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 provides a dispensing valve or fuel nozzle having an earth (ground) cable and/or a safety cap for covering the discharge opening, the safety cap connected by a cord to the dispensing valve, wherein the dispensing valve has an automatic retraction system for the earth cable and/or the cord of said safety cap.

Abstract: The invention relates to a filling nozzle for dispensing a liquid into a tank of a motor vehicle, having a main valve (5). It is provided according to the invention that a safety valve (7) is arranged downstream of the main valve (5), which safety valve can be moved from a closed position into an open position by means of an opening movement directed in an upstream direction, and that a safety device (11) is provided which has an operative connection to the safety valve (7) and which is designed to detect the insertion of the filling nozzle into a tank provided for the corresponding liquid and which effects a movement of the safety valve from the closed position into the open position when an insertion of the filling nozzle into a tank provided for the corresponding liquid is detected.

Abstract: The invention relates to a dispensing valve for dispensing liquids into a reservoir container, with a main valve and with an operating lever designed for opening the main valve against a force biasing the main valve into the closed position, wherein the valve actuation mechanism has a continuous characteristic with a smooth profile, with which, when subjecting the operating lever to an actuation force at the start of a valve opening stroke, a different opening force is exerted on the main valve than when subjecting the operating lever to the same actuation force during the later course of the valve opening stroke.

Abstract: A fuel hose nozzle for filling a tank having a filler the tank with liquefied petroleum gas has a tubular valve housing extending along an axis and having an outer end, a tubular valve guide axially shiftable in the valve housing between a front position and a rear position and forming an outlet port adjacent the outer end, and a valve in the housing movable between an open position permitting fluid flow into the valve guide toward the outlet end and a closed position preventing such flow. A valve piston in the valve guide and axially fixed in the valve housing is engaged in the front position of the valve guide with the port to block flow through same. A fitting sleeve surrounding and axially shiftable on the valve housing has at the outer end an end fitting complementary to the tank filler neck.

Abstract: The subject matter of the invention is a fuel pump nozzle, with an inlet (2), a discharge pipe (3), a main valve for controlling the stream of liquid between the inlet (2) and discharge pipe (3), a switching lever (4) for actuating the main valve, a first automatic safety shut-off which moves the main valve into the closed position if the liquid level in a tank to be filled reaches a filling level sensor arranged in the region of the discharge pipe (3), a second automatic safety shut-off which moves the main valve into the closed position if the liquid pressure at the inlet (2) drops below a minimum value, and a mechanism (13) for prestressing the main valve into the closed position, said mechanism bringing about a variable opening cross section of the main valve depending on the liquid pressure at the inlet (2).

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.
