  • Patent number: 7859141
    Abstract: The invention relates to an electrical machine of the transversal-flux type. The machine comprises a stator and a movable element. The stator has a plurality of stator elements with magnetic flux conductors and an electric winding extending in a closed winding path through each magnetic flux conductor. The movable element comprises a number of permanent-magnet members and is movable in relation to the stator along a movement path. The winding path comprises a first current-carrying section extending along the movement path. Each magnetic flux conductor forms, together with one of the permanent-magnet members, a closed magnetic flux circuit around said current-carrying section. Each permanent-magnet member comprises a primary magnet with a magnetic direction across the movement path.

  • Patent number: 6978769
    Abstract: A method of controlling the fuel injection to a combustion chamber (4), comprises the steps of: supplying fuel to a pump (2), which has a piston (7) reciprocating in the a cylinder (6), pressurizing the fuel by applying a force onto the piston (7) by an actuator (8), so that the piston (7) is displaced from a first end position (9) towards a second end position (10), injection of fuel corresponding to a partial volume of the fuel pressurized in the cylinder (6), into the combustion chamber (4), and returning the piston (7) towards the first end position (9) by the pressurized fuel, so that the piston (7) acts with a driving force on the actuator (8). The invention also relates to a fuel injection device for carrying out the method.
