    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: The invention relates to a chamber, in particular a pump chamber, comprising a plate-shaped first half (10) and a plate-shaped second half (12). The first and second halves are connected to one another by a closed connecting seam (20) in a surface-to-surface relation, and at least one half has at least one aperture (14) lying within the connecting seam. Furthermore, at least the second half is thermally deformed within the closed connecting seam in such a manner that it is formed to bulge relative to the connecting surface with the first half such that a hollow space (30) is formed between the first and second halves. In a second aspect, the invention relates to a pump having a configuration as described above. In a third aspect, the invention relates to a method for producing a chamber as described above.

    Abstract: An object is to provide a highly efficient compressor while improving a refrigerant leakage, enhancing a performance of a compressor, improving durability, and enhancing reliability. The compressor comprises: a compression element comprising a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid via the discharge port; a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber; and a shaft seal which is disposed on an end portion of the bearing (main bearing) on a side opposite to the compression member and which abuts on the rotary shaft.
