Abstract
A valve deactivator mechanism includes a flanged valve actuator that is operatively connected to a conventional spring biased poppet valve, either intake or exhaust, and which is slidably received in a flanged cam follower adapted to be reciprocated by an engine driven camshaft, a spring being operatively positioned to normally bias the flanges of the cam follower into engagement with each other and, a solenoid coil is operatively positioned such that when it is energized the flange of the valve actuator acting as an armature is electromagnetically coupled to the flange of the cam follower that operates as a solenoid pole piece whereby the cam follower actuates the valve actuator to control the opening and closing movement of the poppet valve and, when the solenoid coil is deenergized the valve actuator is uncoupled from the cam follower whereby the poppet valve is deactivated.
