ABSTRACT:
A solenoid of the wet armature type for operating valves has the usual closed end tube within which a stationary pole piece and a slidable armature are mounted with a push pin extending through the pole piece. A bobbin-mounted energizing coil surrounds the tube. A generally barrel-shaped housing surrounds the coil and the tube. The housing has thick walls and is formed of magnetically permeable material to provide a low reluctance path extending substantially completely around the outside of the coil and along its two ends. The housing is formed in the plurality of sections spaced from one another along axial planes and clamped together against the tube by clamping members at either end. The housing is provided with conical clamping surfaces. The housing members are formed from sintered powdered magnetic iron.
