Abstract: A pressure washing system that includes a pump configured to generate a pressurized fluid stream and a wand that is connectable to the pressurized discharge of the pump. The wand includes a trigger and a nozzle that are exposed to the pressurized fluid path. The wand includes a treatment fluid path that is isolated from the pump pressurized fluid path. A reservoir configured to receive a treatment agent is disposed in the treatment fluid path and is connected between the water source and an outlet proximate the nozzle. A control is connected to the wand proximate the trigger to allow selective introduction of treatment agent contained in the reservoir to be introduced into the pressurized fluid flow downstream of the nozzle.

Abstract: A nozzle assembly and method of forming an adjustable spray pattern nozzle assembly that is usable with pressure washing systems includes a first body and a second body that are positionally secured relative to one another. The first body includes a fixed shaped orifice that defines the exit of a fluid spray from the nozzle assembly. The second body is disposed upstream of the first body and includes a pressure dependent variable shape orifice. The second body is formed of a resilient material that allows flexure of the second body in response to pressure of the fluid flow. Flexure of the second body manipulates the shape of the variable shape orifice and thereby allows the nozzle assembly to provide various spray patterns without user manipulation of the nozzle assembly.
