A water sprinkler, comprises a distributor head and a direction-reversing member movably mounted with respect to the distributor head. The latter member includes first and second surfaces impinged by the water jet in first and second positions of the direction-reversing member, a third surface contactable with the distributor head for rotating it in one direction when the first surface is impinged by the water jet, and a fourth surface contactable with the distributor head for rotating it in the opposite direction when the second surface is impinged by the water jet. The sprinkler further includes an abutment, and a pair of stops engageable by the abutment after the distributor head has been rotated a predetermined distance in the one or opposite direction, to switch the direction of rotation of the distributor head.

A water sprinkler, comprising: a nozzle connected to a water supply pipe and discharging the water in the form of a water jet; a distributor head mounted on the sprinkler for rotary movement with respect to the nozzle and formed with a passageway aligned with the nozzle to receive the water jet therefrom and to direct it outwardly of the sprinkler; a direction-reversing member pivotally mounted at one end to the distributor head, and including at its opposite end a first surface impinged by the outwardly directed water jet in a first position of the direction-reversing member, and a second surface impinged by the outwardly directed water jet in a second position of the direction-reversing member; said direction-reversing member further including a third surface contactable with said distributor head for rotating it in one direction when said first surface is impinged by the water jet, and a fourth surface contactable with said distributor head for rotating it in the opposite direction when said second surface is impinged by the water jet; an abutment mounted on said opposite end of the direction reversing member; a first stop engageable by said abutment after the distributor head has been rotated a predetermined distance in said first direction, and effective to move said direction-reversing member from said first position to said second position; and a second stop engageable by said abutment after the distributor head has been rotated a predetermined angular distance in said opposite direction, and effective to move said direction-reversing member from said second position to said first position to rotate the distributor head in said first direction.
