Abstract: A variable ratio rocker arm is provided for use in combination with the valve stem and push rod of an internal combustion engine. The rocker arm has an elongated slot defined between a rod seat and a toothed rack. A fulcrum rod is provided with a toothed sector and a curved sector, with the toothed sector being engaged with the toothed rack portion of the rocker arm. A roller bearing assembly is movably disposed between the rod curved sector and the rod seat, with the roller bearing assembly being rollable along the rod seat. An actuator arm is coupled to the fulcrum rod for simultaneously rotating and translating the fulcrum rod through the rocker arm slot. The operating arm causes the fulcrum rod to rotate and translate along the mating toothing from one point of pivotal engagement, corresponding to a first engine operating condition, to another point of pivotal engagement, corresponding to a second engine operating condition.

Abstract: A variable ratio rocker arm is provided for use in combination with the valve stem and push rod of an internal combustion engine. The rocker arm has a toothed rack. A fulcrum rod is provided with a toothed sector. A stationary support member has a rod seat. The fulcrum rod toothed sector engages the toothed rack of the rocker arm and the rod seat of the stationary support shaft. An operating arm is coupled to the fulcrum rod for simultaneously rotating and translating the fulcrum rod along the toothed rack of the rocker arm and the rod seat of the stationary support shaft. The operating arm causes the fulcrum rod to rotate and translate along the mating toothing from one point of pivotal engagement, corresponding to a first engine operating condition, to another point of pivotal engagement, corresponding to a second engine operating condition.
