Abstract
A narrow accessway sewage pump remotely operable, multi-part, quick connect/disconnect slide coupling comprising a fixed portion that forms a first part of a slide-together, bayonet-type coupling with a movable portion forming a second part of the coupling. The movable part of the coupling supports a liquid pump and slides together with and is physically supported by the fixed portion. A third slide stop valve portion is positioned intermediate both the fixed and movable portions and all three portions of the coupling have interiorly formed open passageways for passage of liquid therethrough. The passageways in the three portions all come into alignment upon the three portions being properly seated together in assembled relation. The three portions have complementary sealing surfaces formed thereon which come together automatically to form a liquid pressure-tight seal around the aligned interior liquid passageways through the three portions upon all the portions being slid into and properly seated in assembled relation within the fixed portion. The intermediate slide valve portion further includes a discharge outlet slide stop valve structure which normally is out of alignment with the interior open passageways through the assembled fixed and movable portions of the slide coupling with the slide coupling in the open position but which is closed over the interior aligned passageways with the slide coupling in the closed position.
