A rotary stream sprinkler unit comprises a body having a water flow passage in which is disposed a flow control unit having one or more passages configured to control the volume and pressure of a stream which strikes and rotates a rotary distributor head rotatably mounted at the outlet of the housing for dividing each stream into a plurality of final streams and rotating each of the final streams through a selected arc during the rotation of the rotary head with a damping device connected to the rotary head for controlling the rotational velocity thereof.
