ABSTRACT:
A valve lift control apparatus for an internal combustion engine, characterized by a hydraulic valve lifter constructed and arranged so that the motion of the cam for driving the intake or exhaust valve in each power cylinder is transmitted through the valve lifter to the valve without intervention of any axially abutting engagement between the movable members of the valve lifter by the fluid pressures intervening between the individual movable members. The valve lift control apparatus may further comprise a fluid pressure control device for varying the fluid pressure to be supplied to a hydraulic valve lifter in relation to certain operational conditions of the engine.
