    Abstract: A metered mechanical tappet utilizing a push rod seat permanently retained by a separate retainer or by a press-fit within the cavity of the tappet upon an annular shoulder of t he latter. Oil flow is obtained by a slot in the surface of the seat supported by said shoulder, the slot at least extending radially from the oil reservoir directly below the seat to the outer wall of the seat, from whence it passes to the interior of the seat and to the push rod by means of an annular path between the outer seat wall and the cavity along at least a portion of the axial extension of the seat. The actual metering is accomplished by either the slot, in which case the annular path has a substantial radial thickness; or by the annular path, in which case its thickness is considerably less than any of the dimensions of the slot.

    Abstract: A hydraulic lifter with bleed provisions opening near the end of every lift (valve opening) stroke to pump down the lifter''s high pressure oil chamber. A lifter body, centrally bored, houses a plunger which is movable to expand and contract the high pressure chamber. Plunger movement adjusts the lifter length. The lifter rides in a close fitting sleeve. An oil feed opening through the sleeve supplies oil, once per cycle, to a reservoir through aligned openings in the lifter body and plunger. Near the end of each lift stroke, when the compression on the lifter is great, a bleed hole through the lifter body aligns with a bleed passage in the sleeve. Oil is repeatedly forced from the high pressure chamber, assuring the removal of all air accumulated in the chamber and stopping initial valve lash and clatter.

    Abstract translation: 一个液压升降器，带有排气装置，靠近每个升程（阀门开启）行程的末端，以抽出升降机的高压油室。 中心钻孔的升降机体容纳可移动以使高压室膨胀和收缩的柱塞。 柱塞运动调节升降器长度。 升降机骑在紧密的套筒里。 通过套筒的供油开口通过升降机主体和柱塞中的对齐开口向每个循环提供一次油。 靠近每个升降行程的末端，当升降机上的压缩很大时，穿过升降机体的排放孔与套筒中的排放通道对准。 油从高压室反复强制，确保清除积聚在室内的所有空气，并停止初始的阀门间隙和咔嗒声。

    Abstract: A hydraulic tappet is formed by a barrel having a closed end and a plunger reciprocal within the barrel. The plunger has an oil chamber and a cap is seated on one end of the plunger to close the oil chamber. Passage means are provided at the seat of the cap upon the plunger for the relief of air within the plunger chamber.
