Abstract
A water spray nozzle assembly includes an internal channel that is sealable by an internal valve having a seat and a disc. A tilting member is operable to tilt the disc at least partially off of the seat, allowing water to flow through the internal channel. The disc may be further tilted completely off of the seat to provide additional water flow through the water spray nozzle.
