A rotary stream sprinkler unit comprises a housing 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 self-propelled 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 pressure compensated damping device in the housing connected to the rotary head by means of a shaft supported by a resilient member at the outlet for controlling the rotational velocity thereof.

A rotating stream sprinkler unit comprising: a tubular housing having a central axis, an inlet, an outlet, and a flow passage communicating therebetween for conducting a primary stream of water from said inlet to said outlet; distributor means rotatably mounted at said outlet for receiving said primary stream of water, for rotating in response thereto, and for directing said stream outward from the axis of said housing over a selected area; damping means including a damping fluid disposed in said housing up stream of said outlet and operatively connected to said distributor means by a rotatable shaft for controlling the velocity of rotation thereof; and means for equalizing pressure between said primary stream of water and said damping fluid.
