Abstract: The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the sleeve and thereby diminishes the quantity of liquid discharging from the nozzle.
