Abstract A DEVICE FOR ADJUSTING THE BEGINNING OF FUEL INJECTION OF AN INJECTION PUMP IN WHICH THE DRIVING TORQUE IS TRANSMITTED FROM A COUPLING VIA AN AXIALLY MOVABLE SLEEVE TO A SECOND COUPLING, WITH THE TEETH OF ONE COUPLING HAVING A PITCH DIFFERENT FROM THE TEETH OF THE OTHER COUPLING AND AN ADJUSTING DEVICE COOPERATES WITH THE SLEEVE TO MOVE THE AXIALLY MOVABLE SLEEVE WHEREBY THE RELATIVE ANGULAR POSITION OF BOTH COUPLINGS IS ALTERED. AT LEAST THE DRIVING FLANKS OF THE TEETH OF ONE COUPLING ARE INCLINED RELATIVE TO THE RADICAL DIRECTION TO SUCH AN EXTENT THAT UPON TRANSMITTING THE DRIVING TORQUE BY THE COUPLINGS FRICTIONAL FORCES ARE DEVELOPED WHICH IN TOTAL ARE EQUAL TO OR GREATER THAN THE THRUST COMPONENT GENERATED IN VIEW OF THE BEVEL GEARING OF ONE OF THE COUPLINGS.
