Vent Seal for Extreme Environment Applications

Abstract

Disclosed herein is a novel design of a vent seal for a sealed electronics component enclosure. The vent seal comprises a rubber element defining balloon portion which extends through an opening in the wall of the enclosure. The balloon portion expands into the interior of the enclosure when the air pressure outside of the enclosure rises and collapses when the pressure outside of the enclosure falls. The vent seal is also provided with an air router that allows the easy passage of air into the interior of the balloon portion, while inhibiting particulates from entering the interior of the balloon portion to prevent interference with the functioning of the vent seal.
