Description
Ölmotorenkolben Die Erfindungbezieht sich auf einenÖ1motorenkolben mit einem als Schale ausgebildeten Hohlraum, der mit dem Zylinderraum durch einen in einem Deckel enthaltenen Drosselquerschnitt verbunden ist.Oil engine piston The invention relates to an oil engine piston with a cavity designed as a shell, which is connected to the cylinder space by a Throttle cross-section contained in a cover is connected.
Gemäß der Erfindung ist der Deckel in die obere Öffnung der Schale eingesetzt und mit seinem Rand unmittelbar mit der Schalenwand selbst verbunden, z. B. "urch Einschrauben oder Einschweißen, so daß beim Undichtwerden dieser Verbindung keine Gase aus dem vom Zylinderraum und Kolbenhohlraum gebildeten Verdichtungsraum entweichen können, wie dies bei den bisher bekannt gewordenen Kolben der angegebenen Art vorkommt. Die unmittelbare Befestigung des Deckels ergibt überdies einen äußerst einfachen Kolbenaufbau.According to the invention, the lid is in the upper opening of the bowl inserted and connected with its edge directly to the shell wall itself, z. B. "by screwing in or welding, so that if this connection leaks no gases from the compression space formed by the cylinder space and piston cavity can escape, as is the case with the previously known pistons of the specified Type occurs. The immediate attachment of the lid also gives an extremely simple piston structure.
Auf der Zeichnung sind in den Abb. i bis 3 Ausführungsbeispiele des Erfindungsgegenstandes jeweils im Längsschnitt dargestellt.On the drawing are in Figs. I to 3 embodiments of the Subject of the invention shown in longitudinal section.
Beim ersten Beispiel nach Abb. i ist der Kolben mit a bezeichnet. Er besteht aus Gußeisen. Der Boden b des Kolbengußstückes ist schalenartig ausgehöhlt und auf seiner Oberseite bearbeitet. In der Gegend des oberen Randes der Kolbenbodenhöhlung ist ein Gewinde eingeschnitten, in das ein an seinem Rand ein entsprechendes Gegengewinde tragender Deckel c eingeschraubt ist. Dieser besteht aus Kohlenstoffstahl und hat in seiner Mitte eine enge Öffnung d als einzige Verbindung zwischen dem über dem Deckel vorgesehenen Trichterraum e und dem unter dem Deckel entstandenen Kolbenhohlraum f. Die Oberseite des Deckels enthält den größten Teil des Trichterraums.In the first example according to Fig. I, the piston is denoted by a. It is made of cast iron. The bottom b of the piston casting is hollowed out like a shell and worked on its top. In the area of the upper edge of the piston crown cavity a thread is cut into which a corresponding mating thread on its edge bearing cover c is screwed in. This is made of carbon steel and has in its center a narrow opening d as the only connection between the above Cover provided funnel space e and the piston cavity created under the cover f. The top of the lid contains most of the funnel space.
Beim zweiten Ausführungsbeispiel nach Abb. 2 ist der aus Stahl hergestellte Kolbenboden b als Schale ausgebildet und mit dem Rand in den oberen Rand des aus Eisen- oder Leichtguß bestehenden Kolbenmantels a eingeschraubt. Der den Hohlraum f abscheidende Deckel c enthält auch hier die enge Öffnung d. Er wird an seinem Rand mit der den Kolbenboden b bildenden Schale verschweißt, nachdem die von der Schale gebildeten Wände des Hohlraums f vorher maßhaltig bearbeitet worden sind. Der dem Kolbenhohlraum f vorgeschaltete Trichter e ist teils in der Oberseite des Deckels, teils im Randteil des Kolbenbodens enthalten.In the second embodiment according to Fig. 2, the piston head b made of steel is designed as a shell and screwed with the edge into the upper edge of the piston skirt a made of iron or light cast. The cover c separating the cavity f also contains the narrow opening d here. It is welded at its edge to the shell forming the piston head b, after the walls of the cavity f formed by the shell have previously been machined true to size. The funnel e upstream of the piston cavity f is contained partly in the top of the cover and partly in the edge part of the piston head.
Das dritte Ausführungsbeispiel nach Abb.3 unterscheidet sich von dem soeben beschriebenen nur dadurch, daß der Deckel c wie beim ersten Beispiel eingeschraubt ist und daß der als Schale ausgebildete Kolbenboden an seinem Rand im oberen Kolbenmantelrand eingegossen ist. Gleichzeitig ist auch eine den unteren Teil der Kolbenbodenschale mit einem Abstand umschließende Blechschale g mit eingegossen.The third embodiment according to Fig.3 differs from that just described only in that the cover c is screwed in as in the first example and that the piston head, which is designed as a shell, is at its edge in the upper edge of the piston skirt is poured. At the same time there is also one of the lower part of the piston crown shell with a spaced enclosing sheet metal shell g cast in.
