ABSTRACT:
A turbine operated rotary sprinkler comprising a rotary nozzle, a water supply, operated turbine and rotary drive coupling means coupling the turbine to the nozzle so as to impart a rotary drive thereto, the turbine comprising a turbine wheel having a plurality of equiangularly distributed vanes each having a plane of symmetry located along a radial plane of the wheel, a pair of turbine inlets being located with respect to the wheel that water inflow sequentially through the inlets drives the wheel in respectively opposite senses, sealing means being provided for sequentially sealing the turbine inlets, displacement means being provided for displacing the sealing means into sequentially sealing the turbine inlets, displacement actuating and transmission means being provided which comprise an impact member and a rotational range defining member, the latter including a pair of spaced apart abutment elements, one of the members being rotatable with the nozzle and the other of the members being responsively coupled to the displacement means for displacing the sealing means into sequentially sealing the turbine inlets in accordance with which abutment element is contacted by the impact element, and range variation means for ranging the spacing apart of the abutment elements.
