ABSTRACT:
An improved breakaway hose coupling (10) for releasably joining the hose ends of two fluid communicating hoses. The coupling (10) comprises first and second valve assemblies (12 and 14) for being secured on the hose ends and for selectively sealing the hose ends when the coupling (10) is disengaged. The first valve assembly (12) includes a first valve housing (18) having a forward end portion (22), and the second valve assembly (14) includes a second valve housing (20), also defining a forward end portion (22). The coupling (10) also comprises a latch housing (48) which circumscribes and extends outwardly from the forward end portion (22) of the second valve housing (20) so as to define a receptor for closely receiving the forward end portion (22) of the first valve housing (18). A ball latch mechanism is mounted within the latch housing (48) which secures the first valve housing (18) in the receptor in absence of disengaging force in excess of a preselected value. Also provided is a reset means for allowing the ball latch mechanism to be disengaged in absence of disengaging force in excess of such preselected value.
