Abstract
An adjustable recirculation exhaust gas pressure differential venturi and coupler adapted to be coupled between an exhaust and an intake of an automotive-type engine and which receives exhaust gases from the exhaust for recirculation back through the intake. A valve having a chamfered orifice is located within the tubular coupler for controlling the flow of exhaust gases through the coupler thus controlling the pressure differential therein. The coupler is a two piece assembly with a telescopic connection which allows for axial and rotational adjustments.
