Abstract
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.
