摘要： PURPOSE:To obtain a governor device having a simple structure and high efficiency by bearing-supporting the stator of a flywheel magnet type generator in rotatable manners and controlling the throttle valve of an engine according to the revolution of the stator. CONSTITUTION:When a flywheel 2 revolves, an electromagnetic force nearly proportional to the engine revolution speed is generated between a magnet 4 and a core 5. If the engine revolution speed is equal to a set value, the electromagnetic force and the tension of a spring are balanced, and an arm 10 is held at a constant position. If the engine revolution speed increases over a set value, the turning moment acting onto the core 5 overwhelms the pulling force of the spring, and the arm 10 shifts to the direction for closing a throttle valve.

摘要： PURPOSE:To make it possible to control the spark advance with a high degree of accuracy in accordance with an engine speed by bearing a stator of a flywheel magnet type generator so as to allow the stator to rotate under electromagnet force produced between the stator and flywheel side magnets, and by associating an ignition unit with the rotation of the stator. CONSTITUTION:There is provided a multi-pole type (for example, eight pole type) rotor including a plurality of magnets 4 is attached to a flywheel 2 on a crankshaft 1. Further, there is provided a projecting pole type stator having cores 5 confronting the magnets 4 with a predetermined gap therebetween and each wound thereon with a plurality of windings 6. A flywheel magnet type generator is composed of the rotor and the stator. An arm 10 is attached to a holding member 7 for attaching the stator to a stationary side boss 9. Further, an arm 13 is supported to the boss 9 through the intermediary of a bearing 12, having its front end attached with a self-trigger type ignition unit 14, and the arms 13, 10 are associated with each other through the intermediary of a link mechanism 16.

摘要： PURPOSE:To provide a starter starting interlocking device of an engine which can prevent a starter restarting in the case of a flywheel reverse rotation owing to the repeating of ON and OFF of the cranking until an engine starts up. CONSTITUTION:In a starter starting preventive device in the starting of an engine, a restarting preventive means to prevent a restarting of a starter motor 5 in the case of a flywheel reverse rotation time owing to the repeating of ON and OFF of the cranking until the engine starts up, is provided by arranging a self-sustaining relay 2 and a relay 3 having an breaking contact 3a between an ignition switch 1 and a magnetic switch 4.

摘要： PURPOSE:To facilitate the ignition timing control with a simple mechanism by oscillating an oscillation member magnetically in response to the revolution of a disk which is turned synchronously with an engine and moving an ignition trigger coil. CONSTITUTION:When an engine is driven to turn a crankshaft, a disk 10 is immediately turned counterclockwise. An electro-magnetic force moving each of a plurality of magnets 13 and 14 toward the disk 10 is generated between both the vortex current generated at the disk 10 and the magnetic field of each of the magnets 13 and 14. An oscillation board 12 is oscillated clockwise through the center of a support pin 11 against the load of a spring 16. The oscillation of the oscillation board 12 causes another oscillation board 20 to be oscillated counterclockwise through the center of a support pin 21 via a link 24. As a result, a magnet and a pulser coil which are attached to the end of the oscillation board 20 and not illustrated in the drawing are moved in the direction of having the spark advance with respect to the turn of the disk 10.

摘要： PURPOSE:To spread the set degree of freedom in control and improve precision by constituting a governor from a disc consisting of a nonmagnetic body which revolves in synchronization with the revolution of an engine and a magnet which generates an electromagnetic force for swinging a swing member according to the revolution of the disc. CONSTITUTION:When a disc 3 consisting of a nonmagnetic body which revolves in synchronization with the revolution of an engine revolves, an electromagnetic force nearly proportional to the engine revolution speed is generated between an electric eddy current generated on the disc 3 by a magnet 6 and the magnetic field generated by the magnet 6. When the engine revolution speed is equal to a set value, the electromagnetic force acting onto a swing arm 5 and the pulling force of a spring 7 are made equal, and the swing arm stops at a constant position. When the engine revolution speed increases over a set revolution speed, the electromagnetic force acting onto the swing arm 5 increases, and the swing arm 5 is swung in the revolution direction of the disc 3, and a throttle valve is turned in the closing direction.
