Abstract
The rotating sprinkler head valve includes an upper assembly with a stationary rigid cone received in a conical interior chamber of a rotor, and a cylindrical shaft extending through the stationary rigid cone and rotor. A lower assembly includes a bottom helix member, a strainer adapter having an internal transverse slotted plate and a rotatable slotted flow plate to permit flow when the flow plate slots are aligned with slots in the internal transverse slotted plate. A base top member includes 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 the bottom helix member, and a recessed inner helical lip is configured to receive the upper helical surface of the bottom helix member for adjusting a helical aperture.
Claims15
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 tubular base top member including a downwardly extending inner tubular portion, said tubular base top member forming an adjustable aperture in cooperation with said bottom helix member, and said base top member including a cylindrical aperture therethrough;
- 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, and said longitudinal aperture of said bottom helix member, and said rotor being rotatable with respect to said cylindrical shaft.
