Proportionally acting electromagnet for cam shaft adjustment device of internal combustion engine, has seal sealing radial gap between electromagnet and housing and coordinated to small axial assembly force

摘要

The electromagnet (1) has a plastic over molding part (2) comprising a flange-sided mold element (4) and a housing-sided mold element (12) holding the electromagnet. Metallic springs (5) carry over axial bias for bearing the electromagnet and springy locking to hold a twist layer. Bias forces of the springs are produced for bearing the electromagnet and locking by rotation of the electromagnet during assembly of bevels (7) at the mold elements. A seal seals a radial gap between the electromagnet and housing (11) and is coordinated to small axial assembly force by design of the housing. An independent claim is also included for a method for assembly of a proportionally acting electromagnet.
