Title: Rocker arm and rocker arm assembly for engines

Abstract: A rocker arm assembly for an engine is disclosed. The rocker arm assembly comprises a rocker shaft having a first side and a second side and a rocker arm pivotably disposed on the rocker shaft. The rocker arm comprises a first portion disposed on the first side of the rocker shaft for receiving a force in a first direction from a brake actuator. The rocker arm further comprises a second portion disposed on the second side of the rocker shaft for engaging a valve in a second direction opposite the first direction. When the braking mode is desired, the brake actuator forces the first portion of the rocker arm in a first direction causing the rocker arm to transfer motion from the brake actuator to the exhaust valve or valves, thereby allowing exhaust to exit the combustion chamber.
