摘要： A scroll compressor with unfastened thrust plate includes a compressor housing and scroll compressor bodies disposed in the compressor housing. The scroll bodies include a fixed scroll body and a moveable scroll body. The fixed and moveable scroll bodies have respective bases and respective scroll ribs that project from the respective bases. The scroll ribs mutually engage. The moveable scroll body is movable relative to the fixed scroll body for compressing fluid. An upper bearing member provides axial thrust support to the moveable scroll compressor body through a bearing support via an unfastened thrust plate that is located between the upper bearing member and the moveable scroll body. The unfastened thrust plate has no means of attachment to the upper bearing member or to the moveable scroll body.

摘要： The drive connection between an eccentric pin and a slider block in a scroll compressor is angled such that any vertical force between the two will drive the slider block away from the orbiting scroll member. In this manner, manufacturing tolerances will not result in any drive connection which can have a net vertical force driving the slider block toward the orbiting scroll member.
摘要翻译：涡旋式压缩机中的偏心销和滑动块之间的驱动连接是成角度的，使得两者之间的任何垂直力将驱动滑块从远离涡旋构件的方向移动。以这种方式，制造公差不会导致任何驱动连接，其可以具有将滑动块朝向绕动涡旋构件驱动的净垂直力。

摘要： An abradable coating is formed on portions of the flank wall of the wraps of a scroll compressor. The radially outer portions of the flank wall are left uncoated, and can bear a force between the scroll wraps. In this manner, the load is not transferred through a coated portion, but rather through the uncoated portion. As the scroll wraps move relative to each other at run-in, the abradable coating wears away leaving a tight fit between the flank walls at the radially inner locations.

摘要： A method of operating a refrigeration system having at least three compressors, in which each compressor has an oil sump with oil at an oil level. The method includes separately connecting the oil sumps of the at least three compressors. Each separate connection allows oil flow only between the oil sumps of two of said compressors thereby preventing bypass flow. The method further includes flowing oil between oil sumps of the at least three compressors and along the separate connections to tend to equalize the oil levels among the oil sumps of the at least three compressors.

摘要： A scroll compressor is provided with a generally spiral wrap having an abradable or conformable coating on radially inner portions of its tip. The coating is not applied to radially outer portions. During operation of the scroll compressor, the coating will eliminate tip gap leakage adjacent radially inner, higher discharge pressure portions of the compression process. The outer, non-coated portions will bear the axial load, and ensure the coating will not wear away to an undue amount.

摘要： A refrigeration system with at least three compressors connected in a circuit. Each compressor has a housing with an oil sump. The oil sump is adapted to contain oil that defines an oil level. A supply line supplies refrigerant and entrained oil to each of the at least three compressors. The oil sump of each compressor has at least one oil port. Each oil port is disposed at an elevation that is equal to or minimally higher than the level of oil to promote equalization of oil levels in each compressor. There are a plurality of separate conduits which are not directly connected, but connected through the oil sumps of separate compressors. At least one compressor includes an oil sump extension having connections for the separate conduits. Each oil port is connected to the separate conduits or an oil sump extension. Each separate conduit connects a pair of compressors.

摘要： Scroll compressors are provided with vapor injection or by-pass ports that will allow greater flow of refrigerant through the port than was the case in the prior art. The prior art has typically utilized a single injection port having a diameter equal to or slightly larger than the thickness of the scroll wrap. In this way, the scroll wrap is able to prevent or restrict cross-flow leakage from the port from passing between the two compression chambers. However, this single port has also limited the amount of refrigerant that can be returned. In one embodiment, the present invention utilizes a plurality of ports generally spaced along the length of the wrap such that cross-flow can still be prevented while providing a greater cross-sectional flow area into or out of the compression chambers. In another embodiment, the several ports may be replaced by a single elongated port. Further, if cross-flow leakage is not a particular problem, the ports may be positioned such that they begin to communicate, and stop communicating, serially, with the two chambers.
摘要翻译：涡旋式压缩机配有蒸汽喷射或旁路端口，其将允许制冷剂通过端口的流量比现有技术中的情况更大。现有技术通常使用具有等于或略大于涡卷的厚度的直径的单个注射口。以这种方式，涡旋包裹体能够防止或限制来自端口的横流泄漏而不能在两个压缩室之间通过。然而，这个单一港口也限制了可以返还的制冷剂的数量。在一个实施例中，本发明利用沿着包装长度大致间隔开的多个端口，使得仍可以防止横流，同时向压缩室提供更大的横截面流动面积。在另一个实施例中，多个端口可以由单个细长端口代替。此外，如果交叉流泄漏不是特别的问题，则端口可以被定位成使得它们开始连通，并且与两个室连续地停止通信。

摘要： A scroll compressor having a hybrid wrap is defined to have its wrap origin offset from a drive center of both the orbiting and non-orbiting scroll members. The offset is selected in a direction such that it eliminates extremes in the torque curve relative to shaft rotation. In this way, torque reversal is generally eliminated.
