Magnet assembly for producing magnetic field for moving armature in cartridge of currentless closed magnet valve used in e.g. anti-lock braking system for vehicle, has winding embedded in magnetic, conductive plastic mixture forming housing

摘要

The assembly (2) has an electrical winding (22) i.e. copper wire, applied on a winding carrier (20). A housing (24) is formed from a magnetic conductive material. The electrical winding is embedded in a magnetic, conductive plastic mixture, which forms the housing. A paramagnetic substance and/or a paramagnetic substance compound and magnetic conductive metallic powder are added to the plastic mixture. A recess for an electrical contact (26) of the winding is provided in the housing. The winding carrier with the electrical winding is injection molded. Independent claims are also included for the following: (1) a magnet valve (2) a method for manufacturing a magnet assembly.
