Patent ID: 8221058

Claim:
A fresh gas system for supplying an internal combustion engine with a fresh gas, comprising: a charging device for increasing the pressure of the fresh gas; a swirl generator arranged upstream of the charging device for generating a swirl, which rotates about a main flow direction of the fresh gas, in the fresh gas; a plurality of guide blades included with the swirl generator each guide blade having an adjustable angle of incidence, the guide blades each having a first end portion, a radial inner portion, a second end portion and a radial outer portion; and a supporting web for supporting the first end portion of each guide blade, wherein the swirl generator has a flow guide body on which the guide blades radial inner portion is connected, and the guide blades are selectively twisted as increased flow forces act thereon, such that the guide blades elastically deform about the main flow direction starting from an undeformed initial position, thereby adjusting the angle of incidence in at least one of a positive and a negative direction.
