    摘要: A reciprocating engine (12) includes a cylinder head (68), a cylinder liner (42), an outer seal (100), and an inner seal (102). The cylinder liner has a flange (84) proximate to the cylinder head (68), where the cylinder liner extends circumferentially around a combustion chamber, and the cylinder head defines an end of the combustion chamber. The outer seal (100) is disposed between the flange of the cylinder liner and the cylinder head, where the outer seal is configured to transfer an axial compressive load between the cylinder head and the cylinder liner. The inner seal (102) is disposed between the cylinder liner and the cylinder head proximate to the combustion chamber. The inner seal (102) is configured to isolate an inner face of the outer seal from the combustion chamber. A first compressive strength of the outer seal is greater than a second compressive strength of the inner seal.

    摘要: Es wird eine Dichtungsanordnung für eine Verbrennungskraftmaschine mit einem Zylinderkopf (12), einem Zylinderblock (10), einer Zylinderlaufbuchse (14) und Dichtungsmitteln (24) beschrieben. Die Zylinderlaufbuchse (14) ist in einer Bohrung des Zylinderblocks (10) eingesetzt und stützt sich an diesem ab. Sie weist einen hohlen zylindrischen Teil (16), einen sich radial von dem zylindrischen Teil (16) nach außen erstreckenden ringförmigen Dichtungskragen (18), eine Kolbenbohrung (17) und eine im wesentlichen zum Zylinderkopf (12) weisende Kragendichtungsfläche (22) auf. Die Dichtungsmittel (24) stehen mit der Kragendichtungsfläche (22) und einer entsprechenden Zylinderkopfdichtungsfläche (23) in Eingriff, um den Austritt von Verbrennungsgasen aus der Kolbenbohrung zu verhindern. Um einem radialen Ausbruch der Dichtungsmittel (24) wirkungsvoll entgegenzuwirken, ohne daß überhöhte Klemmkräfte erforderlich sind, wird vorgeschlagen, wenigstens eine der beiden Dichtungsflächen (22) kegelstumpfförmig derart auszubilden, daß sie sich stetig von einer radial inneren umlaufenden Kante (26) zu einer radial äußeren umlaufenden Kante (28) erstreckt, wobei die radial innere Kante (26) weiter zu der anderen Dichtungsfläche (23) beabstandet ist als die radial äußere Kante (28). Der Neigungswinkel beträgt vorzugsweise etwa 2°.

    摘要: The invention is for a resilient sealing means for sealing between cylinder block and cylinder head of e.g. a combustion engine, where sealing problems arise with increasing pressure and temperature. The sealing means comprises a ring of resilient material, e.g. steel, having radial, cylindrical or conical sealing surfaces (3, 4), which form integral parts of the ring so that the surfaces are free to move with respect to each other.
    The cross section of the ring comprises two diagonally displaced U-shaped profiles (1, 2), where the free shanks each has a sealing surface (3, 4), which seals against the corresponding surfaces in grooves (7, 8) in those parts (5, 6) between which sealing shall be achieved. The ring is firmly anchored by the end surfaces of the shanks (9, 10).
    In another embodiment of the invention one U-shaped profile is substituted for by an L-shaped profile having a sealing surface which seals against the outer or inner periphery of a cylinder lining.

    摘要: A piston assembly including a piston body and a piston ring is provided. The piston body has a skirt, a portion of which extends circumferentially continuously and has a skirt diameter. The piston ring has a ring body which extends through at least one revolution in a generally helical shape when in a relaxed condition. The ring body also has an inner face, and when in the relaxed condition, the inner face presents a ring diameter which is less than the skirt diameter. The ring body circumferentially surrounds the skirt of the piston body, thereby causing the inner face to be biased into engagement with the outer surface of the circumferentially continuous portion of the skirt of the piston body to establish a dynamic seal between the ring body and the piston body.

    摘要: An arrangement in combustion engines comprises a cylinder (11), a cylinder head (12), cylinder head seals (16) and a scraper ring (17). An elastic scraper ring seal (23, 30) is provided close to either or both of the end surfaces (20, 21) of the scraper ring and separates volumes formed close to the scraper ring from the combustion chamber. Separating these volumes from the combustion space prevents the accumulation of residues of incompletely burnt fuel in these volumes. This makes it possible to improve the engines efficiency, reduce emission values and lengthen the engines service life.
