Abstract
A rocker arm assembly for pivoting around a rocker shaft comprises a follower side arm, a valve side arm, and a latch assembly. The follower side arm comprises a main body (1016, 2016, 3016), a rocker shaft through-bore (1061), and a follower end (11, 21, 31) comprising a latch through-bore (1019, 2019, 3019). The valve side arm comprises a forked body (1026, 2026) and a valve end (12,22) extending from the forked body. A first arm extension (1025, 2025, 3025) and a second arm extension (1028, 2028, 3028) extend from the forked body and straddle the main body. A first distal end (1125, 2125) comprises a first latch pocket (51) distal from the forked body. A second distal end (1128, 2128) comprises a second latch pocket (81) distal from the forked body. The latch through-bore selectively aligns with the first latch pocket and the second latch pocket.
