摘要：
A pair of adjacent valves (intake or exhaust) are operated by a single cam lobe on an engine camshaft via a bucket tappet, the arrangement being such that both the bucket tappet and the valves are rotatable during engine operation to reduce wear thereof. Preferably, a hydraulic lash adjuster is operatively associated with the bucket tappet and with a thrust member engaging the free stem ends of the valves.
