摘要:
An electromagnetic hydraulic valve (1) is provided having a valve housing (2) with a pressurized hydraulic medium inlet channel (24), a pressurized hydraulic medium outlet channel (25), a magnet coil (3), and a valve seat (23), with a magnet armature (9) that can be excited by the magnet coil and a valve tappet (10, 10′) fixed on this armature. A valve-closing element (13) is activated by the valve tappet and that blocks the connection between the pressurized hydraulic medium channels for contact on the valve seat. The magnet armature with the valve tappet and the valve-closing element are guided so that they can move longitudinally in the valve housing and the valve tappet and the valve-closing element contact each other with facing longitudinal end sides (26, 27) in a way that is free from tensile forces. Here, one annular, continuous lobe or several lobes (28, 28′) separated from each other are formed on the longitudinal end side of the valve tappet, which span a contact plane running perpendicular to a longitudinal direction of movement for the longitudinal end side of the valve-closing element.
