A recently granted patent (Publication Number: US11885285B2) discloses a fuel vapor switching and venting valve for internal combustion engines. The valve comprises an electromagnet with an armature, a first connection, a second connection, a spring, a flow limiting element, a first valve seat, and a valve body. The valve body has two contact surfaces for interacting with the first and second valve seats, with the second valve seat being axially displaceable and loaded by the spring in the direction of the valve body.

Furthermore, the valve includes features such as a flow housing part with a nozzle, a control body within the nozzle, and a spherical or conical flow around surface on the flow limiting element. The design also incorporates a radially outer ring, passage openings, and a stop to minimize gaps between components. Additionally, the valve body is gimballed to a valve rod and includes a carrier element made of solid material and a sealing element made of elastic material. The electromagnet features a core and a sliding bush for guiding the armature and sealing the connections. Overall, the components are arranged axially and are displaceable along a common axis, providing efficient fuel vapor switching and venting capabilities for internal combustion engines.
