Appl. No.:

10/369255

Inventors:

Neal L. Keefer - Portland OR, US
Kenneth A. Watson - Vancouver WA, US

International Classification:

F16K 17/38

US Classification:

137 72, 137 39, 137 73, 137 80, 137202

Abstract:

An improved thermal relief vent for a fuel tank, and a method of manufacturing the same, includes a thermal relief ring that is used to create a mechanical seal within the vent. The thermal relief ring, at room temperature, is crimped in place by use of the vent cap itself. The crimped thermal relief ring creates a mechanical seal between the vent and the vent cap, up until a predetermined thermal relief point, at which time the thermal relief ring will soften and/or yield and release the vent cap from the vent body.
