Distributor with noise suppressing device

Claim 2

A distributor with noise suppressing device having a pair of electrodes which comprises a rotor electrode fixed on a rotor and a side electrode built in a cap of the distributor, wherein said pair of electrodes have a thin metal member which extends from one electrode to the other and in the rotational direction of said rotor electrode for suppressing the generation of radio noise.

Claim 3

A distributor as claimed in claim 1, wherein said thin metal member is made of a separate member fixed to said rotor electrode.

Claim 4

A distributor with noise suppressing device comprising: a rotor; a rotor electrode fixed on said rotor for rotation therewith; a distributor cap covering said rotor and rotor electrode; a plurality of side electrodes fixed at separate locations to said cap about the interior of said cap adjacent the path of rotation of said rotor electrode, said rotor electrode including a conductive plate member having an outer edge extending into proximity with each of said side electrodes in turn as said rotor electrode is rotated; a thin metal plate member having a thickness substantially less than the thickness of said outer edge of said conductive plate member and fixed to one of said electrodes so that the initial spark between said rotor electrode and each of said side electrodes in turn occurs through said thin plate member, and the main spark occurs between said conductive plate member and each of said side electrodes in turn to suppress radio noise generated by said sparks.

Claim 5

A distributor with noise suppressing device comprising: a rotor; a rotor electrode fixed on said rotor for rotation therewith; a distributor cap covering said rotor and rotor electrode; a plurality of side electrodes fixed at separate locations to said cap about the interior of said cap adjacent the path of rotation of said rotor electrode, said rotor electrode including a conductive plate member having an outer edge extending into proximity with each of said side electrodes in turn as said rotor electrode is rotated; a thin metal plate member having a thickness substantially less than the thickness of said outer edge of said conductive plate member and fixed to one of said electrodes so that the initial spark between said rotor electrode and each of said side electrodes in turn occurs through said thin plate member, and the main spark occurs between said conductive plate member and each of said side electrodes in turn to suppress radio noise generated by said sparks.

Claim 6

A distributor as in claim 3, wherein said thin plate member extends parallel to said conductive plate member.

Claim 7

A distributor as claimed in claim 4, wherein said thin metal member is formed by cutting off the upper and outer edge of said conductive plate member of said rotor electrode.

Claim 8

A distributor with noise suppressing device as claimed in claim 4, wherein the thickness of said metal member is between 0.04 mm and 1.50 mm.

Claim 9

A distributor as in claim 4, wherein said thin plate member is fixed to said conductive plate member.

Claim 10

A distributor as in claim 4, wherein said thin plate member is fixed to each of said side electrodes.

Claim 11

A distributor as in claim 8 wherein each of said thin metal members is fixed at the respective lower end of said side electrode, thereby suppressing the generation of radio noise.

Claim 12

A distributor as claimed in claim 9, wherein said thin metal member is made of a separate member fixed to said rotor electrode.
