Abstract

998,350. I.C. engine valve gear. JOHNSON PRODUCTS Inc. May 1, 1964 [May 16, 1963], No. 18206/64. Heading F1B. [Also in Division F2] In an I.C. engine having a hydraulic tappet in which a tubular push rod 20 seats on the bottom wall of a plunger 45 sliding in a tappet body 41, oil supplied to the push rod from rocker arm 11 passes through opening 48 and check valve 49 to compression chamber 46 and the push rod bore serves as an oil reservoir. Pressurized oil in rocker shaft 12 passes through orifice 15, passage 16 and opening 22 into the push rod bore 21. When the pressure in bore 21 exceeds that in chamber 46 e.g. when the valve 1 is closed, valve 49 opens to admit oil to chamber 46, thus taking up clearance. Air present in the oil is bled through opening 17 and between rocker shaft 12 and rocker arm 11 to passage 18, oil escaping from passage 18 lubricates the engaging surface. In a modification, the rocker arm passage 16 is offset from the opening 22 so that in the valve closed position air in push rod 20 bleeds through opening 22 and a groove in seating 19 whilst in the valve open position the rocker arm passage coincides with opening 22. An air bleed hole may be provided in the upper part of the push rod. In a further modification the push rod has a funnel-shaped end, oil being fed by gravity from a passage in the rocker arm which cyclically coincides with a passage in the rocker arm shaft to the funnel-shaped end.
