  • Valve mechanism for an internal combustion engine
    Patent number: 4559909
    Abstract: A valve mechanism for a poppet valve of an internal combustion engine having a conventional cam and rocker arm control mechanism. Valve springs are positioned and compressed between the poppet valve and a valve spring retainer. The valve spring retainer moves relative to the engine head responsive to engine speed to further compress the valve springs with increased engine speed. A hydraulic controller operates through linkage employing a detent mechanism such that step-wise advancement of the valve spring retainer results to approximate an ideal engine speed versus valve spring force curve.
