20080231399 | Electromagnetic device with displaceable connections - An electromagnetic switching device for controlling a branch includes, in at least one embodiment, a housing with a length in a longitudinal direction, with a first end side, which is oriented at right angles with respect to the longitudinal direction, and with a second end side, which is opposite the first end side and is oriented at right angles with respect to the longitudinal direction; a control coil, which is arranged in the housing, for actuating an electrical switch with a first and second coil contact; and a first and second connection element, which are arranged partially in the housing. In at least one embodiment, the connection elements are capable of being displaced in the longitudinal direction relative to the housing between a first and a second end position in such a way that they are freely accessible on one of the end sides in the first end position, are freely accessible on the other of the end sides in a second end position, and are electrically connected to the associated coil contacts both in the first end position and in the second end position. | 09-25-2008 |
20090325423 | Adapter for a main current path tap of a switching device - At least one embodiment of the invention relates to an adapter for producing an electrically conductive connection between at least one main current path of a switching device and an evaluation unit for determining the state of a protective apparatus, which is connected upstream of the switching device. In order to make it possible to monitor a protective apparatus which is connected upstream of the switching device with minimum wiring complexity, at least one embodiment of the invention proposes an adapter for producing an electrically conductive connection between at least one main current path of a switching device and an evaluation unit for determining the state of a protective apparatus which is connected upstream of the switching device, wherein the adapter can be connected mechanically to the switching device and has contact interfaces for connection of the evaluation unit. As a result of the direct evaluation of the switching state of the protective organ on the switching device, the wiring which until now has been necessary for an additional auxiliary switch on the protective device is dispensed with, a possible fault source also being minimized with the wiring complexity. | 12-31-2009 |
20100127805 | PRODUCTION METHOD FOR AN ELECTROMAGNETIC SWITCHING DEVICE HAVING PARTITION WALLS BETWEEN PRIMARY AND AUXILIARY CONTACTS AND AN ELECTROMAGNETIC SWITCHING DEVICE PRODUCED ACCORDING TO THE PRODUCTION METHOD - In one embodiment of the present invention, a production method for an electromagnetic switching device includes the following steps in the sequence listed: producing a one-piece switching chamber, producing a contact bridge carrier and equipping the contact bridge carrier with movable contact bridges, wherein the contact bridges include a plurality of primary contact bridges and at least one auxiliary contact bridge; inserting the contact bridge carrier equipped with the movable contact bridges into the switching chamber; inserting partition elements into the switching chamber so that each partition element is arranged between a bridge contact point of one of the primary contact bridges and a bridge contact point of one of the auxiliary contact bridges, and equipping the switching chamber with fixed primary counter-contact points; fixing primary covers to the switching chamber so that the primary covers cover the primary counter-contact points and fix the partition elements in the switching chamber. | 05-27-2010 |

20110106409 | METHOD AND DEVICE FOR THE PRESSURE WAVE COMPENSATION DURING CONSECUTIVE INJECTIONS IN AN INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE - A method and a device for controlling an injection system of an internal combustion engine are described, in which at least two consecutive partial injections are compensated for using pressure wave compensation, it is provided in particular that two test injections having a specified time interval to one another are triggered in a cylinder of the internal combustion engine, the total injection quantity of the at least two partial injections is ascertained, and a deviation between the ascertained total injection quantity and an expected total injection quantity is assumed as the error of the pressure wave compensation and a correction value for the pressure wave compensation is determined therefrom. | 05-05-2011 |
20150034048 | METHOD AND DEVICE FOR ZERO-FUEL QUANTITY CALIBRATION OF A FUEL INJECTOR - In a method for calibrating a fuel metering system including an injector of an internal combustion engine performing a pilot injection chronologically prior to a main injection, at least two test injections chronologically prior to the pilot injection are provided for the injector, the first test injection being carried out using a first activation duration, in which the injector does not yet open, at least one second test injection being carried out in a subsequent injection cycle using an activation duration which is progressively increased in each case in relation to the first test injection until a change of an operating variable of the fuel metering system or the internal combustion engine results, which activation duration corresponds to a minimum activation duration of the injector. | 02-05-2015 |
20150053179 | METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE - A method for controlling an internal combustion engine includes: using the pressure sensor method, determining for a first injector a first control period during which a desired quantity of fuel is injected into a lead cylinder; controlling the first injector with the first control period and entering a quantity replacement signal resulting therefrom into a training characteristic field as a function of the drive train parameters; and using null quantity calibration, varying for all further cylinders a control period of the injectors assigned to the cylinders until the quantity replacement signal is reached. | 02-26-2015 |
