| 20090145882 | Protection Switch - A protection switch, particularly for rapid quenching of electrical arcing, includes at least one single-pole protection switch module having a housing, a movable contact mounted on a switching arm for pivoting against a fixed contact between a closed position and an open position and a quenching device for quenching electrical arcing of the switch. The quenching device includes a quenching chamber with an inlet and an outlet for the arc. A first running rail connects the fixed contact with a first side wall of the quenching chamber and a second running rail connects a stopping surface, against which the movable contact abuts in the open position of the switching arm, to a second side wall of the quenching chamber. A separation strip extends substantially from side wall to side wall at the outlet of the quenching chamber. | 06-11-2009 |
| 20090146766 | Protection Switch - A protection switch, particularly for fast switching, includes at least one single-pole protection switch module having a housing, a movable contact mounted on a switching arm for pivoting against a fixed contact between closed and open positions, a manual operating mechanism manually setting the switching arm between the closed and open positions, and a tripping mechanism automatically resetting the switching arm into the open position upon a tripping condition. The switching arm is spring-loaded in direction of the open position and includes a latch lever latching with the manual operating mechanism, and a contact lever carrying the moveable contact. The latch lever is pivotably mounted on the housing and joined to the contact lever by a hinge. The tripping mechanism includes a trip slider to be displaced by a trip device from a ready position towards a tripping position, to load the switching arm for rotationally fixing the contact lever. | 06-11-2009 |
| 20090160586 | Protection Switch - A protection switch includes a plurality of single-pole protection switch modules in a mechanically coherent unit forming a multi-pole protection switch configuration. Each module includes a housing, a switching arm, a moving contact on the switching arm pivotably movable against a fixed contact between closed and open positions, a manual operating mechanism for adjusting the switching arm between the closed and open positions and a tripping mechanism for automatically resetting the switching arm into the open position upon a tripping condition. The manual operating mechanisms of all modules are coupled so that the modules are only switched jointly. The tripping mechanisms of all modules are coupled so that the tripping mechanism of each also trips all others. A one-piece coupling is insertable between adjoining modules for both mechanically fixing the modules to one another and coupling the manual operating mechanisms and the tripping mechanisms of the adjoining protection switch modules. | 06-25-2009 |

| 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 |
| 20080308487 | Filtering device for liquids - A filtering device for filtering liquids features a pot-shaped filter housing for receiving a filter element contained therein, the filter housing being removably engaged with a connecting component (such a cover or a flange) by means of a bayonet connection. The bayonet connection includes a first positive-engaged element at the filter housing and a second positive-engaged element secured to the connecting component. The positive-engaged elements are to be brought into an axially positive locking position by axially shifting and rotating them around the housing's longitudinal axis. Furthermore, a blocking stage with a projection extending in axial direction is realized in one positive-engaged element; the allocated positive-engaged element abuts the projection in locking position, which allows also a positive locking position in circumferential direction. | 12-18-2008 |
| 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 |
| 20090159520 | Filter for an Internal Combustion Engine and Filter Cartridge for the Oil Filter - An oil filter for an internal combustion engine has a filter housing having an interior and an exchangeable filter cartridge arranged in the interior of the filter housing. A drainage valve is arranged in the filter housing and has a valve seat and a valve member. The valve member is movable relative to the valve seat in an opening direction that is parallel and coaxial to a longitudinal axis of the filter housing and oriented toward the interior of the filter housing. The valve member is received in the valve seat in a closing direction opposite to the opening direction. The valve member can be pushed out of the filter housing in the closing direction. The valve member and the filter cartridge form together a servicing unit for joint exchange of the valve member and the filter cartridge. | 06-25-2009 |
| 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 |
| 20120193281 | FILTER ELEMENT OF A LIQUID FILTER AND A LIQUID FILTER - A filter element for a liquid filter is arranged in the liquid filter housing that has at least two housing parts such that an inlet of the housing for liquid to be filtered is separated from an outlet of the housing for filtered liquid. The filter element has a filter medium provided with a terminal disk. The terminal disk has a seal support for an outer radial annular seal that is to be clamped in a clamping area between the housing parts that are separable from each other. The seal support of the filter element has axially at least a base member and a cover member. The base member is fixedly connected to the terminal disk. The cover member is attached to the terminal disk, to the base member, or to terminal disk and base member. The annular seal is positioned between base member and cover member. | 08-02-2012 |
