Abstract:
A starting device for use on an internal combustion engine that includes an engine housing, a crankshaft mounted for rotation within the engine housing, and a flywheel mounted to the crankshaft for rotation therewith, the starting device comprising:a rotatable spring housing; an energy storing mechanism including at least one elastic member housed within said spring housing, said elastic member being loaded in response to said spring housing rotating in a loading direction, and said spring housing rotating in an unloading direction in response to unloading of said elastic member; a movable bracket; first, second, and third rotatable rollers, at least one of said rollers being supported by said movable bracket; an actuation assembly selectively moving said movable bracket between an engaged position and a disengaged position, rotation of the flywheel being converted through said rollers into rotation of said spring housing in said loading direction when said bracket is in said engaged position, and rotation of the flywheel not being converted into rotation of said spring housing when said bracket is in said disengaged position; and a coupling mechanism coupling said spring housing with at least one of the flywheel and the crankshaft in response to said spring housing rotating in said unloading direction, to cause startup of the engine.
