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.

Breakaway hose coupling

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.

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. Further, vapor conduits (114, 116 and 118) are provided to accommodate the flow of recaptured fuel vapor through the coupling. 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.

A breakaway hose coupling device (10') for releasably joining the hose ends of two fluid communicating hoses and for selectively disengaging and sealing such hose ends in response to a disengaging force of a preselected value is disclosed. The coupling device (10') comprises a coupling sleeve (12') defining an interior surface provided with an annular groove (80). The coupling device (10') further comprises first and second valve assemblies (20'and 22') each comprising a valve housing (24'and 25') having a forward end portion (26') for being received in the opposite ends of the coupling sleeve (12'), and a rearward end portion defining a threaded receptor (34') for engaging a hose end. Each valve housing is also provided with a passageway (30') therethrough communicating with the hose end, the passageway (30') defining a forwardly disposed valve seat (32'). Each of the valve assembly (20'and 22') further comprising a spring biased poppet valve (58') mounted within the passageway (30'). The valve housing (24',25') of one valve assembly (20',22') is provided with an annular recess (52') registering with the annular groove (80) as the valve housing is received in the sleeve (12'), the annular recess (52') being receptive of a coupling spring (82) which biases outwardly such that the outer radial portion (84) of the spring (82) is releasably received in the annular groove (80).

The coupling device (10) comprises a coupling sleeve (12) defining at least one shear pin hole (18) for receiving a shear pin (54) having a preselected shear strength. The coupling device (10) further comprises first and second valve assemblies (20 & 22) each comprising a valve housing (24, 25) having a forward end portion (26) for being received in the opposite ends of the coupling sleeve (12), and a rearward end portion defining a threaded receptor (34) for engaging a hose end. Each valve housing is also provided with a passageway (30) therethrough communicating with the hose end, the passageway (30) defining a forwardly disposed valve seat (32). Each of the valve assembly (20 & 22) further comprising a spring biased poppet valve (58) mounted within the passageway (30). The valve housing (24, 25) of one valve assembly (20, 22) is provided with an annular recess (52) registering with the shear pin hole (18) as the valve housing is received in the sleeve (12), whereby the shear pin (54) is received in the shear pin hole (18) and extends into a swivel ring member (52) rotatably mounted within the annular recess (52) thereby limiting the axial movement of said valve housing while allowing the valve housing to rotate within the coupling sleeve (12).
