Abstract
A distributor containing an apparatus for suppressing noise is described, comprising a first discharging gap and a second discharging gap which exists close to the first discharging gap both of which are located between the electrodes of a distributor rotor and a stationary terminal, wherein the second discharging gap is formed through a dielectric member which is fixed to the distributor rotor and/or a stationary terminal, the gap distance of the second discharging gap is shorter than that of the first discharging gap.
Claims7
A distributor for an internal combustion engine, containing an apparatus for suppressing noise, comprising:
- a distributor rotor which is located in the distributor and rotates at the same pace as a distributor driving shaft driven by the internal combustion engine,
- a plurality of segments of a dielectric member attached with a predetermined pitch along the surface of the outer periphery of said rotor,
- a segment of a metallic auxiliary electrode attached to the outer periphery surface of each of said dielectric member segments,
- a plurality of stationary terminals which are located in the distributor and arranged along a circular locus defined by the rotating distributor rotor,
- the portions of the surface of the outer periphery of said distributor rotor, between said spaced segments, and one side of each of said terminals defining a first discharging gap therebetween,
- the surfaces of the metallic auxiliary electrode elements and one side of each of the stationary terminals defining a second discharging gap therebetween as the rotor reaches the position of each terminal, and
- said second discharging gap is shorter than said first discharging gap.
A distributor for an internal combustion engine, containing an apparatus for suppressing noise, comprising:
- a distributor rotor which is located in the distributor and rotates at the same pace as the rotation of a distributor driving shaft driven by the internal combustion engine;
- a plurality of stationary terminals which are located in the distributor and are arranged along a circular locus defined by the rotating distributor rotor with a first discharging gap maintained between the terminals and the distributor rotor;
- a dielectric member and means defining a second discharging gap, and both the dielectric member and the second discharging gap are between the terminals and the distributor rotor;
- wherein one side surface of said dielectric member, which surface is connected to said second discharging gap, is in said first discharging gap so that the gap distance of said second discharging gap is shorter than that of said first discharging gap and,
- a metallic auxiliary electrode attached to said one side surface of said dielectric member.
