    Abstract: A hydraulic tappet has a body and a reciprocal plunger within the body. The plunger has an internal oil chamber in communication with the exterior of the tappet body. A floating metering element is positioned within the plunger chamber and has a surface which cooperates with a mating surface on the plunger cap to meter oil from the chamber to the outer surface of the plunger cap.

    Abstract: A hydraulic tappet is so constructed that the socket for the hollow pushrod is of two diameters, the lower portion being of smaller diameter and thereby providing a clearance space of increased radial width and bounding an intermediate reservoir space with the body wall between the larger oil entry reservoir and the radially narrower clearance space about the upper part of the socket of larger diameter. The clearance space about the upper part of the socket immediately above the lower part of reduced diameter leads to a collecting groove, the axial height of such clearance varying throughout the cycle. The central bore of the socket leading from the pushrod seat extends a considerable distance below the transverse bore leading from the collecting groove to provide an oil reservoir which supplies the hollow pushrod immediately upon start of the engine. The central bore stops short of the bottom of the socket, and the tappet is devoid of a disc valve at said socket bottom.

    Abstract: A system for varying the valve timing of an internal combustion engine to increase the retarding effect of the engine for braking purposes, to increase the compression ratio of a relatively low compression ratio engine to enhance starting, and to optimize breathing to improve the engine performance over the useful operating speed range. The valve timing is varied by changing the total valve train length so as to shift the points on the cam profile at which the valve opening and closing events are determined.

    Abstract: A hydraulic tappet in which the barrel is formed of powdered metal, sintered and compacted to a density permitting fluid from within the barrel to pass to the barrel exterior to provide lubrication therefor. The cam face of the tappet barrel may be a sintered component infiltrated with a hardening agent, or it may be formed by a cast iron disc suitably attached to the barrel. The cam face may also be a separate sintered metal disc, again suitably attached to the tappet barrel.
