    摘要: An internal combustion engine includes an engine housing, a crankshaft supported within the engine housing for rotation with respect to the engine housing, and a flywheel fixedly mounted to the crankshaft and rotatable with the crankshaft in a starting direction to start the engine. A coil spring has an outer end fixedly interconnected with respect to the engine housing, and an inner end. A unidirectional clutch has a portion connected to the inner end of the spring. The unidirectional clutch is characterized by an interference condition in which the unidirectional clutch couples the inner end of the spring to the flywheel such that the flywheel and crankshaft may be rotated in the starting direction in response to unloading of the spring. The unidirectional clutch is also characterized by a non-interference condition in which the inner end of the spring is uncoupled from the flywheel. An input assembly is interconnected with the spring and selectively movable into contact with flywheel to load the spring in response to rotation of the flywheel. A locking mechanism selectively prevents the spring from unloading, and at least one manual actuator is actuable to disengage the locking mechanism from the spring to enable unloading of the spring.

    摘要: An internal combustion engine includes an engine housing and a crankshaft supported for rotation within the engine housing and rotatable in a starting direction to start said engine. At least one cup is fixedly mounted to the crankshaft for rotation therewith. A starter shaft is supported by the engine housing for rotation. A spring housing includes a circumferential flange that defines an annular track with the at least one cup, and a spring is housed within the spring housing. The spring has a first end interconnected with the spring housing and a second end interconnected with the engine housing. A friction roller is movable into the annular track and into engagement with both of the circumferential flange and the at least one cup to cause rotation of the spring housing and loading of the spring in response to rotation of the crankshaft. A unidirectional clutch is interconnected between the spring housing and the starter shaft, the unidirectional clutch causing rotation of the starter shaft in a starting direction in response to unloading of the spring, but not causing rotation of the starter shaft in a direction opposite the starting direction. At least one dog is interconnected with the starter shaft to engage the at least one cup in response to rotation of the starter shaft in the starting direction to thereby causes rotation of the crankshaft in the starting direction.

    摘要: An internal combustion engine includes a spring housing rotatably mounted to the engine's engine housing for rotation about an axis of rotation. An energy storing mechanism including at least one elastic member is housed within the spring housing. A spring loading mechanism includes at least one roller movable into and out of engagement between the engine's flywheel and the spring housing, such that rotation of the flywheel is converted through the at least one roller to cause rotation of the spring housing in a direction that loads the elastic member. An engine starting mechanism includes a helically threaded member interconnected with the spring housing and a starter pinion threaded onto the helically threaded member. Rotation of the spring housing in response to unloading of the elastic member causes the starter pinion to move into engagement with the flywheel, thereby rotating the flywheel and starting the engine.

    摘要: An engine starting and stopping device includes a first roller selectively abutting the flywheel of an engine for rotation on a first shaft in response to rotation of the flywheel. A second roller abuts the first roller and rotates in response to rotation of the first roller. A second shaft and an overwind clutch couple the second roller with a third roller such that the third roller rotates in response to rotation of the second roller. The third roller abuts a spring housing and causes rotation of the spring housing in response to rotation of the third roller. A spring is housed within the spring housing and is loaded in response to rotation of the spring housing. The overwind clutch slips when the spring is loaded to a preselected level to protect the spring from overwinding. The spring is selectively unloaded to rotate the spring housing in an unloading direction. Rotation of the spring housing in the unloading direction causes rotation of the engine's crankshaft and startup of the engine.

    摘要: An overhead valve engine including a cylinder bore having an outer end; and a crankshaft assembly including a substantially straight crankshaft, a substantially cylindrical journal eccentrically mounted on the crankshaft, a one-piece connecting rod rotatably mounted on the journal, and a counterweight mounted on the crankshaft. The engine also includes a cam shaft having at least one cam surface and an axis inward of the outer end of the cylinder bore; two valves having opened and closed positions; two valve stems, each valve stem being attached to a valve; and two generally L-shaped and pivotably mounted valve operating levers, each lever including a first lever arm having a cam follower in contact with the cam surface, a pivot axis about which the lever pivots, and a valve arm in contact with a valve stem, where movement of the lever caused by the cam surface causes the lever to pivot and the valve arm to depress the valve stem and thus open the valve.
