Abstract

1414429 Cam mechanisms JOHNSON PRODUCTS Inc 1 Nov 1973 [6 Nov 1972] 50835/73 Heading F2K I.C. engine lubricating oil supplied via ports 32, 34 to the usual reservoir 68 of an hydraulic automatic back-lash adjuster pillar 16 is additionally metered from the reservoir by a flat valve disc 62 and co-operating valve seat face restrictor groove 72 to lubricate the valve gear. As shown, the hydraulic adjuster pillar 16 provides zero lash for an overhead camshaft I.C. engine valve operating mechanism of the type in which a rocker arm 8 has one end 14 pivotally mounted on a plunger 40 extending from the adjuster pillar 16, the other end engaging a valve stem 2, and a portion of its upper surface between its ends engaging a cam 10. In operation, lubricating oil entering the reservoir 68, and via the usual check valve plate 26 into the conventional bottom compression chamber, lifts the valve disc off its lower seat 60 to seat on the upper seat 64 and via face groove 62 meters an oil supply to the rocker arm pivot 14 and via a duct 56 directs a stream of oil to the cam 10. When the engine is not running, and there is no oil reservoir pressure, the valve plate 62 seats by its own weight on the lower face 60, in which position the plate 62 acts as a check valve to prevent ingesting of air into the reservoir 68 during the period of engine start-up before engine oil pressure has been established. More than one groove may be formed in the valve seat face 64.
