<p>1. Electromagnetic pump for conductive liquid with backflow by means of magnetic repulsion, comprising an annular duct (10) which receives the conductive liquid, coil means (11) and a magnetic circuit (12) for creating a magnetic field and an electric current in the conductive liquid, characterised in that : - the annular duct (10) is closed at one end and communicates, in the vicinity of this end, with a lateral intake duct (16) for the conductive liquid, the other end of the annular duct (10) being open and communicating with an outlet duct, - the coil means (11) comprises a single winding which is coaxial with the annular duct (10) adjacent to the closed end thereof and supplied with singlephase alternating current, - and the magnetic circuit (12) surrounds both the coil means (11) and the annular duct (10), on the inside and outside.</p> |
