摘要： The input shaft of an oil pump extends from the pump casing in parallel to the power takeoff shaft of a two-cycle engine. The shaft has conical discs of a variable speed drive attached thereto. An endless-belt drive belt is stretched within the outline of the conical disc from a pulley on the drive shaft to the pump pulley, so that the pulleys are placed inside the disc for protection and to form a compact structure.
