ABSTRACT:
A breakaway hose coupling with an integrated swivel mechanism for releasably joining two fluid dispensing devices, and for selectively disengaging such dispensing devices in response to a disengaging force in excess of a preselected value being exerted on said coupling device. The coupling (10) comprises a first valve assembly (12) for being secured on a first dispensing device and for selectively terminating the flow of fluid from such dispensing device when the coupling (10) is uncoupled. The coupling (10) further comprises a second valve assembly (14) with an integrated swivel mechanism (80) for being secured on a second dispensing device and for selectively terminating the flow of fuel from the second dispensing device when the coupling (10) is uncoupled. The coupling (10) also includes automatic disconnect means for maintaining the first and second valve assemblies (12 and 14) in an engaged position in the absence of disengaging force in excess of a preselected value being applied to the coupling, and for disengaging the first and second valve assemblies in response to disengaging force in excess of said preselected value being applied to the coupling, whereupon the first and second valve assemblies (12 and 14) terminate the flow of fluid from their operatively associated dispensing devices.
