Abstract: Device for avoiding fluid delivery errors, comprising a primary coil (6), placed in a container (1) in the vicinity of a fluid delivery orifice (2) of the container, a control and measurement electric circuit (7) supplying power to the primary coil (6) to generate electromagnetic waves in the fluid delivery orifice (2), detector means (7, 8) sensitive to the waveform of the currents or voltages that appear in the primary coil (6) and that distinguish the presence and the type of fluid delivery nozzle (4) as a function of said waveform of the currents or voltages in the primary coil (6). Comparator means (11) determine if the measured oscillation frequency (fm) is different from a reference oscillation frequency (fr). If necessary, the user is warned, by alarm means (12), that he is about to fill his container (1) with the wrong type of fluid.

Abstract: The invention relates to a device comprising at least one safety shut-off control valve. A safety valve is optionally connected to said safety shut-off control valve, connected in series in the fluid flow path. In the safety shut-off control valve, a sealing valve is returned to a sealing position against a seat by means of a return spring, and is controlled by a linear actuator and a connecting rod for continuous adjustment of the valve opening. The connecting rod comprises two independent segments which are at least partially made from a ferromagnetic material and which are magnetically coupled to a magnetic coupling circuit that is activated by a coil. While electric power is being supplied to the coil, the magnetic field that said coil creates maintains the linking rod segments coupled to one another, such that the linear actuator can control the sealing valve.
