Quick connect coupling systems with insert

摘要

A threaded adapter is part of a quick-to-connect and quick-to-disconnect flexible hose coupling system. The adapter may provide a low-profile securement and seal between the port and the stem portion of the quick connect coupling. The adapter in combination with the fluid valve block orifice provides a seal that is further down in the valve block than the location of seals provided by other fluid couplings. Without relying on wrenching flats, the adapter also provides effective access to the hoses for repair and therefore is a cost saving device. The adapter may be a safe, reliable, easy to connect and disconnect component in a hydraulic system and is adaptable to accommodate any coupling including those in high and low pressure fluid and other systems.

主权项

1. A generally low-profile fluid coupling adapter system, comprising:
an insert threaded into a mating fluid port in an existing hose block, the insert comprising an inner port, a widened thread section widened relative to said inner port, and an annular clip groove; a clip configured to be disposed in said annular clip groove, about a quick connect stem, at least partially within a circumferential clip groove defined by said stem, said clip adapted to be received by said circumferential clip groove when said stem is coupled with said inner port, said quick connect stem adapted to be received by said insert and said fluid port; and wherein said stem comprises a main seal disposed about said stem and mating with a main seal mating surface that is defined by said fluid port, to provide a fluid tight seal between said port and said stem when said stem is coupled with said inner port; and a sleeve adapted to radially retain said clip compressed in said annular clip groove for removal of said stem from said inner port; wherein said sleeve is deployable between a first position, capturing the clip in the circumferential clip groove, and a second position, releasing the clip from the circumferential clip groove.
