Abstract
A fluid pressure regulator includes a diaphragm operated leakport controlling low liquid or fluid flow rates. A precisely formed leakage unit spaced from the leakport establishes continuous flow from the input to the output. The leakage unit includes an opening in the body of the regulator and a separate orifice unit having an integral molded body and internal precision orifice establishing the continuous flow. The molded body fits within the opening and is firmly attached to the body to create a precise control of flow therethrough. The orifice has a diameter in the range of about 0.001 to 0.030 inches, and establishes precise low flows. The separate orifice unit includes an elongated tubular body with an internal orifice molded as single integral members.
