Abstract (en)
A low mass hydraulic or mechanical valve lifter (14) has an oblong configuration for reduced mass, with straight or narrowed sides (23) connecting longitudinally spaced ends having depending semi-cylindrical end walls (42) that are received in similarly shaped end portions of lifter gallery openings to absorb all longitudinal and lateral side loads. The lifter (14) is preferably made by investment casting of a steel alloy. The investment casting permits the use of thin semi-cylindrical walls at each end of the valve lifter (14) which also has internal reinforcing ribs (44) extending from its underside. <IMAGE>
