  • Patent number: 5656156
    Abstract: A solvent parts washer of the closed cycle type has an additional, independently controlled continuously cycled pump which recycles the solvent through a bypass filter. The pump has a suction inlet at the bottom of the parts washer bin and continuously passes a flow of solvent through the pass filter. This is one of a number of filters, commonly known as paper towel or paper roll filters, in which a liquid to be filtered is forced at a high pressure and low flow rate along the interstices between adjacent compacted sheets of a filtering medium. Such filter media and filters have relatively low flow rates because of their cleaning (filtering) capability is by absorption rather than screening, but have an exceptionally high ability to remove particles down to the sub-micron level from a filtered liquid. An agitator pipe in the solvent return flow serves to flush particulate contamination into the filter pump inlet. The invention maintains the solvent substantially free of contamination above the 0.

  • Patent number: 5566781
    Abstract: Apparatus and methods for flushing and cleaning the oil strainer and crankcase of an internal combustion engine of a type having a removable full-flow oil filter. The oil filter is temporarily replaced with a cartridge which has at least one passage therethrough which will communicate with the discharge side of the engine oil pump but does not communicate with the normal outflow port of the filter apparatus. A second passage therethrough may communicate with the outflow port of the filter system but does not communicate with the discharge of the oil pump. In a preferred method, the inlet of the first passage may be connected to a source of pressurized fluid to force the fluid, in a direction opposite to normal flow, through the passage, the oil pump and the oil strainer to agitate and flush contaminants in the oil strainer and crankcase. The pressurized fluid and contaminants are drained from the crankcase after which the cartridge is removed, a new oil filter installed and clean oil added to the engine.
