THE CRANK SHAFT TERMINATES IMMEDIATELY ADJACENT THE MAIN BEARING IN A SHORT SPINDLE OR THE LIKE FOR A PINION WHICH DRIVES BOTH THE OTHER SHAFTS. THESE SHAFTS ARE ARRANGED ON OPPOSITE SIDES OF THE CRANK SHAFT AXIS AND ARE PROVIDED AT THEIR ENDS WHICH PROJECT OUT OF THE HOUSING WIT MEANS FOR DRIVING ACCESSORY APPARATUS OR EQUIPMENT. THE IMBALANCE WEIGHT ON THE IMBALANCE SHAFT IS SO ARRANGED THAT THE MOVABLE ELEMENTS OF A CENTRIFUGAL REGULATOR OCCUPY THE FREE SPACE WITHIN THE PATH OF MOVEMENT OF THE WEIGHT. ONE END OF THE IMBALANCE SHAFT IS ARRANGED TO DRIVE A LUBRICATING-OIL PISTON PUMP.
