ABSTRACT:
A valve drive of an internal combustion engine, which has a reciprocating poppet valve and a spring element which impinges the closed reciprocating poppet valve with force against the action of a valve seat. The force characteristics are substantially independent of the lift characteristics of the reciprocating poppet valve. The spring element is part of a snap-in locking device, which is stationarily mounted in the engine and surrounds the valve stem of the reciprocating poppet valve. The snap-in locking device has snap-in elements arranged in the power flux between the spring element and reciprocating poppet valve. The snap-in elements are supported in the direction of closure of the reciprocating poppet valve on a snap-in surface of the valve stem when the reciprocating poppet valve is closed and on a snap-in surface of the snap-in locking device when the reciprocating poppet valve is open.
