Abstract
A simplified, low cost, turbine flow controlling device, using a sliding gate, with an actuator to control exhaust flow to multiple volutes, which volutes have perforated transverse divider walls. By moving the sliding gate () from a closed position () through a displacement of 'a' to the next position b; and then from position bthrough a displacement of 'b' to the next position c, each a discreet movement, by a simple actuator, an increasing number of volutes are opened for flow from the exhaust manifold, via the volutes with perforated transverse divider walls, to the turbine wheel, without the attenuation of pulse energy usually seen in VTGs, at a cost lower than that of a VTG.
