Abstract: The detonation-resistant material is applied to a piston to reduce the likelihood of damage to the piston 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 and around an annular portion of the crown adjacent the edge of the crown. The ring band is, before treatment, machined to form a recess 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 translation: 将防爆材料施加到活塞上以减少由粉碎或敲击引起的活塞损坏的可能性。 可以是镍或镍基材料的防爆材料被施加到环带的上部并且围绕邻近冠部边缘的冠部的环形部分。 环带在处理之前被加工成形成在其周围延伸的凹部，其通过电镀工艺填充有防爆材料。 因此，在环带上，防爆材料不会在环带的其余部分的径向向外延伸。 这降低了在相关联的气缸或衬套中的活塞运动期间防爆材料在相关联的气缸或衬套上刮擦或磨损的可能性，并且还降低了防爆材料被刮掉的可能性。

Abstract: A method is provided for designing and producing fiber-reinforced polymer (FRP) pistons. Pistons made with FRP have a lower mass than prior art metal pistons conferring advantageous engine efficiency and stability. FRP pistons also increase the thermal efficiency of engines by having a lower thermal conductivity, with tighter piston-to-bore clearance, and/increased air-fuel ratio than pistons of metal. The technical parameters of the piston are identified, and a piston body blank is produced. The blank is then machined, a bearing surface for the pin bore is created, the piston blank is optionally coated, is optionally subjected to Heavy Metal Ion Implantation (HMII) treatment and is subjected to sodium silicate impregnation to produce the final pistons.

Abstract: A scroll compressor is provided that may include a casing having a sealed inner space; a drive motor provided in the inner space of the casing to generate a rotational force; a rotational shaft rotatably coupled to the drive motor; an orbiting scroll formed of an aluminum material, and coupled to the rotational shaft to perform an orbiting movement; a fixed scroll coupled to the orbiting scroll to form a compression space; and an Oldham ring coupled to the orbiting scroll, and formed of a sintered metal. With this structure, it may be possible to prevent the Oldham ring from being worn out due to contact with the orbiting scroll. Further, a weight loss portion or wear-resistant coating layer may be formed on a portion of the Oldham ring, thereby suppressing or preventing vibration noise of the scroll compressor from being increased due to a weight increase of the Oldham ring.
