Abstract: A fluid filter assembly comprises a heater and a filter in series fluid flow relationship. A means for bypassing a fluid around the heater and the filter is provided which comprises ducts and a relief valve interposed between them. In normal operation the relief valve is closed so all the fluid flows through the heater and the filter. The fluid and any liquid impurities entrained therein are heated by the heater prior to passing through the filter. At low temperatures the heater cannot normally provide sufficient heat to prevent solidification of the liquid impurities entrained within the fluid which block the filter. The relief valve then opens to allow a proportion of fluid to flow through the bypass so a reduced amount of fluid flows through the heater and the filter. The heater heats the reduced flow of fluid therethrough to a temperature sufficiently high to melt the solidified liquid impurities blocking the filter.

Abstract: A friction-reducing lubricating-oil filter for Internal Combustion Engine and in which a solid-lubricant-feeding equipment is equipped on the lubricating-oil duct where the lubricating-oil has been finely cleaned and has not got to the friction parts, which is wholly sealed and is filled with solid lubricant, on which there are several holes evenly arranged; when the lubricating-oil flows over the outside surface of said solid-lubricant-feeding equipment and said holes, because the static pressure of the flowing liquid is lower, the solid lubricant in the solid-lubricant-feeding equipment is drawn out through said holes and mixes with the lubricating-oil. This friction-reducing lubricating-oil equipment doesn't need any other driving equipment and can transfer the solid lubricant to the friction parts without filtering out by the filter, and therefore is not only simple in structure, but also very effective in friction-reducing.

Abstract: An oil pump of an internal-combustion engine supplies dirty oil through a vertically extending oil feeding duct into a ring duct of an oil filter flange. From there, the oil flows through the oil filter and a central bore into a main oil duct. Since the oil feeding duct leads into the ring duct above the central bore, and the main oil duct extends above the central bore, the filter oil level, will not fall under the level of the dirty-oil inlet into the ring duct when the engine is switched off. A complete emptying of the oil filter is therefore prevented when the engine is switched off, and a fast oil pressure buildup is promoted when the engine is started again.
