IGNITOR

摘要

An ignitor has a main body forming a support for insulators, a center electrode, an outer electrode and a spark controller electrically connected to the center electrode, a sleeve extending upward from the main body that incorporates the outer electrode, the center electrode extending through the sleeve to a position adjacent the outer electrode to provide a spark gap between the center electrode and outer electrode, and a barrier between the sleeve and main body to prevent condensation from entering the main body and contacting the insulators.

1. An ignitor, comprising:
a main body supporting a center electrode and insulators spacing the main body from the center electrode; a spark controller electrically connected to the center electrode; a sleeve having an upper end and a lower end, the sleeve being supported by the main body; the center electrode extending upwards from the main body through the sleeve and the sleeve having a part forming an outer electrode separated from the center electrode by a gap suitable for a spark to travel across the gap in response to energization of the center electrode, the sleeve providing a flow path for air to reach the gap; and the sleeve being separated from the main body.
