Abstract
Apparatus for protecting reversible engines against damage during reversal of engine rotation notwithstanding that such reversal is initiated remotely by the operator by a single movement of the control handle without regard of the engine speed at the time such reversal is initiated, said apparatus including means for automatically cutting off engine throttle, determining the engine speed and direction of rotation at time reversal operation is initiated, and delaying, if necessary, restarting of the engine in the desired direction of rotation until rotation in the prior direction has been reduced to a safe speed for effecting such rotational reversal.
