Abstract
The invention relates to a gas conducting device for internal combustion engines, notably motor vehicle engines, comprising a pressure line ( ), a fresh-gas line ( ) supplying fresh gas, a discharge line ( ) and an orifice ( ) which opens into the fresh gas line ( ) and the discharge line ( ). At least the pressure line ( ) and the orifice ( ) are connected via a control element ( ) for the metered addition of gas. A compensating unit ( A; A; ) is provided for so as to compensate forces which act on the control element ( ) as a result of a pressure difference (p -p ; p -p ) between the gas pressure on the compressed gas side (p ; p ) and the fresh gas side (p ; p ).
