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.

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.

A dispensing unit is provided having a circulation system for circulating a fluid in the dispensing unit is provided. The circulation system can include 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.

An apparatus for filling a chambered package can include a dispensing nozzle angled relative to a perpendicular of a machine direction of a carrying mechanism, the dispensing nozzle being disposed adjacent to the carrying mechanism having one or more chambered recess defined about a surface thereof, the dispensing nozzle being configured to dispense a quantity of the medium into the one or more chambered recess defined about the surface of the carrying mechanism. The apparatus includes a housing and at least one wiping material arranged to define an angle having a vertex toward the machine direction about a bottom surface of the housing, the angle of the at least one wiping material being configured to direct any of the quantity of the medium dispensed out of the second end of the dispensing nozzle, but not directed into the one or more chambered recess, into the one or more chambered recess.

A device for filling vehicles on assembly lines with a plurality of different operating media, which are fed from filling stations via connecting lines and special adapters into the circuits and tanks of the vehicles. The device structurally integrates the terminals of all tanks and circuits of a vehicle which are to be filled with an operating medium in a common assembly, configured as a filling unit installed in the vehicle. The filling unit can be brought into operative connection with a filling tool for all of the terminals of all filling stations of different operating media. The terminals for the same operating medium at the filling unit of the vehicle and the filling tool to be brought into operative connection are configured with congruent contours.
