Abstract: A pumping mechanism is disclosed. The pumping mechanism may include a barrel formed of a barrel substrate and including a first end surface, a second end surface opposite the first end surface, and a bore between the first and second end surfaces. Each of the first and second end surfaces and the bore is coated with a metal plating. The pumping mechanism may further include a plunger formed of a plunger substrate and configured to be slidably disposed in the bore in barrel, the plunger substrate having a tribological coating.

Abstract: The invention relates to a two-part piston (1) for an internal combustion engine, consisting of an upper part (2) and a lower part (3) which is screwed to the upper part. The upper part (2) and the lower part (3) are in contact with each other, partially by means of inner bearing surfaces (25, 26) defining the lower side of an upper ring rib (10) and the upper side of a lower ring rib (11), and partially by means of outer bearing surfaces (28, 29) defining the lower side of the ring wall (9) and the upper side of a collar (27) applied to the lower part (29). In order to avoid frictional rubbing, frictional heat sealing and pressure-related material heat sealing, at least one of the bearing surfaces (25, 26, 28, 29) is easily and economically provided with a chrome layer (30) which has a structured surface comprising a plurality of raised parts and recesses.

Abstract: Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.

Abstract translation: 虽然现代柴油燃料配方旨在减少柴油发动机的排放，但至少有些现代燃料往往具有较低的润滑性水平。 这里描述的控制阀组件有助于最小化否则通过提供阀元件，阀引导件和插入件而由使用这种低润滑性燃料而导致的任何增加的磨损。 阀元件容纳在阀引导件内并且能够在打开位置和关闭位置之间移动。 插入件与阀元件和阀引导件形成第一密封界面和第二密封界面。 当阀元件处于关闭位置时，第一密封界面和第二密封界面都被接合。 当阀元件处于打开位置时，第一密封界面和第二密封界面中只有一个接合。

Abstract: A rotary compressor includes: a compressing unit that includes an annular cylinder, an end plate, an annular piston which is fit in an eccentric portion of a rotation shaft, and a vane which protrudes from the inside of a vane groove of the cylinder to the inside of an operation chamber, comes into contact with the annular piston, and partitions the operation chamber into an inlet chamber and a compression chamber. The vane is formed of steel and has a diamond-like carbon layer formed on a sliding surface with respect to the annular piston. The annular piston is formed of Ni—Cr—Mo cast iron to which 0.15 wt % to 0.45 wt % of phosphorus is added, or is formed of cast iron or steel and has an iron nitride layer formed on an outer circumferential surface thereof.
