| description | An improved direct acting hydraulic valve lifter (DAHVL) has features including reduced dead oil storage with lower mass and faster filling, improved air venting, internal oil recirculation and targeted oil supply that combine to reduce the presence of air in the lifter. Foam filling and baffle reconfiguration are included among means for reducing stored oil volume which can also improve the follower cylinder support. Means for venting along the piston and cylinder of the lifter are shown. The various features combine to limit air intake and to more quickly expel air which does enter the lifter. |
