Pole tube for electromagnet i.e. proportional magnet, in hydraulic valve, has tubing element comprising tube piece that is connected with non-magnetic intermediate piece by thermally produced connecting layer or adhesive layer

摘要

The tube (1) has a tubing element (2) and a pole piece (3) that partially closes the tubing element. The tubing element has a tube piece (20) and a non-magnetic intermediate piece (21), where the tube forms an anchor area (10) for receiving an anchor. A tappet is mounted on a through opening (30), where the tappet cooperates with the anchor. A connecting piece (22) is provided in the tubing element. The tube piece is connected with the non-magnetic intermediate piece by a thermally produced connecting layer (4) e.g. solder joint layer, or an adhesive layer. An independent claim is also included for a method for producing a pole tube.
