摘要： A breakaway hose coupling includes axially separable housing sections (20; 22) maintained in coupled relationship with each other by a frangible coupling pin or set screw (74). Each housing section includes a valve controlled flow passage in which a spring biassed valve (30, 44; 60, 44') closes the flow passage when the housing sections are separated. Valve stems (42; 42') on the respective valves move into axial abutment with each other as the housing sections are coupled to mutually hold the respective valves open when the housing sections are coupled.

摘要： An auto-fill type float collar assembly is provided. The float collar assembly of the present invention has at least one curved flapper-style valve, preferably constructed of composite, non-metallic material. Each flapper of the present invention has a substantially 90° range of motion, and is closed via a torsion spring. Each flapper is held in the open (or “auto-fill”), position via an external shifting mechanism passing around, rather than through, the central flow bore of the assembly. A floatable actuation ball can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers when desired.

摘要： An auto-fill type float collar assembly (100) has at least one curved composite flapper-style valve assembly (40). Each valve assembly includes a flapper (140) that has a substantially 90 range of motion, and is closed via a torsion spring (44). Each flapper is held in the open (or "auto-fill"), position via an external shifting mechanism (150) passing around, rather than through, each valve body. A floatable actuation ball (110) can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers.

摘要： A breakaway assembly (100) for use in combination with a fuel dispenser apparatus is disposed between a segment of a hose (12) attached to a fuel dispenser unit (10) and a second segment of the hose (12) terminating in a nozzle (106). The breakaway assembly (100) has body portions with a first assembled condition and a second condition in which the body portions are separated. A fuel valve (128, 130) located in each of the body portions permits flow of fuel when the body parts are assembled and prevents flow upon separation. An element securing the body portions together releases engagement upon application of tension force to the hose (12), across the breakaway assembly (100), above a maximum level. In a preferred embodiment, the hose (12) is coaxial and a vapor valve (144) is also disposed within the breakaway assembly (100).

摘要： A frangible fluid fitting of the crash-worthy type utilizing a detent holding a self-closing valve in the open position. The detent engages a plurality of balls confined in a recess circumscribing the fitting attachment surface whereby only partial fracture of the fitting in any direction causes the self-sealing valve to close. One embodiment of the fitting permits both gravity and pressurized tank filling with automatic valve closing when the tank is full during pressurized filling.
