Abstract: A rocker arm assembly includes an outer arm having first and second low lift lobe contacting surfaces, an inner arm, and a latch assembly. The inner arm includes first and second opposed sidewalls extending between a first end and a second end, and a high lift lobe contacting surface disposed between the first and second opposed sidewalls. The first end is pivotably secured to the outer arm and operably associated with an engine valve, and the second end is operably associated with a lash adjuster and defining a latch bore. The latch assembly is movable between a first configuration and a second configuration. In the first configuration, the latch assembly engages the outer arm such that the outer arm rotates with the inner arm, and in the second configuration, the latch assembly disengages the outer arm such that the outer arm rotates independently from the inner arm.

Abstract: A modified rocker assembly having an offset end is designed for engine heads having an obstruction preventing use of a symmetric switching rocker arm. The modified rocker assembly has an obstructed side and a non-obstructed side and has an outer structure with a first end, and an inner rocker structure fitting within the outer structure, the inner structure also having a first end. The modified rocker assembly has an axle pivotally connecting the first ends of inner structure to the outer structure, such that the inner structure pivots within the outer structure around the axle. At least one torsion spring on one side of the axle rotationally biases the inner structure relative to the outer structure. The outer structure is offset on the obstructed side as it extends from the second end toward the first end, creating the first offset portion to provide additional clearance on the obstructed side.
