Equipment for influencing gas volume flows, method for control and/or regulation of an exhaust gas flow or a charge air flow, exhaust gas line and vehicle

The equipment comprises two gas pipelines, where the each gas pipeline includes different positions pivotable flap. The pivotable flap is connected with the former gas line through a valve, where the latter gas line is connected with the gas line through a rotation transmission device. A rotational movement of a flap (12) is transferred to another flap (22) during rotation of the former flap in an angular range and in another angular range. Independent claims are also included for the following: (1) a method for controlling or regulating an exhaust gas flow or a charge air flow; and (2) an exhaust gas system for use in internal combustion engine motor vehicles.
