| 122 | Refrigeration chiller with assured start-up lubricant supply | US263389 | 1999-03-05 | US6116046A | 2000-09-12 | Daniel C. Leaver; Sean A. Smith |
| An assured supply of lubricant to the compressor in a refrigeration chiller is provided by a reservoir that is connected in parallel with the main line by which lubricant is supplied to the compressor. The reservoir is connected to the main lubricant supply line in a manner such that if the lubricant supply line is blown dry, as can occur as a result of an unusual or abnormal chiller shutdown condition, a critical portion of the supply line will be refilled by the reservoir relatively very quickly which assures the immediate availability of lubricant to the compressor from that portion of the lubricant supply line when it next starts up. | ||||||

| 138 | Liquid cooled compressor with improved liquid separation | US189815 | 1980-09-23 | US4420293A | 1983-12-13 | Rudolf Hofmann |
| A screw compressor with liquid injection wherein the units previously disposed separately from one another, such as the air filter, liquid separator, and so on, are integrated into a single housing. Various compartments are formed in the housing by means of partitions, such that the compartments provide for good separation of entrained liquid from the compressed air being achieved because of large flow cross-section, maximum utilization of the available flowpath and multiple deflection of the current of compressed air. The compact construction results in a substantially smaller overall compressor size than that of comparable known compressor plants, in a reduction of manufacturing cost and simplification of the assembly of a compressor plant. | ||||||
