摘要： A scroll compressor has a pair of mating scrolls that are disposed on parallel, eccentric axes, and each of these scrolls has a scroll plate and a spiral, involute wrap. The scrolls are driven so that one of them orbits about the axis of the other scroll while maintaining a fixed azimuthal relationship to it. The orbital motion causes a compressible fluid to enter at the periphery of the scrolls, and be carried and compressed by pockets formed between the mating wraps of these scrolls. The compressed gas is discharged out a discharge port at the center of one of the scrolls. The discharge port is bored diagonally into the scroll plate of the one scroll so that it has an elongated elliptical aperture at the center of the scroll plate. The port is machined into the scroll from the wrap side of the scroll. The enlarged size of the port aperture reduces the resistance to fluid flow and hence reduces the back pressure, thereby increasing the compressor efficiency.

摘要： Axial compliancy is achieved in a scroll compressor by providing a fluid pressure bias to the back of the orbiting scroll. The fluid pressure bias is supplied by one or more pockets configured to combine the efficient use of the available area with ease of manufacture.

摘要： The crankshaft and orbiting scroll of a scroll compressor are drivingly connected through a bearing. The bearing is made up of a plurality of roller elements of varying diameters in line contact with both the crankshaft and the orbiting scroll and serving to locate the crankshaft and orbiting scroll eccentrically with respect to each other and thereby provide radial compliancy.

摘要： Leakage in a scroll wrap compressor is reduced by providing a roughened scroll wrap tip surface at the gap between the tip and the cooperating base so as to increase the frictional resistance to flow of fluid through the gap and to cause turbulence within the gap to further increase the resistance to the flow of fluid from the high pressure to the low pressure side across a scroll wrap tip. Various types of surfaces are shown for increasing the frictional resistance to flow such as knurling, grooving, cast cavities, metal particles and fibers and the like.

摘要： The scroll elements of a scroll-type compressor are treated employing a lapping tool to achieve increased flatness of the base surface and increased smoothness of the side walls of the involute wrap. This reduces flank leakage, tip leakage, and thrust friction losses. The lapping device that is placed against the scroll element has a radially extending base and a generally spiral wrap, the wrap generally matching that of the scroll element workpiece. The lapping device wrap has axially erect walls and a radially flat tip surface. After engaging the scroll element work piece, the lapping device is moved relative to the scroll element in an orbiting motion. A suitable lapping compound is introduced at least between the lapping device wrap tip surface and the base surface of the scroll element, and, if desired, also between the side walls of the lapping device wrap and the side walls of the scroll element wrap. The lapping compound can be introduced directly or in a gas flow.

摘要： The orientation of the elements of a slider block radial compliance mechanism for a scroll compressor is such that the point of application of the actuating force is shifted from a first line extending through the center of gravity of the counterweight and the axis of the crankshaft to a second line parallel to said first line and extending through the axis of the orbiting scroll. The result of the changed orientation is an increase in the magnitude of both the sealing force between the scroll elements and the actuating force to move the mechanism.

摘要： A method is provided for achieving low NOx in the operation of a non-premixed combustion system by reacting a fuel-rich mixture to produce partial reaction products plus heat, transferring a portion of the heat to a bypass air stream, and passing the cooled partial reaction products into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream. A supply of fuel and a supply of air is provided; and a fuel-rich mixture is formed and reacted to produce partial reaction products plus a heat of reaction. A portion of the heat of reaction is transferred to a bypass air stream and the cooled partial reaction products are passed into non-premixed contact and combustion with a stoichiometric portion of the heated bypass air stream.

摘要： A scroll compressor can be provided with different wrap thicknesses to compensate for the different material properties of the orbiting and fixed scroll elements. The concept of different wrap thicknesses also aids in the select-fitting of parts and in the provision of and adjustment of a clearance or spacing between the wrap elements. Additionally, in the manufacture of a scroll compressor, the total wrap thickness of the two wraps is kept constant within narrow tolerances while the individual wrap thicknesses are allowed to vary over a predetermined range. The cutting tools used are sized such that even if they differ in their cutting diameters, the combined cutting diameters, and therefore the total wrap thicknesses, are constant within narrow tolerances. This permits the tools to be used and resharpened until their cutting diameters fall below the minimum acceptable diameter.
摘要翻译：涡旋压缩机可以设置有不同的包裹厚度，以补偿轨道和固定涡旋件的不同材料特性。不同包裹厚度的概念还有助于部件的选择配合，以及提供和调节包裹元件之间的间隙或间隔。此外，在涡旋压缩机的制造中，两个包装的总包裹厚度在窄公差范围内保持恒定，同时允许单个包装厚度在预定范围内变化。所使用的切削工具的尺寸使得即使它们的切割直径不同，组合的切割直径也因此总包裹厚度在窄公差范围内是恒定的。这允许使用工具并重新硬化直到它们的切割直径低于最小可接受的直径。
