ABSTRACT:
Apparatus for regulating the fluid flow produced from a gas pressurized subterranean reservoir. The produced mixture comprising crude oil, water, gas and varying amounts of particulated matter. The apparatus includes a bean which is characterized by a constant diameter flow passage, which limits the flow to a maximum rate. An adjustable valve positioned immediately upstream of the bean flow passage is adjustable to regulate the flow of pressurized fluid from its source, to a desired value less than the maximum level maintained by the bean. The apparatus is structured to allow ready access to the interior to facilitate replacement and repair of internal parts which may become worn or damaged due to constant wear and erosion by the flowing, abrasive fluid.
