摘要： PCT No. PCT/GB97/00179 Sec. 371 Date Sep. 22, 1998 Sec. 102(e) Date Sep. 22, 1998 PCT Filed Jan. 21, 1997 PCT Pub. No. WO97/26978 PCT Pub. Date Jul. 31, 1997An oil reclamation device includes a full flow filter (10) fitted around a partial flow filter (12) within an open-ended casing (8). The open end of the casing is capped by a housing defining a vaporization chamber (6). In normal operation, oil flows from oil passage (14) through the full flow filter (10) to a branched leg (22). A metering jet (34) provided in the branched leg allows a minor portion of the oil to flow through the partial flow filter and then into the vaporization chamber. The full flow filter extracts solid contaminants having a particle size of 15 microns or greater. The partial flow filter extracts solid contaminants of 1 micron or greater. The filter element of the partial flow filter is composed of compressed cotton fibers and preferably has a higher density in an upper end adjacent the vaporization chamber. In the vaporization chamber, liquid contaminants are removed from the minor portion by a heating element (72). The temperature within the chamber is monitored and controlled by a thermocouple (74) and an indicating device is also provided to warn an operator when the temperature is not within an acceptable range. The oil passage includes a bypass valve (28) so that oil can bypass the full flow filter when it is clogged. An audible or visual indicating means is provided to warn an operator when the bypass valve is opened.
