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.
Claims21
A solenoid assembly, comprising:
- a housing including an electrical conductor wound around a moveable core;
- a mating cover, coupled to the housing, including a vent opening and a counter bore;
- and
- a vent assembly for allowing internal contaminants to exit the housing, the vent assembly including:
- a gasket having an opening that aligns with the vent opening and that is captured in the counter bore of the mating cover;
- a vent support including a plurality of support sections;
- and
- a vent membrane interposed between the gasket and the support such that the internal contaminants can permeate from within the housing through the opening of the gasket to external ambient air, wherein the vent support sections are shaped such that the sections together form a rim for the vent membrane and provide ventilation for the vent membrane.
A vent assembly for use with an electro-mechanical solenoid, comprising:
- a gasket having an opening that aligns with a vent opening in a cover of the solenoid, wherein the gasket attaches to the solenoid via a counter bore in the cover;
- a vent support including a plurality of support sections;
- and
- a vent membrane interposed between the gasket and the vent support such that contaminants can permeate from within the solenoid through the opening of the gasket to external ambient air,
- wherein the vent support sections are shaped such that the sections together form a rim for the vent membrane and provide ventilation for the vent membrane.
A Vent assembly, comprising:
- venting means for allowing contaminants to permeate from within a solenoid to external ambient air;
- sealing means for securing the venting means to the solenoid and preventing external contaminants from entering the solenoid around the venting means;
- and
- supporting means for supporting the venting means and providing internal ventilation to the venting means when attached to the solenoid.
