Abstract
A rocker arm includes an outer arm defining a bore; an inner arm which pivots relative to the outer arm, the inner arm defining a stop surface; a lost motion spring which biases the inner arm to pivot relative to the outer arm in a first direction; and a lock pin that slides within the bore between a coupled position in which the lock pin prevents the inner arm from pivoting relative to the outer arm past a predetermined position in a second direction which is opposite of the first direction and a decoupled position in which the lock pin permits the inner arm to pivot relative to the outer arm past the predetermined position in the second direction; such that the lock pin and the stop surface act together to limit the extent to which the inner arm pivots relative to the outer arm in the first direction.
