Abstract:
1. A rotating sprinkler head valve, comprising: a cone member having a central aperture; a rotor having a central aperture, said rotor being rotatable with respect to said cone member; a generally tubular bottom helix member having a top end and a bottom end, said generally tubular bottom helix member having a longitudinal aperture therethrough, an upper helical surface extending substantially completely around the upper narrow tubular section, and a vertical flag extending upwardly from the upper helical surface of the bottom helix member; a generally tubular strainer adapter having an interior tubular chamber extending through said generally tubular strainer adapter, an internal transverse slotted plate extending transversely across said interior tubular chamber, said internal transverse slotted plate including at least one slot configured to allow flow through the strainer adapter; a flow plate received in and extending transversely across said interior tubular chamber of said generally tubular strainer adapter, said flow plate including at least one slot configured to permit flow through said interior tubular chamber when aligned with said at least one slot of said internal transverse slotted plate; a tubular base top member including a downwardly extending inner tubular portion and a lower interior edge surface with a helical lower surface forming an adjustable helical aperture in cooperation with said bottom helix member, and said base top member having an interior surface defining a recessed inner helical lip along said lower interior edge surface of the downwardly extending inner tubular portion, said recessed inner helical lip configured to receive said upper helical surface of the bottom helix member and said recessed inner helical lip being rotatable with respect to said upper helical surface of the bottom helix member for adjusting said helical aperture; and a cylindrical shaft having an upper end and a lower end, said cylindrical shaft extending vertically and axially through said central aperture of said cone member, said central aperture of said rotor, said longitudinal aperture of said bottom helix member, and said generally tubular strainer adapter, said flow plate central aperture being configured to receive and engage said lower end of said cylindrical shaft, and said rotor being rotatable with respect to said cylindrical shaft.
