Proportional magnetic valve

The proportional magnetic valve has an electromagnet with an armature that is movable in a housing (2) and with which a piston (6) can be moved in a bush (20) depending on a current. There is at least one component (34) that can be deformed in the axial direction of the piston arranged between the bush and the housing. The component can be elastically deformable or plastically deformable.
