Abstract: The invention relates to a breakaway coupling for a liquid line comprising a first and a second coupling part (3, 4) which each have a liquid connection and which can be separated by a defined force in the axial direction of the coupling and/or a tilting moment acting transversally to the axial direction. According to the invention, an antitwist device (12) is provided which prevents the first and second coupling part (4, 3) from twisting relative to one another during the operation of the coupling.

Abstract: The invention relates to a filling nozzle for dispensing liquid into a tank of a motor vehicle, having an actuating lever for a valve device and having a safety device moveable from a blocking position into an enabling position, wherein, in the blocking position, the valve device is closed regardless of the position of the actuating lever, and in the enabling position, the valve device can be opened by means of the actuating lever. The operative connection between the safety device and valve device is realized without external energy. The invention makes it possible to realize a misfilling inhibitor without external electrical energy, for example, and thus to fit a filling nozzle for urea solution, for example, in the explosion-protected region of a conventional fuel filling pump.

Abstract: A method for the pressing of a press fitting, with a tube inserted into the press fitting, by means of a pressing tool, wherein the press fitting has an encircling bead in which an 0-sealing ring is placed, wherein the tube ends within the press fitting and a first pressing is carried out within the bead, wherein, furthermore, a further pressing is carried out on the tube-insert side of the press fitting at a distance from the bead, the further pressing leading to press fitting and tube obtaining a conicity which prevents them being pulled off and runs in the same direction. Furthermore, the invention relates to a pressing tool suitable for carrying out the method.

Abstract: A fuel pump nozzle for delivering fuel, with a manually operated switch lever which is movable between a closed position, in which there is no delivery of fuel, and an open position, in which fuel is delivered, wherein the switch lever is biased by a restoring spring in the direction of the closed position and automatically returns to the closed position when the manual force applied declines, wherein the pump nozzle is provided with a hold-open aid which reduces the force required to hold the switch lever in a particular open position compared to the forces required to hold the switch lever open in other open positions.
