20090060716 | Compressor Casing for an Exhaust Gas Turbocharger - A compressor casing for an exhaust gas turbocharger is disclosed. The exhaust gas turbocharger has a rotatable turboshaft, a compressor wheel mounted on the turboshaft, and a turbine wheel mounted on the turboshaft. The compressor casing includes a sensor for measuring a rotational speed of the turboshaft. The sensor is embedded in the compressor casing and forms an integral component of the compressor casing. | 03-05-2009 |
20090126498 | Pressure sensor device - The invention relates to a pressure sensor device comprising a membrane body in the form of a membrane whose first side is exposed to a working medium whereas the second side thereof is arranged oppositely to the first side. The inventive device also comprises at least one pressure sensor element ( | 05-21-2009 |
20100026284 | Element for Generating a Magnetic Field - An element for generating a magnetic field, having an annular frame for receiving an annular magnet which rotates with a turboshaft. The magnet is mounted in the frame such that the frame stabilizes and guides the magnet mechanically. In order to specify an element for generating a magnetic field which reliably fixes and guides the magnet, the magnet is connected to the frame by at least one spot weld. | 02-04-2010 |
20100175375 | Waste gate actuator for an exhaust gas turbocharger - A waste gate actuator for an exhaust gas turbocharger, including an actuator housing and an actuator cover, an element for actuating the waste gate valve and electronic components for controlling the element to actuate the waste gate valve being arranged in the waste gate actuator. Provided is a simple and inexpensive revolution counting system on the turbocharger which allows the number of revolutions of the rotating parts (turbine wheel, compressor wheel, turboshaft to be detected without substantial constructional alterations to the design of existing turbochargers. A sensor for detecting the variations in a magnetic field that are produced by the rotation of the rotating parts is arranged in or on the actuator housing or in or on the actuator cover. | 07-15-2010 |
20100307230 | METHOD AND SYSTEM FOR MONITORING THE STATE OF AN ENGINE OIL IN AN INTERNAL COMBUSTION ENGINE - A method for monitoring the state or an engine oil in an internal combustion engine, in which first the viscosity of the engine oil is determined at different temperatures of the engine oil, after which a viscosity index is ascertained from the viscosity and the temperature of the engine oil, which method permits a reliable statement about the state of the engine oil during its issue in the internal combustion engine to be made, the viscosity index of the engine oil is determined at different successive times and the change of the viscosity index over time is used as a measure for assessing the oil state. | 12-09-2010 |
20100308836 | MONITORING CIRCUIT FOR AN ENERGY STORE AND METHOD FOR MONITORING AN ENERGY STORE - A monitoring circuit is provided for an energy storage device. The energy storage device has a plurality of cells which each provide a voltage between their first and second connections and are switched in series. At least two voltage measuring circuits are provided, wherein the voltage measuring circuits each measure the voltage between a first measurement input and a second measurement input. A first connection conductor connects the first terminal of the first cell to the first measurement input of a first voltage measurement circuit. A second connection conductor connects the second terminal of the first cell to the second measurement input of a first voltage measurement circuit. A first load resistor can be switched between the first measurement input of the second voltage measurement circuit and a first fixed potential. | 12-09-2010 |
