Patent WO-03027468-A1 (WO)
Inventor: BOSS JUERGEN
IPC: H01L41/04
Filed: 2002-07-13
Abstract: The invention concerns a fuel injection device comprising a fuel injection valve (12) having at least an injection valve element (34) for controlling at least an injection opening (36). Said injection valve element (34) is actuated against a closing force in the opening direction (35) by pressure exerted in the pressure chamber (44) of the fuel injection valve (12). Said pressure exerted in the pressure chamber (44) is produced by a plunger piston (18) of a high-pressure fuel pump (10), driven in a lifting movement by a cam (22). The inventive device further comprises a control valve (54) actuated by a piezoelectric actuator (58), and controlled by an electrical control unit (53) for controlling at least indirectly a connection (71) of the pressure chamber (44) with the balancing chamber. When the control valve (54) is closed, the pressure chamber (44) is separated from the balancing chamber, said control valve (54) including a control valve element (56) coupled with the actuator (58) via a fluid coupling (57). The actuator (58) is connected to a corresponding voltage measuring unit (72) after a turbocharging phase, the voltage between the electric terminals (61) of the actuator (58) being controlled in such a way as to detect the operating condition of the control valve (54).

Title: Luftmassendurchflussmesser mit kontrolierter strömungsablösungsposition
Inventor: PESAHL STEFAN
IPC: G01F1/684
Filed: 2002-08-16
Abstract: Wird bei Luftmassensensoren die Luftströmung in einem Kanal um ungefähr 90 DEG  umgelenkt, so kann es zu Strömungsablösungen kommen. Die ausserhalb des Ablöse/Rezirkulationsgebiet liegende Querschnittsfläche in dem Kanal wird verringert und die Strömungsgeschwindigkeit erhöht. Die Grösse und Lage der Rezirkulationsgebiete ist empfindlich gegenüber Störungen. Um definierte Strömungsbedingungen für eine Messeinrichtung zu erzielen, wird in dem Umlenkbereich ein Strömungselement vorgesehen, das in den Umlenkbereich vorsteht und eine Ablösung der Luftströmung von der Kanalinnenwand bewirkt.

Title: Safety cylinder lock with controlled actuating sequence - has catch element and regulator, uses second key
Inventor: MINGHSU SAM SHAIO
IPC: E05B27/00
Filed: 1973-08-23
Abstract: The lock consists of a housing with a cylinder which can rotate. There is a tumbler, controlling the cylinder movement; and a first key. A catch element works together with the cylinder and maintains it in a partly turned position. A regulator adjusts the catch element in a first, inactive, and a second, active position. The cylinder stops the first key from being withdrawn, when it is in the partly turned position. A second tumbler acts together with the regulator, and the cylinder. This tumbler may be actuated by a second key, to release the regulator. The key has indentations in it of various depths and the ends of the tumblers in the cylinder fit into these indentations, so that the cylinder can turn, as the junction between the tumbler elements in the cylinder and in the housing coincide with the circumference of the cylinder.

Title: Infinitely variable drive unit - has disc eccentrically adjustable at right angles to drive shaft
Inventor: DREIER KARL
IPC: F16H29/04
Filed: 1973-11-28
Abstract: The drive unit acts as a torque converter, its ratio being infinitely variable from nil upwards, and no support for the housing being required. A disc firmly secured to the driving shaft is adjustable eccentrically in a plane at 90 deg. to the shaft. The drive components rotate on an extension the disc in conjunction with segments guides for the pins so that their movement corresponds with those of the disc as this rotates eccentrically. The plungers have ramp faces bearing against the pin bearings at a variable angle to their tangential thrust axis. The increase of radius is relation to the pins occurring with every disc revolution is transmitted as a thrust via the links to the driven shaft, whereas the decrease on the opposite side causes pins with plungers to be moved tangentally inwards in guides.

Title: Transmission for fork lift truck - having both motors mounted on same side coupled to common gear box
Inventor: HANSEN RUDOLF
IPC: B60K1/02
Filed: 1974-01-30
Abstract: The fork lift truck has its two drive wheels driven by separate electric motors via reduction gearings. The reduction gearings ae mounted in a common housing for a simple layout while the two motors are mounted in a parallel setting on one side of the common housing. This enables repair work to be done on the motors simply by removing one drive wheel to gain access to both motors. The drive between the motors and the wheels is by means of different sized gear wheels to take account of the different relative positions of the motors from the axle.
