  • Latching valve assembly having position sensing
    Patent number: 10253900
    Abstract: A latching valve assembly which controls the flow of air and purge vapor between a fuel module and a carbon canister, where a change in an electrical property of the latching valve assembly is used to detect whether the latching valve is in the open position or the closed position. The latching valve assembly of the present invention eliminates the need for a physical switch solution, mechanical or non contact solutions, eliminates complexity of valve hardware requirements, and only adds minor electric components and software to identify the latch position. This system eliminates valve complexity and mechanical connections required for electrical conductivity.
