Abstract
The disclosure illustrates a turbocharger wastegate valve comprising a cylindrical chamber connected through a radial inlet to the gas stream upstream of the turbine. High pressure air is selectively directed across the inlet through a nozzle to prevent or permit flow into the chamber which is connected to a point downstream of the turbine. The pressure of the air delivered to the nozzle may be varied to proportion the gases bypassed around the turbine.
