| 20090211362 | PRESSURE SENSOR - A pressure sensor is provided with a carrier ( | 08-27-2009 |
| 20090127961 | PERMANENT MAGNET ROTOR - The invention relates to a permanent magnet rotor for an electric motor, in which the permanent magnets inside the rotor extend parallel to the rotation axis of the rotor, and in the area of the radially outer longitudinal edges of the permanent magnets, grooves that are open to the outside are formed on the outer periphery of the rotor. These groves are each, in a peripheral direction, slanted or curved with regard to the longitudinal edge of the adjacent permanent magnets. The center line of each groove intersects the longitudinal edge of the adjacent permanent magnet at least once. The grooves on the outside of the rotor have, in the peripheral direction, a smaller width than in an area of the groove situated radially further inside, and the cross-sectional shape of the groove is constant over the length of the rotor. The invention also relates to a method for producing a rotor of the aforementioned type. | 05-21-2009 |
| 20090038292 | Dosing Pump Assembly - A metering pump assembly for admixing a fluid reduction agent from a supply container and a pressurized air flow into an exhaust gas flow of a combustion engine includes an assembly housing and a pre-mixer at least partially within the housing. A membrane pump within the housing is fluidly connected between the supply container and the pre-mixer. An electric motor generates a rotational output. A transmission converts the rotational output of the electric motor into translatory movement. The translatory movement drives the membrane pump to pump the reduction agent from the supply container into the pre-mixer. The pressurized air flow is in fluid communication with the pre-mixer and mixes with the reduction agent within the pre-mixer to form a reduction agent air mixture. An exit conduit fluidly connects the pre-mixer to the exhaust gas flow. The reduction air mixture is delivered through the exit conduit and into the exhaust gas flow. | 02-12-2009 |
