Abstract: A solenoid operated valve includes a valve block defining a valve lumen, a poppet slidably disposed within the valve lumen, a solenoid including an annular winding with an internal surface defining a winding lumen and an external surface, and a core including a central core portion disposed within the winding lumen and an annular core portion disposed outside the external surface of the winding, and an armature including a central armature portion disposed within the winding lumen and an annular armature portion disposed outside the external surface of the winding, wherein the armature is in communication with the poppet so that movement of one is translated into movement of the other. Solenoids for such valves are provided. Also provided are methods of assembling solenoid valves.

Abstract: A solenoid operated valve includes a valve block defining a valve lumen, a poppet slidably disposed within the valve lumen, a solenoid including a core defining a core lumen aligned with the valve lumen, and an armature assembly. The armature assembly includes an armature disc, an armature guide having a hollow cylindrical body defining an armature guide passage, and an armature stud disposed within the armature guide passage. The armature stud is in communication with the poppet so that axial movement of one is translated into axial movement of the other. The valve further includes a coil cover enclosing the solenoid, and a guard disposed to prevent contact between the armature assembly and an adjacent component of the valve. A method of assembling a solenoid operated valve includes placing a shim between the armature disc and the core, and pressurizing and energizing the valve.

Abstract: A mortar system includes a launch unit that comprises a mortar ignition cartridge provided with a flashtube. The flashtube incorporates a ring-like nozzle that is positioned within the flashtube, which acts to restrain the motion of the black powder pellets as well as to choke the flow of the resultant combustion products. The nozzle separates the flashtube into two compartments: a flashtube venting chamber and a pellet combustion chamber. The mortar ignition cartridge combustion chamber acts as the product-gas venting area of the flashtube. The combustion of the black powder pellets essentially takes place in the pellet combustion chamber. The present design modification improves the overall performance of the mortar system.
