A dispensing unit having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system comprises, a circulation circuit, and a mechanism configured to circulate the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

A stow bar for an aircraft fuel nozzle includes a U-shaped body formed of a base part, a first arm extending from one side of the base part, and a second arm extending from an opposite side of the base part. Each of the first arm and the second arm includes a free end located distally of the base part. Each free end includes a male connector for insertion through an aperture in a housing or a flange of the aircraft fuel nozzle. The stow bar is formed of a single, solitary piece of material. The single, solitary formation of the male connectors with the stow bar provide increased strength and durability to the stow bar connection with the fuel nozzle, and is an improvement over known support bar designs having female threaded connectors which receive screws that are prone to break and leave debris within the female connectors.

An additive injection system includes an additive injection controller operable to: (a) receive fuel data; (b) determine, from the fuel data, a total fuel amount corresponding to a total volume of fuel present in a fuel tank; (c) determine an untreated fuel amount corresponding to a delivered volume of untreated fuel delivered into the fuel tank, the untreated fuel amount determined based on the total fuel amount and a treated fuel amount corresponding to an expected volume of treated fuel expected to be present in the fuel tank; and (d) in response to determining that the untreated fuel amount exceeds an injection threshold, generate an injection signal to initiate injection of fuel additive into a fuel stream of untreated fuel being delivered into the fuel tank via the fuel tank inlet.

A bottle body comprises: a main body extending from a base to a shoulder; a neck extending from the shoulder to a mouth a thread along the neck; and one or more recesses along an exterior of the neck and extending along a longitudinal span of at least 30 mm.

A vapor control set screw valve applied into the handle of a fuel dispensing nozzle, including a valve bushing intermediately applied within the vapor return line within the handle, a set screw valve provided within the lateral channel formed of the bushing, an insert bushing applied to the dispenser handle, and the set screw, forming the valve, engaging within the insert bushing, and extending into the vapor return line bushing, to provide for its adjustment therein, to open or close the vapor return line within the nozzle in order to regulate and control the flow of the returning vapors being pumped back to the associated dispenser, and to the normally underground fuel storage tank associated with gasoline dispensing.

A fluid dispenser system is disclosed herein that is configured to switch between an open position in which fluid flows through a fluid channel and a closed position in which fluid is prevented from flowing through the fluid channel. The fluid dispenser system includes a valve disposed along the fluid channel and configured to move between the open valve position and the closed valve position, a trigger actuatable between an open trigger position and a closed trigger position which move the valve between the open valve position and the closed valve position, a trigger latch configured to move between a latched position in which the trigger latch fixes the trigger in the open trigger position and an unlatched position in which the trigger latch does not constrain movement of the trigger, and a solenoid with a solenoid pin. The solenoid is configured to translate the solenoid pin between an extended position capable of retaining the trigger latch in the latched position and a retracted position that allows the trigger latch to move into the unlatched position.

The disclosure provides a filling adapter for filling vehicles with various operating materials which are fed from filling systems via connecting lines and filling adapters into circuits and containers of the vehicles. The disclosure provides a mechanical clamping element for such a filling adapter that has a lower mechanical load on the filling port than the known clamping claws or balls. The clamping element has a partially circular contour with a cross-section which, starting from a lower and flat base surface, merges upwards into two side surfaces which are arranged at right angles to the base surface and run parallel to one another, wherein the two side surfaces each merge at their end section arranged opposite the base surface into an actuating surface that runs obliquely upwards and inwards.
