TODAY’S PATENT – LOW-SPILL COUPLING ASSEMBLY
The said invention (US12129952B1) was invented by David J. Vranish and patented by USPTO on July 8th, 2024. Currently, it stands assigned to the Colder Products Co.

The present invention relates to a fluid coupling system comprising a female and male coupling device designed for secure, sealed, and spring-actuated engagement. The female coupling device includes a main body with an opening leading to a fluid passageway, a sleeve encasing a stem with a stem head, and multiple seals for fluid containment. A spring biases the sleeve into a closed position, while a slidable clip allows the male device to lock into place. Upon insertion of the male coupling device into the female, the seals engage, and the sleeve and valve are displaced against their respective springs, enabling fluid flow between the two passageways.
The male coupling device features a second main body with its own fluid passageway, a valve member, and a spring for sealing. When connected, the female’s seals interact with the male’s outer body, and a major internal seal disengages as the valve opens. The clip mechanism on the female device ensures a secure and reversible connection, while the multi-seal design ensures leak-free operation during fluid transfer. This system offers a reliable, quick-connect solution for controlled fluid coupling in various industrial or mechanical applications.
