Abstract: The invention relates to an end plate for filter material (10) for filtering a liquid, particularly a hydraulic oil, having a through opening (11) for filtered liquid, which is surrounded by a sealing ring (20) for a connecting piece, and a cover (12) for the filter material (10). The invention is characterized in that the sealing ring (20) delimits a free space (13) for accommodating an anti-rotation lock (14) of a switch (15) and/or a bypass valve (16) of a filter system (30). Furthermore, the invention relates to a filter element, a filter system and a method for filtering liquid.

Abstract: A liquid filter in the form of a filter element or a filter cartridge provides torsion locking relative to a filter head when the housing of such filter is threaded onto a filter head. Many embodiments employ a filter that includes a nipple portion at a top end with the torsion lock detent provided outboard of the nipple portion or integrated into the nipple portion. Many embodiments employ a simplified shoulder transition region at the top end of a torsion locked filter element. Valve actuation and/or filter differentiation is used in some embodiments. Different torsion locking arrangements, deformable thread profiles and other liquid filter features are disclosed.

Abstract: A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

Abstract: A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.

Abstract: A power unit including an internal combustion engine has an electric power generator mounted on an end of a crankshaft, a power transmitting member mounted on the other end of the crankshaft, and a lubricant oil filter. The oil filter partly overlaps the electric power generator as viewed in the direction of a crankshaft axis, and is positioned between the electric power generator and a crank weight on the crankshaft with respect to the direction of the crankshaft axis. The oil filter has a filter mount axis forming an acute angle to the crankshaft axis. The engine crankcase is thus prevented from bulging outwardly, and the power unit is reduced in size in its entirety.
