Abstract
A rocker arm includes an outer arm and an inner arm which selectively pivot relative to each other. A lock pin moves between a coupled position in which the lock pin prevents the inner arm from pivoting relative to the outer arm past a predetermined in a first direction and a decoupled position in which the lock pin permits rotation past the predetermined position in the first direction. A lost motion spring biases the inner arm to pivot relative to the outer arm in a second direction which is opposite of the first direction. A travel stop extends along a travel stop axis and has a travel stop surface such that the extent to which the inner arm pivots relative to the outer arm in the second direction is dependent upon the rotational position of the travel stop about the travel stop axis.
