Abstract
This invention is a variable orifice for controlling the mass flow rate of nitrous oxide used as an engine oxidizer, this orifice having an effective size, or area, which changes with changes in the nitrous oxide pressure applied to it. Several design parameters can be changed to provide the desired effective orifice area as a function of pressure. This variable orifice can be designed to maintain an essentially constant nitrous oxide delivery rate over a wide range of nitrous oxide pressures.
