Abstract
A rocker arm may include a first arm defining a first longitudinal bore and a second arm defining a second longitudinal bore. The rocker arm may house a locking assembly including a first actuation pin extending through a first radial passage in the rocker arm, a second actuation pin extending through a second radial passage in the rocker arm, and a first lock pin located in the first longitudinal bore between the first and second actuation pins. An actuation assembly may be engaged with the first and second actuation pins and may be linearly displaceable between first and second actuation positions. The first and second arms may be rotatable relative to one another when the actuation assembly is in the first actuation position and may be fixed for rotation with one another when the actuation assembly is in the second actuation position.
