Abstract
A vent assembly is provided for allowing internal contaminants to exit a solenoid. The vent assembly includes a vent membrane interposed between a gasket and a support. The support may have a variable diameter. The vent assembly attaches to the solenoid via a mating cover of the solenoid, which includes a vent opening that aligns with an opening in the gasket and includes a counter bore that captures the gasket. The vent assembly allows contaminants to exit the solenoid through a vent membrane. It also prevents contaminants from entering the solenoid around the vent membrane without the use of injection molding.
