ABSTRACT:
A surge chamber has an outflow/inflow control fitting on its bottom so as to make maximum use of fluid in the chamber. The fitting itself includes a surge pipe section and outlet pipe section extending downwardly from the bottom of the chamber and having companion flanges. An annular nozzle member is positioned between the flanges and defines a reduced diameter opening. This opening is designed to pass fluid from the chamber to a pipeline to prevent fluid separation of the fluid column in the pipeline to prevent fluid separation of the fluid column in the pipeline should the normally provided pumping system fail. The fitting further includes a core member supporting anti-vortex blades and a deflection plate to minimize agitation of the fluid/air surface in the surge chamber as might otherwise occur during outflow and inflow of fluid.
