Motor vehicle solenoid valve

A motor vehicle solenoid valve (10), comprising:

• a fixed body (20) intended to be mounted in a hydraulic system of the vehicle,
• a cylindrical coil support (40) mounted on said fixed body (20), the fixed body (20) extending along a longitudinal axis (X) in the coil support (40), the coil support comprising a first part extending along the longitudinal axis (X), a second top part extending radially from a top of the first part, and a third bottom part extending radially from a bottom of the first part,
• a mobile body (30) slidingly mounted in said fixed body (20) through said coil support (40),
• at least a first coil winding (50) arranged about the first part of the coil support (40) within the second top part and the third bottom part of the coil support (40), the at least a first coil winding (50) being suitable for generating a magnetic field for control of the sliding of said mobile body (30), the at least a first coil winding (50) having an outer surface, and
• a second coil winding (60) arranged about the outer surface of the first coil winding (50) in order to contain the magnetic field generated by said first coil winding (50), the first coil winding (50) and the second coil winding (60) being coaxial, the second coil winding located radially outside the second top and third bottom parts of the coil support (40) and extending from radially outside of the third bottom part of the coil support (40) to radially outside of the second top part of the coil support (40).
