Patent ID: 7926271

Claim:
A fresh gas supply device for a turbocharged piston internal combustion engine having fresh gas conduction elements, comprising: a compressed air connection operatively connected to a tubular interior chamber of the fresh gas conduction elements; a quantity regulating device for continuously regulating additional compressed air into the interior chamber; an adjustable flap arranged in the interior chamber for continuously regulating a throughflow, the interior chamber being bounded by a first end connection for inflow of charge air from an exhaust gas turbocharger, and by a second end connection for outflow of charge air from the exhaust gas turbocharger, the adjustable flap being adjustable between a fully opened end position and any desired intermediate position between open and closed positions; a common housing of the fresh gas conduction elements forming a separate module, the common housing defining the first and second end connections as line connections which are in addition also usable as supporting elements for the module, wherein an electrical terminal for an integrated electronic control unit is disposed on an outside surface of the common housing; and a first pressure pickup having a pressure meter arranged in the tubular interior chamber between the flap and the first end connection, and a second pressure pickup having a pressure meter arranged in the tubular interior chamber between the flap and the second end connection, the first and second pressure pickups being operatively connected to the electronic control unit, an exchangeable, flow-influencing throttle installable upstream of the quantity regulating device in the common housing, wherein the adjustable flap is the throughflow regulating flap in the interior chamber of the common housing, the quantity regulating device for the additional compressed air, an adjustment device for the flap and a position determining device assigned thereto are disposed within the common housing, the common housing has a connection face to which a cover is detachably attached, an electronic control unit which at least actuates the quantity regulating device and the adjustment device being arranged under the cover, and the throttle has a geometric axis substantially parallel to a geometric axis of the tubular interior chamber.
