Abstract
A rocker arm includes a body having a first wall and a second with a central opening provided therebetween, the first wall having a first aperture extending therethrough and the second wall having a second aperture extending therethrough. An inner follower within the central opening selectively reciprocates along a reciprocation axis relative to the body, the inner follower extends through the first aperture and the second aperture. A lost motion spring biases the inner follower to move relative to the body along the reciprocation axis in a first direction. A lock member is moveable along a lock member axis between a coupled position which prevents the inner follower from moving past a predetermined position in a second direction which is opposite of the first direction and a decoupled position which permits the inner follower to move past the predetermined position in the second direction.
