Abstract
In the combination of an internal combustion engine, a turbocharger and a ste gate, the improvement is the waste gate which includes a fluidic device having its inlet and outlet connected in parallel with the turbine of the turbocharger and a biasing port responsive to the output of the turbocharger to proportion the fluid flow from the inlet to the outlet between two parallel fluidic paths having a high and low flow resistance respectively. The fluidic device is a fluid amplifier providing radial and tangential flow to a vortex valve to produce the low and high resistance fluidic paths respectively. Alternatively, the fluidic device could be in series with the turbocharger to backpressure the compressor of the turbocharger.
