SPRINKLER Russian patent published in 2007 - IPC A01G25/02 

FIELD: agricultural engineering.

SUBSTANCE: sprinkler comprises housing, guiding rod, fluoroplastic spacer, conical deflector, adjusting nut, and locking nut. The hollow cylindrical housing is provided with the baffle. The baffle is provided with the guiding rod that is mounted coaxially to the housing. The conical deflector with curved diverging grooves provided on its surface is set on the guiding rod for permitting rotation around the rod and movement along the rod. The movement of the deflector is arrested by adjusting nut and lock nut screwed on the threaded section of the guiding rod. The fluoroplastic spacer is mounted on the guiding rod between the adjusting nut and conical deflector. The step cylindrical spaces are made in the conical deflector whose axes are in coincidence with the axis of rotation. The pair of oppositely oriented slide bearings is set in the small-diameter space for permitting rotation around the guiding rod. The space of intermediate diameter receives a flexible member made of a compression spring. The first face of the flexible member cooperates with the fluoroplastic spacer mounted on the rod from the side of the baffle. The second face of the flexible member bears on the slide bearing of the conical deflector. The large-diameter space receives the adjusting nut that represents a pivot. The small-diameter space is connected with the large-diameter space through passages parallel to the axis of rotation of the conical deflector.

EFFECT: enhanced reliability.
