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.
