ABSTRACT:
An apparatus for reducing liquid flow rates includes a chamber having peripheral walls, one of the walls having an aperture therein. A conduit connected to the chamber at the aperture forms a path from the conduit into the chamber. A 3/32" (0.24 cm) thick rubber sheet mounted to the apertured wall has a circular orifice therein aligned with but smaller than the aperture in the wall. A stainless steel plate affixed to an upper portion of the wall also has a hole aligned with the orifice and the aperture and serves to clamp the flexible membrane to the wall. Liquid passing from the conduit to the chamber has its flow rate reduced by passing through the orifice in the flexible membrane. The flexible membrane can be bowed inward of the chamber under increased upstream pressures to form an interior conical portion to direct any entrained solids from the conduit into the chamber.
