Abstract: A rocker arm includes an outer arm with an outer follower and an inner arm which selectively pivots relative to the outer arm, the inner arm having an inner follower. A lost motion spring biases the inner arm to pivot relative to the outer arm. A lock pin which slides between a coupled position and a decoupled position. A pivot shaft includes a first portion a second portion centered about a first pivot shaft axis and a third portion located between the first portion and the second portion that is centered about a second pivot shaft axis which is parallel to, and laterally offset from, the first pivot shaft axis. The third portion supports the inner arm.

Abstract: A rocker arm includes an outer arm with an outer follower including a first outer roller and a second outer roller both supported on an outer arm roller shaft, the outer arm roller shaft having a first portion having a first diameter which is supported in the outer arm by a first outer bearing; a second portion having a second diameter which is supported in the outer arm by a second outer bearing; and a third portion having a third diameter such that the third diameter is smaller than the first diameter and the second diameter. An inner arm selectively pivots relative to the outer arm, the inner arm having an inner follower and also having an inner arm aperture through which the outer arm roller shaft extends such that the third portion of the outer arm roller shaft is located within the inner arm aperture.

CPC classification number: F01L1/181 , F01L1/047 , F01L1/2416 , F01L2001/186
Abstract: A rocker arm includes an outer arm; an inner arm which selectively pivots relative to the outer arm; and a latching arrangement which switches the rocker arm between a coupled state and a decoupled state. The latching arrangement includes a connecting bore which is terminated by a connecting bore floor; an oil supply bore which opens into the connecting bore through the connecting bore floor; a lock pin bore which opens into the connecting bore through the connecting bore floor; a lock pin within the lock pin bore where the lock pin prevents the inner arm from pivoting in the coupled state and where the lock pin permits the inner arm to pivot in the coupled state; and a retainer within the connecting bore which defines a chamber within the connecting bore which provides fluid communication between the oil supply bore and the lock pin bore.
