Abstract

In an internal combustion engine, the engine casing has segmental flanges defining one or more annular guideways extending generally at right angles from the camshaft. At least one correspondingly annular segmental element is slidably disposed in each guideway such that one end thereof bears against the cam and the other end provides a seat for an associated valve push rod. Reciprocation of the element along the annular guideway actuates the push rod, and hence the valve. The segmental element may include an oil reservoir which receives oil from a duct or reservoir in the casing or flanges, and conducts the oil to an oil duct in the push rod.
