Abstract

1292762 Lubricating IC engine valve gear JOHNSON PRODUCTS Inc 18 Jan 1971 [20 April 1970] 2372/71 Heading F1B In a mechanical tappet 10 the flow path for oil from the tappet reservoir 22 to an opening 27 in the push-rod seat 16 in the tappet body 24 includes a slot 40 in the face 42 of the seat engageable by a face 26 in the body. The seat 16 may be biased against the face 26 or kept in contact therewith by the seat being an interference fit in the body over part of its length, Fig. 5 (not shown), the slot 40 then forming a metering cross-section in the flow path. The seat (16b), Figs. 6 to 8 (not shown), may be a clearance fit in the tappet body, the annular gap therebetween forming the metering crosssection.
