An environmentally-friendly test port mounting in a conventional gasoline/diesel fuel dispenser cabinet to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system. The technician may access the test port while the line system head pressure s maintained at a point above ground. The test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

A coupling for transferring fluids is provided, having a housing and a nipple which can be fastened thereto and separated from the housing when a predetermined axial pulling force is exceeded, while overcoming a spring force, and having a fluid duct traversing the housing and the nipple, a housing-side and a nipple-side non-return valve and is routed in a radially guided manner around a vented cylindrical interior of the nipple. A closure mechanism comprises respective valve-side pins and a sleeve arranged between these pins, the sleeve being axially movable in the interior of the nipple and lockable to at least one of the pins by means of spring pressure-mounted locking elements so that, with the nipple fixed, the non-return valves are held open against their spring force, and, with the nipple released, the housing-side non-return valve is completely closed and the nipple-side non-return valve is at least partially closed.

A permanent test port mounting in a conventional gasoline/diesel fuel dispenser to provide a technician access to the fuel line and perform various tests that enables testing to occur at a highline point in the line system to include all or at least more of the line system head pressure than has been possible before. In particular, the test port has a quick connect/disconnect fitting disposed in a collar intermediate a mounting for a filter in a conventional gasoline/diesel fuel dispenser and the filter to provide a technician access to the fuel line and perform various tests. The quick connect/disconnect fitting may also be coupled to a hose for draining fuel under pressure into a safety can to prevent spillage during replacement of the filter. The safety can may be emptied into the fuel tank to conserve the fuel, prevent polluting the environment and as a safety measure.

A fueling adapter configured to permit a fuel dispenser which terminates in a twist lock mating assembly to be used to supply fuel to a fuel tank which has a fuel receiver outfitted with a dry break connector connected thereto, said fueling adapter comprising a dry break assembly rotatably connected to a twist lock assembly via a rotational connector.

System, methods, and other embodiments described herein relate to controlling a fuel dispenser. In one embodiment, a method of controlling a fuel dispenser includes broadcasting a pairing signal to a vehicle, receiving, from the vehicle, a confirmation signal confirming completion of a pairing process between the fuel dispenser and the vehicle, transmitting, subsequent to the confirmation signal, a disable signal to the vehicle in response to data from one or more proximity sensors indicating that the vehicle is within a threshold range and a determination that the vehicle is refueling, and transmitting an enable signal to the vehicle in response to a determination that the vehicle is no longer refueling. The disable signal disables a moving capability of the vehicle, and the enable signal restores the moving capability of the vehicle.

The present invention relates to a pneumatically, high pressure gas powered emergency release coupling control and monitoring system (S) comprising a powered emergency released coupling (1) arranged in a fluid-supply line (32) for conveying hazardous fluids, said powered emergency released coupling (1) comprising a couple of coupling members (10, 11) provided with mating faces (10A, 11A) for sealing engagement of the coupling members (10, 11) and formation of a pressurizable chamber (12) between said coupling members (10, 11), said system (S) comprising an actuation line (7) connected at its one end to the pressurizable chamber (12) and at its other end to a source (C) of high pressure gaseous media (GH), preferably high pressure nitrogen gas, an first actuating device (4A, 4B) arranged in the actuation line (7), wherein said system (S) provides a gaseous media at a pilot pressure level to said pressurizable chamber (12) and to said actuation line (7) in a position downstream the first actuation device (4A, 4B) or via said pressurizable chamber (12) for detection of any leakage of gas in the control and monitoring system (S), said pilot pressure gaseous media preferably being 15 low pressure nitrogen gas. The invention further relates to a pneumatically, high pressure gas powered emergency release coupling (1) and a control and monitoring method for such a system (S).

A fuel dispenser includes a fuel nozzle configured to be connected to a vehicle fuel system, fuel piping configured to transfer fuel from at least one fuel storage tank associated with the fuel dispenser through the fuel nozzle into the vehicle fuel system, and a fraud detection valve apparatus. The fraud detection valve apparatus includes a cutoff valve configured to selectively prevent flow of fuel, a flow sensor configured to sense a flow of fuel, and processing circuity.
