    Abstract: The detonation-resistant material is applied to a piston (10) caused by pinking or knocking. The detonation-resistant material, which may be nickel or a nickel based material, is applied to the upper part of the ring band (12) and around an annular portion (19) of the crown adjacent the edge (13) of the crown. The ring band is, before treatment, machined to form a recess (15) extending therearound which is filled with the detonation-resistant material by a plating process. Thus, on the ring band, the detonation-resistant material does not extend radially outwardly of the remainder of the ring band. This reduces the possibility of the detonation-resistant material scraping or scuffing on the associated cylinder or liner during movement of the piston in the associated cylinder or liner and also reduces the likelihood of the detonation-resistant material being scraped off.

    Abstract: A piston for a diesel internal combustion engine including a crown portion at least partially formed of steel and having a combustion surface with a combustion bowl formed therein is provided. The combustion bowl presents a combustion bowl rim area, and a coating including at least one of a noble metal and a refractory metal is applied to substantially only the combustion bowl rim area. The coating is preferably applied in the areas of the combustion bowl rim area that are in line with the sprays of diesel fuel when the piston is in a top dead center position during operation of the engine.

    Abstract translation: 一种柴油机内燃机的活塞，其特征在于，具备至少部分由钢制成的具有形成有燃烧碗的燃烧面的冠部的冠部。 燃烧碗具有燃烧碗边缘区域，并且包括贵金属和难熔金属中的至少一种的涂层基本上被施加到燃烧碗边缘区域。 当在发动机操作期间活塞处于上止点位置时，该涂层优选地应用于燃烧碗形边缘区域与柴油燃料喷雾一致的区域中。

    Abstract: Gegenstand der Erfindung ist eine hydraulische Zahnradmaschine, vorzugsweise Zahnradpumpe, mit mindestens zwei ineinander greifenden, drehbar gelagerten Zahnrädern (3, 4). Zwischen mindestens einer Zahnradstirnseite und einem nicht drehenden Bauteil (8) der Zahnradmaschine ist eine scheibenförmige Dichtplatte (9) angeordnet. Erfindungsgemäß ist in der Dichtplatte (9) und/oder in dem nicht drehenden Bauteil (8) mindestens eine Kerbe (10) zur hydrostatischen Druckbeaufschlagung vorgesehen ist. Bevorzugt ist die Kerbe (10) in dem nicht drehenden Bauteil (8) vorgesehen. Zumindest die der Zahnradstirnseite zugewandte Seite der Dichtplatte (9) ist von einer Bronzelegierung gebildet.
