ELECTROMAGNET FOR OPERATION IN PRODUCT IN CONDITIONS OF INCREASED PRESSURE OF ENVIRONMENT Russian patent published in 2010 - IPC H01F7/06 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and is provided for activation of mechanisms, which are in liquid or gaseous medium under increased pressure. Electromagnet for operation in product in conditions of increased pressure of environment contains casing. In casing it is installed spring loaded rotor, coil, casing, lead-outs. Casing closes magnetic circuit. On external surface of radial surface of casing nearby butts there are implemented annular grooves. In grooves there are located closure elements. Ends of lead-outs of coil are taken out through groove in wall of casing into isolated from environment cavity of product. Rotor is rigidly connected to rod. Rod passing through reach-through central hole of casing. Head of rod is supported by spring cogged by screw nut. Head of rod, spring and screw nut are located in open butt cavity of casing.

EFFECT: reliability growth of electromagnet operation in conditions of increased pressure of environment.
