Abstract: A sprinkler device including a body on which a tubular spindle is mounted for rotation about a rotational axis relative to the body. The spindle has a fluid inlet in the region of the body and includes a slanted portion projecting from the body at an angle to the rotational axis. A head is rotatably mounted on the slanted portion of the spindle in engagement with the body and includes a fluid discharge member which communicates with the interior of the tubular spindle. The slanted portion of the spindle and the engagement of the head with the body are such that when the spindle rotates relative to the body, the head and the discharge member rotate relative to the body about the rotational axis and also oscillate in a longitudinal direction with respect to the rotational axis during rotation about the rotational axis.
