摘要
A swirl spraying nozzle for spraying liquid fuel is provided. The swirl spraying nozzle includes a nozzle body including a hollow cylinder with a base terminating the hollow cylinder on one side and with a head terminating the hollow cylinder on the other side such that a swirl chamber is formed in the nozzle body. An admission hole is provided in the hollow cylinder in the vicinity of the base and is arranged in a plane perpendicular to the longitudinal axis of the hollow cylinder. The admission hole is positioned at an angle in the circumferential direction of the hollow cylinder. An outlet hole is provided in the head on the longitudinal axis of the hollow cylinder such that a liquid can flow tangentially through the admission hole with a swirling action into the swirl chamber and can flow out axially from the swirl chamber through the outlet opening.
