Abstract

1,055,490. Electromagnets. DANFOSS A/S. Oct. 5, 1964 [Oct. 5, 1963], No. 40566/64. Heading H1P. The return magnetic path on the outside of the coil 7 of a plunger type electromagnet is formed by magnetic particles embedded in a firm carrier material. As shown, the coil is embedded in a cup 16 of magnetic powder in a plastic carrier having an annular extension 19 into a recess 20 in the core 8 or between the core and an armature non-magnetic tube if provided. Inserted in a core recess 10 are two iron halfbushes 11, 12 and two plastic half-bushes 13, 14, and an electrically insulating layer 15 surrounds the coil. In modifications, the cup alternatively may comprise sequential layers of lacquer and iron powder applied to the coil, or be produced, in a mould or by immersion. The electromagnet is shown used with a valve.
