Title: Ignition distributor for internal combustion engine
Inventor: GOTO HIROYUKI
IPC: F02P7/067
Filed: 1986-11-20
Abstract: PURPOSE:To prevent the malfunction of an ignition distributor due to vibration by providing the magnetic circuit of a pickup with two magnetic gaps formed by the teeth of a signal rotor and brackets. CONSTITUTION:When the tip of a supporting bracket 6 of a pickup 3 is opposite to one tooth 2 of a signal rotor 1 through a magnetic gap A, and moreover the tip of an extension 7 of a fixed bracket 5 and another tooth of the signal rotor 1 form a magnetic gap B in a direction opposite to the gap A, the magnetic flux of a magnet 4 passes through the magnetic gaps A, B. The bracket 6 and the extension 7 become repeatedly opposite and unopposite to the tooth 2 per rotation of the signal rotor 1, and thereby the quantity of the magnetic flux passing through the above-mentioned courses varies to cause the pickup 3 to generate output voltage according to the above-mentioned quantity of the magnetic flux. Since when vibration makes the magnetic gap A smaller, the magnetic gap B becomes larger in proportion to the reduction in the gap A, the quantity of the magnetic flux passing through the gaps A, B is not affected, and no noise occures in the output voltage of the pickup 3. Thus the vibration can not cause the malfunction of an ignition distributor.
