  • Coil compressed plunger cavity components for a wet type solenoid
    Patent number: 4044324
    Abstract: A wet plunger solenoid is formed with a three-piece spool assembly including a base and a hub joined by a nonmagnetic sleeve. An electric coil is wound directly onto the sleeve to compress the sleeve about the telescopically interfitted base and hub parts to form a fluid-tight joint, thus forming an armature or plunger cavity which has high resistance to deformation when fluid pressure is applied to the interior. A fluid-tight joint is formed which is free of threaded connections and is reinforced by reason of the fact that the coil is wound in tension, and the cumulative compression effectively joins the parts into a unitary structure.
