Abstract
Systems for valve actuation in internal combustion engines with a dedicated rocker for actuating the at least one of two or more engine valves in a braking operation may include a biasing component, such as a compression spring, tension spring, spring catch, hydraulic actuator, pneumatic actuator for biasing the dedicated rocker in a biased direction away from the motion source, and a limiting component, such as a physical stop including a set screw or a stop integrated in the biasing component, for limiting the motion of the dedicated rocker in the biased direction. The biasing component and limiting component maintain the dedicated rocker in a controlled state and a positive, neutral position during operation.
