Abstract: In a hydraulic tappet including two cups slidable one within the other, of which the outer one cooperates with the surface of the cam of the camshaft through an adjustment disc while the inner one bears on the end of the valve stem, an expansion chamber is defined between the facing frontal walls of the two cups and is connected to the lubrication circuit of the engine through a supply duct controlled by an oleodynamic valve. The valve is constituted by a conical seat formed in a through-hole in the frontal wall of the inner cup to connect the expansion chamber to the lower part of the cup and intercept the supply duct, and a mushroom-shaped member whose head controls the conical seat and whose stem is inserted in the through-hole which acts as a guide for it.

Abstract: A hydraulic valve lifter for use in a direct acting overhead camshaft valve gear of an internal combustion engine includes a body member, a plunger member located at least partially within the body member, and a face member located at least partially within the body member and having a cam engageable surface thereon. A fluid reservoir is located between the face member and the body member and a pressure chamber is disposed between the plunger member and the body member for taking up lash in the valve gear. A leakage passageway is provided between the face member and the body member and provides for the flow of lubricating fluid from the reservoir to the cam engaging surface of the face member to thereby provide for lubrication of the cam engaging surface and the cam. The leakage passageway also provides for air leakage from the lifter to prevent air lockup of the lifter.
