A liquid dispensing nozzle for dispensing a liquid into a receptacle, and for recovering vapor from the receptacle during dispensing. The liquid dispensing nozzle (10) includes a body (12) defining a liquid passageway (14) therethrough and a vapor passageway (16) therethrough. The nozzle also has a spout assembly (17) including a liquid tube (134) for being placed in fluid communication with the liquid passageway (14) of the body (12). The spout assembly also including a spout tube (136). The liquid tube (134) is disposed within the spout tube (136) such that a further vapor passageway (16.sup.1) is defined within the spout tube (136). The spout assembly (17) also includes a support ring (138) for releasably securing the spout tube (136) to the body (12), with the support ring (138) defining a passageway therethrough which establishes fluid communication between the further vapor passageway (16.sup.1) and the vapor passageway (16) of the body (12). A first tube support member (150) is provided for holding the liquid tube (134) in position within the spout tube (136) and to facilitate the communication of liquid to the liquid tube (134), the first tube support member (150) defining a liquid passageway (154) communicating with the liquid tube (134). Further, a check valve housing (168) is provided for establishing fluid communication between the liquid passageway (14) of the body (12) and a liquid passageway (154) of the first tube support member (150).

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 liquid dispensing nozzle (10) with a pump pressure responsive automatic shut-off mechanism. The nozzle (10) comprises a body (12) with an internal passageway (13) therethrough defining an inlet port (14) for being connected to a dispensing pump and an outlet port (16). A main valve (18) is mounted in the body (12) for selectively opening and closing the passageway (13) to the flow of liquid, and a latch mechanism (29) is provided for selectively closing, and prohibiting the opening of, the main valve (18). The nozzle (10) further comprises automatic shut-off mechanism for releasing the latch mechanism so as to close, and prohibit the opening of, the main valve when supply pressure from the dispensing pump falls below a preselected value. Such automatic shut-off mechanism includes an actuator member ( b 43) operatively associated with the latch mechanism (29) and movably responsive to fluid pressure within the passageway between the inlet port (14) and the outlet port (16) reaching a preselected value.

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.
