Abstract: The invention relates to an oscillating motor adjuster having a driven stator, which is followed by a first rotor via a first hydraulic power transmission path, which is followed by a second rotor via a second hydraulic power transmission path. The second rotor is joined in a torsionally rigid manner to a second camshaft part, which is disposed coaxially to a first camshaft part, which is joined in a torsionally rigid manner to the first rotor. The relative angular position of the two rotors to one another can be adjusted very accurately by this sequential arrangement of the two rotors.

Abstract: An exhaust-gas aftertreatment device is provided, comprising a control unit for controlling a diaphragm pump that draws a urea/water solution out of a circuit and pumps it, via a pressure filter, to a metering unit comprising an atomizing nozzle for atomizing the urea/water solution into an exhaust-gas stream. The metering unit may also comprise a metering valve, including an atomizing nozzle, a pressure and temperature sensor, a heating means and a return baffle.

Abstract: The invention relates to a solenoid valve that is to be mounted leaktight and in a simple manner. Provided according to the invention is a first housing part with a tool engagement portion for screwing of a second housing part into an inner thread of a receptacle. The two housing parts are joined immovably to each other. The first housing part has a tensile strength that is greater than a tensile strength of second housing part.
Abstract: The invention relates to a hydraulic valve for an oscillating motor adjuster that utilizes camshaft alternating torques by means of non-return valves for more rapid adjustment. The non-return valve that is not used for the respective rotation is additionally closed by means of the piston of the hydraulic valve.
Abstract: The invention relates to an exhaust-gas aftertreatment device, comprising a control unit (4) for controlling a diaphragm pump (2) that draws a urea/water solution out of a circuit and pumps it, via a pressure filter (3), to a metering unit comprising an atomizing nozzle for atomizing the urea/water solution into an exhaust-gas stream. In advantageous developments, the metering unit comprises a metering valve, including an atomizing nozzle, a pressure and temperature sensor, a heating means and a return baffle.

Abstract: The present invention provides a cam shaft adjuster, which is designed for controlling a double cam shaft, which has a layered construction. The cam shaft adjuster is equipped with a first rotor-type output body and a second rotor-type output body which are arranged parallel to each other with their rotary vane body parts.
Abstract: An SCR exhaust gas aftertreatment device in which a urea-water solution is injected into an exhaust gas line is provided. At least one component of the device (e.g., a filter element) lies in an area of an internal space, and is bounded by an elastomer membrane that is embedded in a frost equalization foam. This prevents freezing damage even over a very long period of time and a large number of freezing cycles.
