Title: VALVE ARMATURE AND VALVE CARTRIDGE FOR A SOLENOID VALVE
Abstract:
The invention relates to a valve armature (10) for a solenoid valve, having a basic body (11) consisting of a magnetically conductive metal, on one end of which there is arranged a depression (14) which receives a tappet (20) having a closing element (24), wherein a tappet basic body (22) consists of plastic and forms an interference fit with the basic body (11), and to a valve cartridge (1) for a solenoid valve having such a valve armature (10). Here, the basic body (11) has an annular groove (16) which is connected to the depression (14), which annular groove receives plastic deformations of the tappet basic body (22) which form a form fit with the annular groove (16) and fix the tappet basic body (22) in the depression (14).
