Abstract
The injection nozzle according to the invention for cooling the pistons of an internal combustion engine serves to produce a sharply bundled solid stream. In order to prevent separation of the oil stream at high oil temperatures and the associated low viscosity of the lubricating oil, it is proposed to provide at least two exit channels approximately parallel to one another, whose spacing is less than twice the diameter of the larger exit channel. With this design of two exit channels that are located very close together, an oil stream is produced that is a coherent solid stream a short time after leaving the exit channels.
