摘要： A breakaway hose coupling device (10) for releasably joining two fluid dispensing devices in fluid communications, and for selectively disengaging the dispensing devices in response to a disengaging force in excess of a preselected value being exerted on the coupling device. The coupling device (10) includes first and second valve assemblies (12, 14) for being secured on, and being placed in flow-though communication with dispensing devices and for selectively terminating the flow of fuel from such dispensing device. The first and second valve assemblies including first and second valve housings (16, 18) each having a valve mechanism mounted therein for selectively terminating the flow of fluid through the valve assembly. The device also includes a plurality of shear pins (48A-C) mounted in the second valve housing (18), and at least one stop member (50) carried by the first valve housing (16) for engaging only certain shear pins when the valve housings are engaged in selected relative rotational positions. Accordingly, when certain of the shear pins (48A-C ) are sheared by reason of force in excess of a preselected value being exerted on the coupling, the relative rotational positions of the first and second valve housing can be change to effect the securing of the coupling with certain of the remaining shear pins.

摘要： A breakaway hose coupling for releasably joining two fuel dispensing devices in fluid communication, and for selectively disengaging such dispensing devices in response to a disengaging force in excess of a preselected value being exerted on the coupling. The coupling (10) includes 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 includes a second valve assembly (14), including an elbow (72) and swivel connecting mechanism (70), for being secured on a second dispensing device and for selectively terminating the flow of fuel from such dispensing device when the coupling is uncoupled. Further, vapor conduits (28, 28A, 28B) are provided to accommodate the flow of recaptured fuel vapor through the coupling (10). The coupling (10) also includes automatic disconnect means (16) for maintaining the first and second valve assemblies (12, 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 (12, 14) in response to disengaging force in excess of such preselected value being applied to the coupling (10), whereupon the first and second valve assemblies (12, 14) terminate the flow of fluid from their operatively associated dispensing device.
