    Abstract: A refrigerant compressor includes a compression unit having a roller and a vane for compressing refrigerant. The vane has a film having first to fourth layers on its metallic base member. The first layer is made of chromium. The second layer is made of chromium and tungsten-carbide. The third layer is made of metal-containing amorphous-carbon containing at least tungsten or tungsten-carbide. The fourth layer is made of non-metal-containing amorphous-carbon containing carbon and hydrogen. In the second layer, chromium content-rate on a first-layer side is larger than on a third-layer side, and tungsten-carbide content-rate on the third-layer side is larger than on the first-layer side. In the third layer, content-rate of the at least tungsten or tungsten-carbide on a second-layer side is larger than on a fourth-layer side. The roller with which an end-edge of the vane slidably-contacts is made of flake graphite cast iron containing molybdenum, nickel and chromium.

    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: 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.
