20080264850 | Filter Device, Especially for Filtering Liquids in Internal Combustion Engines - Disclosed is a filter device, especially for filtering liquids in internal combustion engines, comprising a filter element ( | 10-30-2008 |
20090127170 | Filter device, especially for filtering liquids in internal combustion engines - A filter device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A liquid to be filtered is introduced into the filter housing and flows through the filter element. An overflow valve is arranged between an entry side and a clean side of the filter element and has a valve body. The overflow valve is in an open position when a pressure of the liquid at the entry side of the filter element exceeds a threshold value. The valve body of the overflow valve is a sealing hose placed between the entry side and the clean side onto a cylindrical supporting body arranged in the filter housing. Flow openings are provided in the cylindrical supporting body. The sealing hose is arranged at the clean side of the supporting body. | 05-21-2009 |
20090301949 | Filtering System, in Particular for Filtering Liquids in Internal Combustion Engines - A filtering device for filtering liquids in internal combustion engines has a filter housing and a filter element inserted into the filter housing. A cover disk closes off the filter housing. The cover disk consists of two individual disks and a central flow connection connects the two individual disks. The two individual disks and the flow connection form a common plastic component. | 12-10-2009 |
20100224161 | Liquid Filtering Device - A filter arrangement for liquids has a filter housing and a functional carrier arranged inside the filter housing. A cylindrical filter element is inserted axially into the filter housing and defines an unfiltered side and a filtered side inside the filter housing. A non-return diaphragm is secured within the filter housing, wherein the non-return diaphragm is arranged on the functional carrier so as to effect an axial and/or radial sealing action of the unfiltered side relative to the filtered side of the filter arrangement. | 09-09-2010 |
20120012513 | Filter Element and Filter Module - A filter element of a filter system for filtering fluids has a filter medium with end faces. Terminal bodies, one each, are connected to one of the end faces of the filter medium, respectively. A support body extends between the terminal bodies. A first terminal body is connected by a toothed connection to the support body for transmitting a torque from the first terminal body onto the support body and from the support body onto the first terminal body. | 01-19-2012 |
20120279186 | Compact Filter, Method for Producing a Compact Filter, and Filter Medium - A compact filter has a compact filter element for exchangeable use in a filter housing and the compact filter element has a filter body of a web-shaped filter medium. The web-shaped filter medium has at least one flat filter medium web and one corrugated filter medium web that are placed onto each other and at least partially connected to each other by ultrasonic welding. At least one of the flat and corrugated filter medium webs is a composite filter medium web of at least two components, wherein at least one component is a synthetic material and one component is a non-synthetic material. The non-synthetic material is a plant-derived material and forms a support of the composite filter medium web and the synthetic material is a synthetic layer applied on the support. | 11-08-2012 |
20130098824 | Filter Device, in Particular Liquid Filter - A filter device has, in a housing, a filter element and, downstream of the filter element, an outflow opening for discharging the cleaned medium. Between the filter element and the outflow opening there is arranged a diverting part, wherein on the diverting part there is formed an overflow region for the flow of the medium from the filter element to the outflow opening, and the outflow opening is situated at the same level as or below the overflow region. | 04-25-2013 |
