The device for generating an electrical current, intended for a pipeline, includes a pipe element (), a rotor () suitable for being set in motion by the fluid and a stator () arranged to cooperate with an end of the rotor () opposite to an axis of rotation () of said rotor () in order to generate the electrical current. The axis of rotation () is mounted at its opposing longitudinal ends () on first and second supports () arranged on either side of the plane of rotation (P) of the rotor () and each linked to the pipe element (). The stator has at least one ring () arranged on one side of the rotor (), and each ring () includes a circuit suitable for generating all or part of the electrical current when excited by a magnetic element of the rotor ().

Current generation device for pipeline

An electromagnetic machine () has two first elements, each one having: at least one first electrically conductive track () in the form of a crenellated annular line able to form a first plurality of electromagnetic circuits () able to interact with at least one magnetic element of the electromagnetic machine; at least one second electrically conductive track () arranged in the form of a crenellated annular line able to form a second plurality of electromagnetic circuits () able to interact with at least one magnetic element of the electromagnetic machine, said second track () being formed along said corresponding first track () and such that the circuits () of the second plurality of electromagnetic circuits are each disposed between two successive circuits () of the first plurality of electromagnetic circuits. A second element provided with at least one magnetic element is disposed between the two first elements.

Electromagnetic machine with optimized electromagnetic circuit elements integrated in tracks formed as crenellated annular lines

The invention relates to a turbine which can generate an electric current, comprising a motor and a stator. The rotor is formed by a blade having a permanent magnet mounted thereon. The stator includes first and second coils which are positioned close to one another and have substantially orthogonal winding axes, said coils co-operating with the permanent magnet in order to generate the electric current.

Electric current generating turbine

The invention relates to a turbine and to the implementation method thereof, said turbine comprising a blade mounted such that it can rotate about a central axis and an electromagnetic synchronous machine arranged with the blade in such a way as to modify the angular rotation speed of the blade in order to optimize the mechanical efficiency of the blade as a function of the speed of the incident fluid acting on the blade.

Hydrogenerator for boating

The miniaturized injection device () for medical use comprises a tube () extending along a certain axis (A-A) and in which there is disposed at least one reservoir () for receiving a medicinal substance, the reservoir being connected to at least one needle (). The needle is movable in the tube () along said axis (A-A) and the injection device () further includes a pump () interposed between the needle and the reservoir. The pump is controlled by a switch () that operates in response to the needle () moving in the tube along said axis (A-A).
