    摘要: This invention relates to a mounting structure of a multiple piston ring for various internal combustion engines. A plurality of piston rings (PR1, PR2, PR3) are all wrapped in a cylindrical groove formed upon an outer surface of a piston (P) so that a gap of one piston ring cannot face to a gap (EX1 or EX2) of the other piston ring, namely respective gaps of the plurality of piston rings are spaced with each other with a certain distance. In order to prevent such a facing of two or more gaps (EX1, EX2) that may occur due to a rotation of the piston rings, a stop pin (3) is mounted on a piston wall so as to engage with a gap of one piston ring or formed as a convex protrusion on one piston ring so as to engage with a gap of the other piston ring. Since respective gaps of the piston rings are not faced to each other, it is possible to prevent any back pressure gas leakage from such gaps of the piston rings.

    摘要: Anti-rotation device (15) consists of a thin washer (16) having a pair of circumferentially and radially spaced tabs (19, 20) protruding axially from one side thereof which are adapted to be received in the gaps (10, 11) in the inner and outer rings (5, 6), respectively, of a circumferential ring seal (1) to prevent the gaps (10,11) from aligning themselves. The tabs (19, 20) are desirably located approximately 180° apart to keep the ring gaps (10,11 ) on diametrically opposite sides of the seal (1).

    摘要: A seal ring including a body having an inner surface, an outer surface, and a first side surface, and a tab extending from the body and adapted to prevent rotation of the seal ring relative to a component receiving the tab, wherein the tab extends radially inward beyond the inner surface and axially beyond the first side surface. In an embodiment, the seal ring further includes a relief portion adapted to accommodate a tab of an adjacent sealing ring such that the first side surface of a seal ring directly contacts the second side surface of the adjacent seal ring. In an embodiment, the tab locks the seal ring from rotational movement in relation to a first component.

    摘要: The present invention relates to a seal unit (10) suitable to be inserted in the first groove (20') of a piston (20) of an internal combustion engine. The seal unit (10) according to the invention comprises a first ring-shaped body (10') which defines a first gap section (12') and a second ring-shaped body (10'') which defines a second gap section (12''). According to the invention such bodies are overlapping so that the position of said first section (12') is different from the position of said second section (12'') in relation to a reference axis (101) to which the two bodies (10',10'') are coaxial.

    摘要: Um ein Eindringen von Schmiermittel in den Brennraum zu verhindern, wird ein Kolben für eine Brennkraftmaschine vorgeschlagen, bei dem eine labyrinthartige Druckausgleichspassage zwischen Brennraum und Kurbelraum ausgebildet ist. Dazu ist der brennraumzugewandte Kolbenring mit relativ großem Axialspiel in der entsprechenden Ringnut geführt. Die brennraumabgewandten Kolbenringe sind jeweils mit Ausnehmungen versehen, die den Ringraum zwischen benachbarten Kolbenringen mit dem Grund der jeweiligen Ringnut verbinden. In der brennraumfernen Ringnut ist darüber hinaus eine Bohrung vorgesehen, die den Grund der Ringnut mit dem Kolbeninnenraum verbindet. Damit wird ein Druckausgleich zwischen Brennraum und Kurbelraum ermöglicht.
