The valve includes a flat armature which is firmly connected with a movable valve element, embodied as a ball which cooperates with a fixed valve seat. The flat armature is provided on its side remote from the valve seat with recesses into which spring tongues formed from a remnant air disc protrude, resting under the influence of voltage on the flat armature and guiding it in parallel fashion.Field of SearchWITH SYSTEM FLUID RELIEF OR RETURN TO SUPPLYRecirculation within nozzle (e.g., burner nozzle cooling) Cooling of terminal element Coolant is spray fluid or is added to spray fluid DISTRIBUTOR HAVING THERMAL EXPANSION JOINT, DIFFERENTIALLY EXPANDING MATERIALS OR INSULATION Fuel injector or burner With discharge modifier* | |
