Throttle valve assembly

The invention relates to a throttle valve housing comprising a housing having a continuous throttle hole that can be cross flown by a gaseous medium in a main flow direction, wherein said throttle valve shaft can be pivoted by an actuating drive and wherein the throttle hole is connected to an inlet line on the inlet side and to an outlet line on the outlet side. The invention aims at ensuring particularly reliable detection of the mass of gaseous medium coming in through the throttle hold, using particularly simple means. This is achieved in that a first temperature sensor for temperature T of the gaseous medium is arranged upstream of the throttle valve and in that a second pressure sensor for pressure P of the gaseous medium is arranged downstream of the throttle valve.
