Embodiment Construction
[0016] figure 1 An exemplary embodiment of a metering valve 100 according to the invention is shown in longitudinal section. The metering valve 100 has a valve housing 12 in which an inner chamber 26 is formed. An electromagnet 130 comprising a solenoid coil 13 , an inner pole 10 and an outer pole 11 is arranged in the inner chamber 26 . In this case, the inner pole 10 is connected to the valve housing 12 via a spacer bushing element 14 made of a non-magnetic material.
[0017] Furthermore, in the armature chamber 9 contained in the inner chamber 12 there is an armature 6 which is movable back and forth with a rod-shaped element 5 , wherein the rod-shaped element 5 is fixedly connected to the electromagnetic armature 6 and not only the notch 27 of the inner pole 10 and is received and guided in the notch 28 of the valve housing 12 . The armature 6 is designed as a plug-in armature and is received in a recess 22 of the inner pole 10 during its stroke movement.
