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.
