Abstract:
An air-conducting device for internal combustion engines having a charge-air device, said air-conducting device comprising:a fresh-air pressure duct which opens into a compressor outlet duct of a compressor of the charge-air device, a fresh-air duct feeding fresh air; a compressor inlet duct; an orifice opening into the fresh-air duct and the compressor inlet duct; at least the fresh-air pressure duct and the orifice being connected to one another via a control element for metering air; and a compensating device being provided in order to compensate for forces which act on the control element on account of a pressure difference between gas a pressure (p3) at a pressure-gas side and a gas pressure (p2) at a fresh-gas side in such a way that the pressure difference does not lead to a force component which acts in the direction of opening or closing of the control element, wherein the gas pressure (p3) is defined at the fresh-air pressure duct and wherein the gas pressure (p2) is defined at the orifice.
