Title:
REVOLUTION-VARIATION ABSORBING APPARATUS FOR ENGINE
Document Type and Number:
Japanese Patent JPS616446
Kind Code:
A
Abstract:
PURPOSE:To improve the revolution-variation absorbing action by offsetting the magnetic-force action immediately after the time when the magnetic-force action becomes max and preventing the reverse action of the magnetic force, in an apparatus for absorbing the revolution variation of an engine by the magnetic force. CONSTITUTION:Permanent magnets 4a and 4b are arranged with the S poles outside on a diameter line of a flywheel 3. Further, permanent magnets 4c and 4d are arranged with the N poles outside on another diameter line. A pair of permanent magnets 6a dna 6b having electromagnetic coils opposed to the permanent magnets 4a-4d are arranged. Position marks 9a and 9b are marked,and a sensor 10 for detecting the position marks is installed. The sensor 10 detects the time when the permanent magnets 4a-4d are opposed to the magnets 6a and 6b. Electromagnetic coils 7a and 7b are operated by the detection signal, and each magnetic force of the magnets 6a and 6b is offset by the action of the electromagnetic coils 7a and 7b.
