Abstract (en)
[origin: US2022056907A1] Disclosed are improved locking mechanisms for vessels, including both pressure and vacuum/suction vessels, used in swimming pool and spa equipment. These improved locking mechanisms provide a more robust, reliable seal between the lid and the body of the vessel, and include features that make moving the vessel between its sealed and unsealed positions easier. More specifically, the locking mechanisms include features that allow the lid to move into its sealed position when the locking ring is rotated relative to the vessel in a first direction, and that allow the lid to release from its sealed position and lift off the body when the locking ring is rotated relative to the vessel in a second direction opposite the first direction.
