Description
Die Erfindung betrifft einen Großmotor, insbesondere einen Zweitakt-Großdieselmotor mit einem von einem gasförmigen Medium durchströmbaren Kanalsystem, das wenigstens einen mittels einer zugeordneten Klappe verschließbaren Strömungsdurchgang aufweist.The Invention relates to a large engine, in particular a two-stroke large diesel engine with one of a gaseous Medium permeable Channel system, the at least one by means of an associated flap lockable Flow passage having.

Die JP 2000-038180 AA zeigt eine im Ladeluftkanal eines Motors angeordnete, durch den Druck der Ladeluft entgegen der Schwerkraftwirkung um eine horizontale Achse schwenkbare Klappe. Hier ist ein hoher Druck erforderlich, um die Klappe anzuheben.The JP 2000-038180 AA shows a arranged in the charge air duct of an engine, by the pressure of the charge air against the force of gravity around one horizontal axis swiveling flap. Here a high pressure is required to lift the flap.
Die
Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung, eine Anordnung gattungsgemäßer Art mit einfachen und kostengünstigen Mitteln so zu verbessern, dass jede Klappe bereits bei vergleichsweise geringem Öffnungsdruck geöffnet und selbsttätig zuverlässig geschlossen wird.Of these, It is therefore the object of the present invention to provide a Arrangement of the generic type with simple and inexpensive Means to improve so that every flap already at comparatively open and low opening pressure automatic reliable is closed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jedem Strömungsdurchgang, der im Bereich einer stehenden Wand vorgesehen ist, eine eigene Klappe mit randseitiger Schwenkachse zugeordnet ist, die einen gegenüber der stehenden Wand geneigten, von der vertikalen Richtung abweichenden Verlauf aufweist.These Task is inventively characterized solved, that every flow passage, which is provided in the area of a standing wall, its own Flap is assigned with edge-side pivot axis, which is opposite to the standing inclined wall, deviating from the vertical direction History has.
Mit diesen Maßnahmen werden die eingangs geschilderten Nachteile der bekannten Anordnungen vollständig vermieden. Der gegenüber der stehenden Wand geneigte Verlauf der Schwenkachse der Klappe stellt sicher, dass bereits ein vergleichsweise geringer Öffnungsdruck genügt, um die Klappe zu öffnen und diese dennoch aufgrund ihres Gewichts automatisch in die Schließstellung zurückkehrt. Eine Schließfeder wird in vorteilhafter Weise nicht benötigt. Die erfindungsgemäßen Maßnahmen ergeben daher eine besonders einfache und kostengünstige Anordnung.With these measures The initially described disadvantages of the known arrangements are completely avoided. The opposite the vertical wall inclined course of the pivot axis of the flap Ensures that already a comparatively low opening pressure enough, to open the flap and these still due to their weight automatically in the closed position returns. A closing spring is not needed in an advantageous manner. The measures according to the invention therefore give a particularly simple and inexpensive arrangement.
Vorteilhafte Ausgestaltungen und zweckmäßige Fortbildungen der übergeordneten Maßnahmen sind in den Unteransprüchen angegeben.advantageous Embodiments and appropriate training the parent Measures are in the subclaims specified.
Eine besonders zweckmäßige Anwendung der erfindungsgemäßen Maßnahmen ergibt sich im Bereich der Ladeluftversorgungseinrichtung eines Großmotors, dessen Ladeluftbehälter wahlweise mittels eines Abgasturboladers und wenigstens eines Zusatzgebläses mit Ladeluft beaufschlagbar ist. Dabei sind zweckmäßig vom Abgasturbolader und von jedem Zusatzgebläse kommende, getrennte Strömungsäste über jeweils einen Durchgang, dem eine eigene Klappe zugeordnet ist, an eine nachgeordnete, mit der Ladeluftleitung verbundene Kammer angeschlossen, wobei die genannten Durchgänge jeweils in einer stehenden Wand angeordnet und die Schwenkachsen der Klappen gegenüber dieser geneigt sind. Dabei stellen die erfindungsgemäßen Maßnahmen sicher, dass keine Falschluft angesaugt wird.A particularly expedient use of inventive measures results in the area of the charge air supply device of a large engine, its charge air tank optionally by means of an exhaust gas turbocharger and at least one additional blower with Charge air can be acted upon. It is useful from the exhaust gas turbocharger and from each auxiliary fan coming, separate flow branches over each a passage, which is assigned its own flap, to a connected downstream, connected to the charge air line chamber, wherein said passages each arranged in a vertical wall and the pivot axes the flaps opposite these are inclined. Here are the measures of the invention sure that no false air is sucked.
