ABSTRACT:
An integrally molded, elastomeric fluid flow restrictor for use in pipes to even the volumetric time rate of flow of fluid through a pipe regardless of applied fluid pressure. The restrictor has a flow passage orifice which elastically responds to compressional fluid pressure to vary in size inversely to applied pressure. The restrictor includes integrally attached to the main body upstream and downstream annular flanges of an outer diameter less than the main body diameter, thereby defining a shoulder on the main body, and the flanges have an inner diameter larger than the flow orifice. The shoulder of the main body is beveled slightly inward to seat against a fitting to provide a tight seal in actual operation. A fitting adapted to the restrictor which fits into a hydraulic system is also disclosed.
