Anti-clatter engine brake and engine having same

An engine comprising:

• an engine block having cylinders;
• a cam shaft arranged on the engine block and having cam lobes;
• a rocker shaft carrying rocker arms configured to engage the cam lobes of the cam shaft;
• and
• an engine brake mounted to the engine block and including:
• an eccentric mounted to the rocker shaft and coupling one of the rocker arms to the rocker shaft to pivot eccentrically as the eccentric pivots about the rocker shaft, the eccentric being in a braked condition or an unbraked condition;
• an actuator capable of pivoting the eccentric about the rocker shaft to move the eccentric from the unbraked condition to the braked condition;
• and
• an anti-clatter assembly movable from an active state associated with the unbraked condition of the eccentric to an inactive state associated with the braked condition of the eccentric, the anti-clatter assembly providing to the eccentric a restraining force in the active state and no force or a yielding force in the inactive state, the restraining force being greater than the yielding force, the restraining force being sufficient to impede the eccentric from pivoting about the rocker shaft in the unbraked condition and the yielding force being insufficient to impede pivoting of the eccentric in the braked condition.
