Abstract
Abstract A contactless distributor in which the ignition timing is energized in response to signals produced by a plurality of magnetic elements moving in a circular path past a magnetodiode pickup element. The magnetic elements are mounted on a plate or disc attached to the distributor shaft and the pickup element is mounted for movement along the path to vary the ignition timing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
129 words
In An ignition distributor for internal combustion engines, in combination: a distributor body; a distributor shaft rotatably journaled therein; a structure of magnetic mass connected to said shaft for rotation therewith along a circular path with said body; a pickup member carried by said body and positioned adjacent said path to receive signals from said magnetic structure as it sweeps therepast, said pickup member being a magnetodiode; an arm pivotally mounted at one end within said body and carrying said pickup member at its opposite end; spring means normally urging said arm to a predetermined position within said body; an engine manifold vacuum-controlled linkage for opposing the action of said spring means; and a mounting plate fixed within said body, said arm being pivotally connected to said mounting plate.
Claim 2
Dependent Claim
