ABSTRACT:
An engine cylinder head has valves reciprocally mounted thereto, each valve having a head which is seatable against a seat. The seat is recessed in a cylindrical bore defined by the head, the outer periphery of the head being in close proximity to the surface of the bore, with the head on the seat. The valve apparatus maintains a substantially closed valving state as the head is moved from the seat, until the head is removed from the bore.
