DISPOSITIVO PER IL COLLEGAMENTO DI TUBAZIONI PER FLUIDI A RELATIVI OR-GANI EROGATORI.

摘要

The device is used typically in filling stations to connect the hose (3) of a self-service pump to the relative gun (2), and comprises a ball-and-socket fitting (10) composed of a first outer connecting member (4), and a tubular member (5) of which one end affords a spherical head (7) accommodated to a fluid-tight fit by the first connecting member (4) whilst the remaining end affords a sleeve (11) in which the tubular shank (13) of a second connecting member (6) is insertable, likewise to a fluid-tight fit; the sleeve (11) and the second connecting member (6) combine to create a pull-release safety coupling (18) equipped with an internal valve (16) which is designed to close and seal off the second connecting member (6) when this becomes separated from the sleeve (11).
