Title: Labyrinth for an ignition distributor cap and rotor assembly with atmospheric purging action

Abstract

This patent describes an ignition distributor to work with spark plug electrodes, a rotor electrode, a coil electrode and a shaft for an internal combustion engine with cylinders, the ignition distributor comprising: a bowl shaped housing; a distributor cap comprising: a generally dome shape with a generally hollow interior and with a circular shaped bottom to mate with the bowl shaped housing; spark towers equal in number to the number of cylinders of the internal combustion engine, projecting up from the top of the dome shape and slotted to accept spark plug electrodes and allow them to protrude into the distributor cap interior for communication with the rotor electrode; a vent tower projecting up from the top of the dome shape and provided with a vent port through to the distributor cap interior to allow for the outward flow of the atmosphere inside the distributor cap and bowl shaped housing; a coil tower projecting up from the top of the dome shape and slotted to accept a coil electrode and allow it to protrude into the distributor cap interior for communication with the rotor electrode; an inner labyrinth of annular shape on the interior surface of the dome shape surroundmore » the coil electrode and protruding into the hollow interior of the dome shape; and an outer labyrinth of annular shape on the interior surface of the dome shape surrounding the inner labyrinth thereby forming an annular channel.« less
