Abstract: A self-adjusting hydraulic valve lifter for an overhead cam engine wherein this pressure fed hydraulic valve lifter is interposed directly between a valve and cam, the lifter including an upright, cup-shaped plunger engaging on the valve stem and being reciprocally received in a larger, inverted, cup-shaped follower which engages the cam and which is slidably guided in a fixed bore surrounding the valve stem, a pressure chamber being formed between an end of the plunger and the follower, with a helical compression spring positioned therein to normally bias the plunger and follower against the valve stem and the cam, respectively, and a fluid supply passage is provided to supply fluid under pressure to the pressure chamber, the fluid supply passage including a V-shaped groove with an O-ring seated therein to serve as a one-way check valve controlling the flow of fluid to the pressure chamber.
