    Abstract: A method for operating an internal combustion engine, in whose exhaust gas system an exhaust gas treatment device is positioned, a reagent, which is possibly mixed with compressed air, being introduced into the exhaust gas system upstream from the exhaust gas treatment device, and a device for performing the method. The reagent is brought to a predefined reagent setpoint pressure using a reagent pump and subsequently metered using a reagent dosing valve. The reagent pressure existing upstream from the reagent dosing valve is detected. In the framework of a diagnosis, a time curve of the reagent setpoint pressure is predefined. The reagent pressure detected during the diagnosis is compared to at least one predefined threshold value. If the threshold value is exceeded, an error signal is provided. The corresponding diagnosis of a compressed air path may be provided alternatively or additionally to the diagnosis of the reagent path.

    Abstract: A pressure adjuster that has at least one valve, united with a valve block, with a valve dome that protrudes from the valve block. A cap includes a coil which is slipped over the valve dome. Electrical contact elements extend from both the coil and the cap and are joined together in a material bond. The electrical contact elements of the coil and of the cap are embodied resiliently. The electrical contact elements effect both the electrical connection and the mounting function for the coil. Moreover, the electrical contact elements allow aligning the coil as it is slipped onto the valve dome. The electrohydraulic pressure adjuster can be used in slip-controlled vehicle brake systems.

    Abstract: A pressure adjusting device that has at least one electromagnetically actuatable valve, which is united with a valve block and has both a valve dome that protrudes from the valve block and a coil that is alignable with and mountable on the valve dome. The coil is resiliently joined, by means of electrical contact elements to a cap that covers the coil and the valve dome and is fastened to the valve block. The mounted coil is also axially braced, remote from the valve block, on the cap with a spring element in the form of a sheet-metal spring, one side of the spring element engages the valve block and another side engages the coil. Jarring and impact strains on the electrical contact elements are thereby avoided. The electrohydraulic pressure adjusting device is usable for slip-controlled vehicle brake systems.
