Elektroventil mit einstückiger Struktur aus ferromagnetischem Material

The electro-valve (1) has: - a admission (34,35) and escape pipe (34,35) for a fluid; - a mobile core (4) operates as a valv which permits as a function of its position blocking or circulation of the fluid between the admission and escape pipes (34,35); an electro-magnetic device controls the displacement of the core (4). The electro-magnetic device comprises: - a monolithic structure which is made from a ferro-magnetic material, in which are formed a cavity (21,31) used to lodge the core (4) and at l one of the two pipes (34,35), which end in the cavity (21,31); - at least an electrical conducting wire (5) which is wound on th monolithic structure, and which is designed to be fed with an electrical current, and; - at least an armature (A) made from ferromagnetic material which connects the two polar ends (24,3) of the monolithic structure.
