  • Patent number: 10371197
    Abstract: A foil segment bearing comprises a bearing backing with a through opening. A shaft is arranged in the through opening such that a gap exists between the shaft and the bearing backing. The foil segment bearing also has at least one first bearing segment and one second bearing segment with respective inner surfaces. Each of the respective inner surfaces defines a bearing surface with an adjustable circumference. The bearing segments are arranged in the bearing backing at a distance from the shaft such that a gap exists between the shaft and the bearing segments. The foil segment bearing also has a foil arrangement arranged in the gap between the inner surfaces of the bearing segments and the shaft. The foil segment bearing also has an adjustment mechanism configured to set a geometry of the gap.

  • Patent number: 9279400
    Abstract: The invention relates to an injection device (1), designed in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve needle (14), an injection chamber (12) having at least one injection opening (44), and a control chamber (20). The injection device (1) is designed such that a pressure differential between the injection chamber (12) and the control chamber (20) brings about a displacement of the valve needle (14) between an open position in which a fluid flow through the injection opening (44) from the injection chamber (12) is released, and a closed position, in which the injection opening (44) is closed off.

  • Patent number: 9206779
    Abstract: The invention relates to an injection device, in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve unit which comprises a valve needle, an injection chamber having at least one injection opening, and a control chamber, wherein the injection device is designed so that a pressure differential between the injection chamber and the control chamber brings about a displacement of the valve needle between an open position in which the valve needle releases a fluid flow through the injection opening, and a closed position in which the valve needle closes off the injection opening. The injection device also has a pump unit integrated in the injection device. The pump unit is designed so as to draw in fluid from the fluid inlet during operation and to provide said fluid to the valve unit under increased pressure.

  • Publication number: 20130119161
    Abstract: The invention relates to an injection device (2), in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve unit which comprises a valve needle (6), an injection chamber (38) having at least one injection opening (8), and a control chamber (36), wherein the injection device (2) is designed so that a pressure differential between the injection chamber (38) and the control chamber (36) brings about a displacement of the valve needle (6) between an open position in which the valve needle (6) releases a fluid flow (through the injection opening (8), and a closed position in which the valve needle (6) closes off the injection opening (8). The injection device (2) also has a pump unit integrated in the injection device (2). The pump unit is designed so as to draw in fluid from the fluid inlet (32) during operation and to provide said fluid to the valve unit under increased pressure.
