Latest Patents
One of MacMillan's latest patents is a fuel transfer valve. This valve system is designed to control the flow of fuel between two fuel tanks during a transfer operation. It prevents the return flow of fuel from a carburetor back to a previously filled tank. The system features a pair of valve bodies, each equipped with two mechanically operated sealing elements. One valve body has larger inlet and outlet ports to manage the fuel supply from the source tank to a vehicle carburetor. The other valve body has smaller ports to regulate excess fuel flow back to the selected source tank during engine operation. Each valve body includes a push rod connected to a single motor drive yoke element, with spring-biased sealing elements that have a seal carrier slidably supported on the push rod.
Another notable patent is a motor assembly that comprises a motor with a driven member extending from it. The assembly includes a housing that encases the motor and features an opening for the driven member. A resilient support member is positioned around the opening, providing support for the driven member as it extends through a passageway. This support member is molded around part of the housing, ensuring mechanical interlocking engagement.
