Abstract
A switching rocker arm system includes a rocker assembly having a first end and a second end, and engaging a lash adjuster an and engine valve. The system further includes a first arm rotationally coupled to a second arm at the first or second end, and selectively rotationally coupled to the second arm at the other of the first end and the second end by a latch. In the latched position, a second cam engagement surface of the second arm engages the second cam to operate the engine valve in a high-lift mode, a biasing spring urges the second cam engagement surface into contact with the second cam, and a rotational stop prevents contact of the second cam engagement surface with a base circle portion of the second cam in the low-lift mode.
