Abstract
Spray nozzle for piston cooling of an internal combustion engine, whose cooling fluid outlet opening is formed with a discharge geometry which prevents the discharge of cooling fluid in an inner region lying within a hypothetical extension of the outlet opening and being surrounded by the cooling fluid otherwise being sprayed out, by a plurality of webs (10) penetrating the discharge cross-section of the outlet opening (15) in such a manner that the cooling fluid nozzle stream (12) being discharged fragments into individual partial jets (17), these being disposed around the inner region (7) being kept free of cooling fluid.
