摘要： A part-circle sprinkler incorporates a generally cylindrical housing and a popup nozzle head which rotates on a vertical axis in a step-by-step manner in response to successive impacts produced by weight members carried by an impeller. A stream of water is directed against the impeller by a deflector mechanism which is actuated by adjustable fingers rotatable with the nozzle head to reverse the direction of rotation of the impeller and the nozzle head. A sheet metal cover is mounted on the nozzle head and engages the housing when the head is retracted.
