摘要： Oil is subjected to at least one centrifugal separation to remove contaminants prior to its being supplied to the lubricating system. Additionally, there is at least a portion of the flow that is returned to the sump after separation without its being circulated for lubricating purposes. All of the contaminant collection areas are in a noncritical area in an area of continuous flow and located so as not to return contaminants to the oil sump.

摘要： Apparatus for modulating the capacity of a reciprocating compressor having a cylinder chamber and a valve assembly extending over the cylinder chamber, defining fluid inlet and outlet paths, and including a suction valve for regulating vapor flow through the inlet path. The capacity modulating apparatus comprises a lever, a fulcrum, and control means. The lever extends through the fluid inlet path and above the suction valve, and has a first end located outside the valve assembly and a second end engaging the suction valve. Both the fulcrum and the control means engage the lever, and the control means is provided for applying a variable force to the lever wherein the lever transmits the force to the suction valve to urge the suction valve to an open position.

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： A refrigeration system includes a plurality of compressors connected in series with each other. Each compressor has an oil sump located in a gravitational bottom of the compressor. A common supply line supplies refrigerant and oil to each of the plurality of compressors. The plurality of compressors includes a lead compressor and one or more non-lead compressors. The common supply line is configured to return more oil to the lead compressor than to the one or more non-lead compressors. Oil sump pressures for the plurality of compressors are maintained such that the lead compressor has the highest oil sump pressure, and the oil sump pressures of the non-lead compressors are successively lower with respect to its position downstream of the lead compressor. As a result, oil is distributed between adjacent compressors from the lead compressor, which is a most upstream compressor, sequentially downstream to the one or more non-lead compressors.

摘要： In addition to seating on its valve seat during the combined compression and discharge stroke, the suction valve seats on the structure associated with the valve seat which has at least one shallow recessed area. In seating on its valve seat, the suction valve seats on the structure defining the shallow recesses to trap fluid therein. The recesses serve to reduce the area available for adhesion and the trapped fluid pressure provides an opening bias to the suction valve. If necessary, or desired, restricted communication between the compression chamber and the shallow recess can take place to provide a higher pressure in the recess at the time of transition from discharge to suction.
摘要翻译：除了在组合的压缩和排出行程之内安装在其阀座上，吸入阀位于与具有至少一个浅凹陷区域的阀座相关联的结构上。在座阀座上，抽吸阀位于结构上，形成浅凹槽以在其中捕获流体。这些凹槽用于减小可用于粘合的面积，并且被捕获的流体压力为吸入阀提供打开偏压。如果需要或期望，可以发生压缩室和浅凹槽之间的有限连通，以在从排放到抽吸的过渡时在凹部中提供更高的压力。

摘要： Oil normally having refrigerant gas entrained therein is drawn from a sump. A portion of the oil is returned to the sump to agitate the oil in the sump to enhance gas separation therefrom. The remainder of the oil is subjected to centrifugal separation to remove the entrained refrigerant. The separated refrigerant is vented while the separated oil is fed to the lubrication system where contaminant removal takes place.
