Claims
- 1. An electromagnet system having an electromagnetic coil, said system comprising:
- an insulated coil form for supporting said electromagnetic coil;
- a core element of a ferromagnetically conductive material inserted within said insulated coil form;
- a pair of substantially flat ferromagnetically conductive pole pieces overlying the ends of said insulated coil form and having cylindrical apertures formed therein for receiving the respective end of said core element, a portion of said pole pieces extending beyond said coil form, said flat pole pieces and said core element forming a magnetic flux element; and
- circuit means, located in a flange of said insulated coil form between and thermally coupled to both said electromagnetic coil and an adjacent pole piece of the magnetic flux element, for preventing overheating of said electromagnetic coil and the pole pieces of said magnetic flux element.
- 2. An electromagnet system according to claim 1, wherein said circuit means is a thermal fuse, which is destroyed when the limiting value of the overheating protection is exceeded.
- 3. An electromagnet system according to claim 1, further comprising:
- a dipper armature made of ferromagnetically conductive material located between free ends of said flat pole pieces, said dipper armature adapted to be used as a dosing valve, for measuring beverage concentrate.
