摘要： The present invention comprises a suspension spring and snubber arrangement for reducing transmitted noise from a reciprocating compressor at ⅓-octave frequency band of 500 Hz and preventing the occurrence of resonance frequency during the reciprocating compressor operation, the arrangement comprising: the suspension spring having a plurality of coils and two opposing open ends; at least one snubber for maintaining the integrity and shape of the suspension spring and for preventing displacement of the suspension spring from their intended position; wherein at least one open end of the suspension spring is loosely fitted over the at least one snubber; and further wherein an internal diameter of the suspension spring is larger than a outer diameter of the snubber so that a gap is defined between the suspension spring and the snubber for minimizing physical contact between the suspension spring and the snubber.

摘要： A crankshaft lubrication system is provided for generating increased oil pumping capacity and oil pressure in a sealed compressor for cooling fluids. The lower portion of an integral crankshaft is cut at a slanted angle to increase the inlet area for picking up more oil from a sump or oil reservoir. By varying the angle of cut at the lower portion of an integral crankshaft, one achieves oil pumping rates over a wide range of values while using a standard size crankshaft. This approach not only simplifies the manufacture of lubrication system for sealed compressors, but also lowers the overall production costs of such compressors. While the efficiency of sealed compressors is maintained under the present invention, the noise emissions from such compressors are lowered significantly.
摘要翻译：提供曲轴润滑系统，用于在用于冷却流体的密封压缩机中产生增加的抽油能力和油压。整体曲轴的下部以倾斜角度切割，以增加入口面积，以从油底壳或储油器拾取更多的油。通过改变整体曲轴下部的切割角度，可以在使用标准尺寸的曲轴时，在宽范围的数值范围内实现油泵送速率。这种方法不仅简化了密封压缩机的润滑系统的制造，而且降低了这种压缩机的总体生产成本。虽然本发明保持密封压缩机的效率，但是这种压缩机的噪声排放显着降低。

摘要： A compressor is having a tubular vertical shaft, which rotates about its vertical axis, a cylinder block for supporting the tubular vertical shaft, a rotor for driving the rotation of the tubular vertical shaft, and a stator affixed to the cylinder block. Lubricant is channelled from the lower end of the tubular vertical shaft through an inlet of its interior path to the outlet. A magnet is disposed within the interior path to trap ferrous contaminants in the lubricant before the lubricant is distributed to other parts of the compressor.
