1. A rocker arm assembly that cooperates with a cam having a low lift lobe and two high lift lobes, each of the low and high lift lobes including an actuating portion and a non-actuating portion, the cam rotating during operation of the internal combustion engine such that the actuating portions interact with the rocker arm assembly to rotate at least one of the inner and outer arms, the rocker arm assembly comprising:
an outer arm having a first outer side arm and a second outer side arm, each of the first and second outer side arms having a high lift lobe contacting surface, each of the high lift lobe contacting surfaces having an uppermost point that defines an outer arm tangent plane; an inner arm disposed between the first and second outer side arms and pivotably secured to the outer arm, the inner arm having a low lift lobe contacting surface and defining a latch bore, the low lift lobe contacting surface having an uppermost point that defines an inner arm tangent plane that is parallel to the outer arm tangent plane; and a latch assembly arranged at least partially within the latch bore of the inner arm, the latch assembly being movable between a first configuration and a second configuration, the latch assembly being configured to: (i) engage with the outer arm such that the outer arm rotates with the inner arm in the first configuration, and (ii) disengage the inner arm from the outer arm such that the outer arm rotates independently from the inner arm in the second configuration, wherein the inner arm tangent plane is spaced from the outer arm tangent plane by a minimum distance such that the non-actuating portions of the high lift lobes of the cam are offset from the high lift lobe contacting surfaces in a non-actuating condition and the actuating portion of the low lift lobe of the cam is offset from the low lift lobe contacting surface in an actuating condition. |
