Air volume control device for selectively regulating exhaust gas stream from exit gas line to by-pass line of natural gas engine, has by-pass line arranged between valve housing and gas line, and valve disk arranged in by-pass line

摘要

The device has a valve disk (140) open or closed for selective rerouting of a portion of exhaust gas in a by-pass line (170), which flows from a natural gas engine to a turbine (300) of a turbocharger. A valve rod (130) connected with the valve disk is inserted into a valve housing (160). A control drive (100) includes a control drive housing (110), and is fastened to the valve housing by an attachment carrier (121). The by-pass line is arranged between the valve housing and an exit gas line (200), and the valve disk is arranged in the by-pass line.
