Pistol grip hose nozzle

A pistol hose nozzle (10) including a handle (12) structure and a barrel (14) structure extending forwardly from the upper end thereof. The handle (12) and barrel (14) structures are formed of two outer shell parts (18, 20) enclosing an inner conduit (16) providing a water flow path between an inlet at the lower end of the handle (12) structure and an outlet at the forward end of the barrel (14) structure. A spring actuated on-off valve mechanism (26) is disposed within the handle (12) portion of the flow path and a fixed orifice is disposed within the barrel (14) portion of the flow path. A variable leverage mechanism (30) serves to transmit the movement of a finger trigger (74) to the valve mechanism (26). A thumb actuated mechanism is provided for selectively retaining the trigger (74) in its operating position. Coupling means is provided in the forward end of the barrel structure and rearward tubular portions of an adjustable spray assembly and a rotary outlet assembly for enabling either to be detachably interengaged therewith.
