Patent ID: 8584768

Claim:
A firefighting nozzle assembly comprising: a nozzle body having an inlet, an outlet, and a passageway extending from said inlet to said outlet, said passageway having a flow area and a fixed diameter at said outlet; a lever supported at said nozzle body; an actuator, said actuator supported by said nozzle body; a movable body disposed in said passageway, said movable body supported for linear movement in said passageway, and being responsive to movement of said lever, and said movable body reducing the flow area through said outlet when said movable body is moved toward said outlet and increasing the flow area when moved away from said outlet, said movable body having a distal end and a proximal end, said distal end being closer to said outlet than said proximal end and being laterally movable within the passageway so that water flow through the passageway centers said distal end of said movable body in said passageway, and said movable body further comprising an elongate body with said distal end formed at one end of said elongate body and said proximal end formed at an opposed end of said elongate body, said proximal end being supported by a pin connection in said passageway wherein said distal end is pivotable with respect to said proximal end and is laterally movable in the passageway wherein fluid flowing in said passageway generally centers said movable body in said passageway; and a stream shaper, said stream shaper coupled to said movable body and moving with said movable body when said movable body is moved in said passayay in response to movement of said lever; said proximal end of said movable body is pivotally mounted to said stream shaper wherein said distal end of said movable body is laterally movable with respect said stream shaper.
