Abstract

A valve includes a swirl-inducing arrangement positioned downstream from a valve seat. The swirl-inducing arrangement is shaped so that at least two radially offset and oppositely directed flows can be induced in a fluid to be sprayed. Swirl-induced shearing forces that cause turbulence occur in the boundary areas of the flow components having different directions. A uniform and extremely fine atomization of the fluid, specifically a fuel, is possible with this valve without any additional energy input. The valve is especially suitable for use in fuel injection.
