The pressure regulator housing is incorporated into the center of the nozzle assembly and includes a reference pressure chamber connected to atmospheric pressure with a spring bias enclosed to bias a pressure responsive movable member that is connected to an upstream pressure balanced flow throttling valve. A combination deflector pop-up pressure regulating mechanism housed in the filter of the nozzle housing assembly is also shown.
