Abstract
Flow modulator () for a fluid like combustion gas, comprising: a housing (), a modulator body () positioned with the housing (), and a valve body () positioned with the housing (). The modulator body () has a flow channel () and an opening () providing together a flow passage () for the fluid. The valve body () is provided by a foil element (), wherein the foil element () has an opening () for the fluid, wherein the foil element () is rotatable relative to the modulator body () to modulate the flow of the fluid by adjusting an overlap between the opening () of the valve body () and the flow passage () of the modulator body (), and wherein the foil element () is positioned up-stream of the modulator body () such that an inlet pressure of the fluid presses the foil element () against the modulator body () thereby providing a sealing level between the foil element () and the modulator body ().
