QUICK CONNECT COUPLING

摘要

Provided is a coupler including female and male couplers configured to be coupled together. The female coupler includes one or more detents and a release valve having a release valve member that is movable to an open position to allow for venting of fluid from a cavity in the female coupler to an area outside the coupler, and the male coupler includes a detent recess into which the one or more detents of the female coupler are urged radially inwardly into to couple the female and male couplers. By eliminating a threaded connection between the male and female couplers, the couplers prevent leakage of fluid and/or separation of the couplers due to vibration during use.

主权项

1. A female coupler including:
a body having axially inner and axially outer ends, an axially extending cavity for receiving a male coupler at the inner end, a plurality of circumferentially spaced openings extending through a wall of the body near the inner end, and a passage extending through the wall of the body near the outer end; a release sleeve surrounding the body at the circumferentially spaced openings and being movable between first and second positions relative to the body; a plurality of detents respectively received in the plurality of circumferentially spaced openings and being urged radially inwardly by the release sleeve when the release sleeve is in the first position and being movable radially outwardly when the release sleeve is in the second position; and a release valve having a release valve member movable relative to a valve seat in the body, the release valve member being movable between a closed position blocking communication between the axially extending cavity and the passage and an open position allowing for venting of fluid from the axially extending cavity to the passage.
