Abstract: An air filter element incudes a plurality of filter paper units each composed of a sheet of filter paper corrugated into a number of folds extending from one side to the other of the sheet, the filter paper units being arranged such that ridges of the folds extend on or parallel to radial lines extending radially outwardly from a center of the air cleaner element, and at least one connector interconnecting side edges of the filter paper units. With the air cleaner element incorporated in an air cleaner, air drawn into the air cleaner from an air inlet flows into a space above the air cleaner element, and then flows through the air cleaner element at a uniform speed over the entire area of the air cleaner element. Therefore, the air can uniformly be filtered, and the resistance to the air flow of the air cleaner element is reduced. The area of the air cleaner element which is open to the air flow is several times greater than the cross-sectional area of the air inlet. Since the speed of the air flow greatly drops upon entering the air inlet side of the air cleaner element from the air inlet, a chamber effect is produced.

Abstract: A filter medium forming system for forming a filter medium of the type wherein pleats radially outwardly extends in which sides of the pleats are alternately bonded at the inner and outer peripheral sides to allow fluid to be filtered flows generally along the length of the pleats. The filter medium forming system is comprised of a scoring device for forming linear depressions (score lines) on the opposite side surfaces of an elongate sheet-type filter medium. The scoring device is followed by an adhesive applying device for applying adhesive onto the opposite side surfaces of the filter medium at the edge sections. The adhesive applying device is followed by a pleating device for pleating the filter medium along the linear depressions to form a pleated filter medium having a plurality of pleats each having two sides contiguous through each linear depression. The pleating device is followed by a pressing device for tightly contacting the predetermined sections of the sides of each pleat to bond the predetermined sections with each other with the adhesive. Such a filter medium forming system is suitable for mass production for filter elements while making possible to form the flat filter medium into a predetermined pleated shape at high speed and with high accuracy.

Abstract: An improved return line filter is provided for use with a fluid system having a fluid reservoir which is at least partly filled with a fluid. The return line filter comprises an elongated housing having an open top and a partially open bottom and in which the housing is positioned within the reservoir so that the lower end of the housing is submerged in the reservoir fluid. A fluid inlet is formed on the lower end of the housing. A filter assembly is provided for use with the housing and comprises a tubular filter element open at each end and a holder assembly which is detachably secured to one axial end of the filter element. The entire filter assembly is insertable through the open top of the housing so that the tubular filter element is positioned coaxially around and spaced radially outwardly from a portion extending upwardly from the housing thus forming an annular chamber therebetween. Fluid seals sealingly connect both axial ends of the filter element with the housing portion while a fluid passageway fluidly connects the housing inlet with the annular inlet chamber. In addition, a deflection and antifoam tube secured to the holder assembly is positioned coaxially around and spaced radially outwardly from the filter element so that fluid flow from the filter element is deflected downwardly toward the partially open bottom of the housing. This construction for the filter assembly creates a reverse fluid flow in which the fluid must first flow upwardly from the bottom of the housing, out through the filter element and subsequently down through the lower open end of the housing.

The pleated and folded sheet is selectively disposed in flat panel form or formed into a tube with the pleats extending axially of the tube. When the filter is in its tubular form, the folded pleat ends are disposed at the exterior of the tube.

Abstract: A totally enclosed fuel oil filter housing having a fuel inlet nipple and a fuel outlet nipple is assembled on a mounting bracket with the nipples extending through hexagonal apertures in the mounting bracket. The inlet and outlet nipples are threaded to couple connecting fuel lines and are of different sizes to prevent a reversal of the connections. The nipples have hexagonal peripheries which mate the apertures so that torsional forces during coupling are transmitted to the bracket rather than to the seals between the nipples and the filter housing, and the apertures of the mounting bracket are formed by being drawn out of the plane of the base of the mounting bracket to project therefrom. The side walls of the housing has inwardly directed ribs and a bead of sealant spans each rib to localize the pressure between the side walls of the housing and the accordion pleated filter medium through the sealant bead to assure a void-free seal therebetween.
