Valve gear, for an IC motor, has a structured intermediate lever mounted under the camshaft to give a variable opening characteristic according to the motor loading and its speed

摘要

The valve gear, for an internal combustion motor, is operated indirectly from a cam through a swing or rocker lever. The mounting for the intermediate lever (4) for the rocker (3) is under the camshaft (2), near the mounting for the rocker lever (12) which operates the valve (1) as described in 10031783.9. The support body (6), fitted in the cylinder head, has a support curve (61) with its axis in the center zone over the rocker lever to support the intermediate lever.
