20140251895 | Filter, Filter Element, and Filter Housing - A fluid filter has a filter housing with a first filter housing part that has an installation opening for an exchangeable filter element and is closeable with a second filter housing part. The first filter housing part has a first sealing surface and the second filter housing part has a second sealing surface interacting with the first sealing surface. The filter element has a seal circumferentially and radially extending relative to a filter axis. The seal is arranged between the first and second sealing surfaces when the filter element is correctly installed. The seal has a positioning contour in which a course of the seal at least in one section has an axial directional component relative to the filter axis. The first and second sealing surfaces each have an appropriate positioning counter contour which receive the at least one positioning contour when the filter element is correctly installed. | 09-11-2014 |

20140130764 | CHARGE AIR DUCT FOR AN INTERNAL COMBUSTION ENGINE - A charge air duct for an internal combustion engine is provided that includes a housing having at least one inlet and at least one outlet for combustion air, and a heat exchanger, which is arranged in the housing and through which a fluid can flow, for cooling and/or heating the charge air. The housing is reinforced against pressure of the combustion air via a tie rod, wherein the tie rod is structurally integrated with the heat exchanger. | 05-15-2014 |
20130309585 | Ion Exchanger for Processing a Liquid Fluid - An ion exchanger for processing a liquid fluid of a functional system, in particular a cooling fluid of a cooling device, in particular of a fuel cell system is disclosed. The ion exchanger includes an ion exchanger tank ( | 11-21-2013 |
20090120046 | Hydrocarbon Adsorber with Purge Airflow Channel - An air cleaner assembly and an air induction system for an internal combustion engine. The air cleaner assembly preferably is formed using first and second housing members that are assembled to define an interior volume. A hydrocarbon adsorber is located within air induction system, e.g., within the interior volume of the air cleaner assembly. The hydrocarbon adsorber is positioned outside of the main air flow within a recess formed in a wall of one of the housing members. A purge channel is formed in the interior wall that houses the hydrocarbon adsorber. Air flow through the air induction system passes via the purge channel through the hydrocarbon adsorber. By facilitating air flow through the hydrocarbon adsorber that is positioned outside of the main airflow, the hydrocarbon adsorber is self-regenerating and does not have to be replaced over the lifetime of the vehicle as a result of hydrocarbon build-up. | 05-14-2009 |
20080271697 | Lower Intake Manifold with Charge Motion Control Valve - A lower intake manifold assembly includes a lower housing and a runner insert fitted into the lower housing. The lower housing may be made of metal and the runner insert may advantageously be made of a synthetic resin material. The runner insert provides a sealing surface between the lower housing and the cylinder head of an internal combustion engine. The runner insert also supports a charge motion control valve flap assembly that advantageously may include a shaft and synthetic resin flaps over-molded onto the shaft. | 11-06-2008 |
20080250772 | Multi-stage apparatus for separating liquid droplets from gases - Disclosed is a device for separating liquids from gases comprising a preseparator that separates an untreated gas region from a preseparator gas region, a main separator comprising a coalescing element for increasing the size of liquid droplets and a post-separator. | 10-16-2008 |
20080229722 | Filter Housing - The invention concerns a filter housing ( | 09-25-2008 |
20080223345 | Arrangement of a Charge Air Cooler in an Intake System of an Internal Combustion Engine - The arrangement of a charge air cooler in an intake system of an internal combustion engine has a charge air cooler that on the one hand is supplied with combustion air and on the other hand with a liquid coolant. A coolant/air cooler is provided in which the liquid coolant is cooled by an air stream. The charge air cooler is slantedly arranged in a pipe conduit for the charge air with regard to the end face of a heat exchanger block exposed to the charge air. The end face of the charge air cooler is arranged relative to the cross-section of the pipe conduit at an angle of >45°. | 09-18-2008 |
20080217235 | Liquid Filter - A liquid filter, in particular for the lubricating oil of an internal combustion engine, having a housing with an inlet and an outlet formed from a housing pot having a substantially downwardly open filter element installation opening and a screw-on cover that closes the installation opening, and a filter element arranged in the housing, sealingly separating the inlet from the outlet. The screw-on cover has a drain for residual liquid present in the housing with a round drain opening arranged in the central axis of the housing. A device for opening and closing the drain opening is arranged in the area of the drain and connected to an end disk of the filter element so that it moves relative to the drain opening and opens the drain when the cover is unscrewed. | 09-11-2008 |
