Abstract
A pistol grip hose nozzle is disclosed which allows proportional water control in accordance with the position of a rotatable valve. The hose nozzle has a handgrip section with an inlet water passage and an outlet section with an outlet water passage. One end of the handgrip section is connectable with a hose. The other end of the inlet water passage ends in a valve seat with an aperture. The valve seat contains a valve having a flow control cylinder. The flow control cylinder has a non-circular opening which when aligned with the aperture allows water to flow to the outlet water passage. The flow control cylinder is attached to a control knob which allows a user to grip the hand grip portion and rotate the control knob and the flow control cylinder to vary the water flow. The non-circular opening allows the amount of water flow to the outlet water passage to be linearly proportional to the rotational position of the control knob.
