Beschreibung
Zusammenfassung:	The invention relates to a throttle valve device for an exhaust gas tract or an air intake tract of an internal combustion engine, comprising a throttle valve housing (30) which has an inner housing element (34) and an outer housing element (32) radially surrounding the inner housing element (34), an air gap (80) being provided between the outer housing element (32) and the inner housing element (34), and the inner housing element (34) radially delimiting a flow channel (36) and having a valve stop (38) projecting into the flow channel (36), said throttle valve device also comprising a throttle valve (40) which is arranged pivotably in the flow channel (36). In order to produce the throttle valve device simply and cost-effectively, the outer housing element (32) is produced from two outer housing half-shells (90, 92) and the inner housing element (34) is produced from two inner housing half-shells (94, 96).
