ABSTRACT:
A quick-connect filling device for transferring fluids to a valve having a female thread in its inlet port, the device comprising a stem having a through-going conduit for fluid flow therethrough and an enlarged upper plug end for sealing abutment with a tank valve, a plurality of externally-threaded screw segments, forming a single screw thread when aligned, and extending axially and positioned concentrically around the stem beneath the enlarged plug end, a sleeve-like element concentrically surrounding the stem and reciprocally slidable between a first locking position in which an upper portion of the sleeve-like element extends between the stem and the screw segments and outwardly urges the segments into threaded engagement with complementary female threads of the tank valve, and a second withdrawn open position in which the upper portion of the sleeve-like element extends only between the stem and a bottom portion of the screw segments, allowing the release of the segments from the engagement, a resilient element surrounding the screw segments in an area above the bottom portion, for urging the upper portions of the segments into contact with the stem and disengagement from the valve threads, and locking device for locking the sleeve-like element in the first locking position.
