Abstract
An internal combustion engine includes a combination intake and exhaust valve assembly. The combination intake and exhaust valve assembly includes an intake valve and an exhaust valve which are disposed in a coaxial relationship. The intake valve has an annular rim portion which is movable into and out of engagement with an intake valve seat. The exhaust valve has a head end portion with an annular rim which is movable into and out of engagement with a valve seat disposed on the intake valve. When the intake valve is operated from a closed position to an open position, the intake and exhaust valves move together. A pair of rocker arms may be used to move the intake valve from its closed position to its open position. A single rocker arm may be used to move the exhaust valve from its closed position to its open position.
