaft (15) with a pair of pivot arms (17, 18) for transmitting a portion of the rocking movement of the intake rocker arm (2) to a rocking movement of the exhaust rocker aim (4). |
