Abstract: The invention relates to a coupling element (2), which comprises a first liquid connection (3) for connecting to a first part of a liquid line (1) and a second liquid connection (4) for connecting to a second part of a liquid line (5). In addition, the coupling element comprises a break-away coupling (6). The first liquid connection (3) is designed to establish a threaded connection to the first part of the liquid line (1). The two longitudinal axes (7, 8) of the liquid connections (3, 4) lie at an angle to each other. According to the invention, a rotation-preventing element (9) is provided on the first liquid connection (3) of the coupling element (2), which rotation-preventing element permits a relative rotation between the first part of the liquid line (1) and the coupling element (2) if a defined torque acts between the first part of the liquid line (1) and the coupling element (2). Safe operation of the coupling element is ensured by the rotation-preventing element according to the invention.

Abstract: The invention relates to an annularly closable band for encircling one or more articles, having an inner side, which is intended to face the article or articles to be encircled, an outer side located opposite the inner side, and two end regions (4, 5), which are made to overlap one another in order to close the band, wherein the end regions have corresponding closing elements, which are designed to be brought into engagement with one another such that the band has a substantially smooth outer circumferential surface in the closed state. The invention also relates to the use of a corresponding band as a protective cover for a component of a dispensing device, preferably as a protective cover for a breakaway coupling of a dispensing nozzle.

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.
