Abstract (en)
[origin: DE10010272A1] The drive has a rod-shaped actuator carrying a magnet armature and connected to the free end of the valve shaft to transfer force. Valve and actuator shafts have grooved end notches engaged by conventional conical valve parts enclosed by sleeves with inner cones. The sleeves engage each other via threaded fittings and are axially movable to exert radial forces on the conical parts. A deformable distance ring produces a restoring force. The drive has a rod-shaped actuator carrying a magnet armature and connected to the free end of the valve shaft so as to transfer force. The ends of the valve and actuator shafts (1,3) have grooved notches (2,4) in which conventional conical valve parts (5,6) engage. The conical parts are enclosed by sleeves (7,8) with inner cones (9,10). The sleeves engage each other via threaded fittings (11,12) and are axially movable to exert radial forces on the conical parts. A deformable distance ring (13) between the conical parts produces a restoring force.
