Abstract
A dual component injector, especially for internal combustion engines, has a nozzle body, which has a nozzle outlet, and a valve needle for opening and closing the nozzle outlet. A first feed channel is used for supplying a first fluid to the nozzle outlet, and a second feed channel is used for supplying a second fluid to the nozzle outlet. Optionally, a fluid chamber, which is located in the nozzle body, is connected to the nozzle outlet. The second feed channel is connected to the fluid chamber or to the first feed channel via at least two bored holes. The bored holes open out in the fluid chamber or in the first feed channel in such a way that the second fluid produces a swirling flow pattern in the fluid chamber or in the first feed channel.
