  • Patent number: 9909537
    Abstract: A gas injector, for injecting gaseous fuel, includes a valve body having a first valve seat and a second valve seat, and a closing element, which has a first sealing region, a second sealing region, a hollow region, which is delimited by a bottom and a wall, and an outlet opening configured in the bottom, the first valve seat sealing at the first sealing region, and the second valve seat sealing at the second sealing region, and at least one through opening being provided in the wall of the closing element, so that the gaseous fuel is able to be expelled both from the inner hollow region and the outer region of the closing element.

  • Patent number: 9810179
    Abstract: A gas injector for the direct injection of gaseous fuel into a combustion chamber of an internal combustion engine, including a valve seat, a valve needle, which in response to a lift releases a first cross-sectional area at the valve seat, and a gas control region, which is situated at the valve needle and defines a second cross-sectional area together with a component surrounding the valve needle, and in response to a lift, a change in the first cross-sectional area at the valve seat differs from a change in the second cross-sectional area at the gas control region.

  • Patent number: 9702325
    Abstract: A gas injector for injecting gaseous fuel includes: a valve body; an outer needle which is a hollow needle; an inner needle disposed in a hollow region of the outer needle; and an actuator system configured to actuate the outer needle and the inner needle independently of each other in each case. A first sealing seat is provided between the valve body and the outer needle, and a second sealing seat is provided between the outer needle and the inner needle.

  • Patent number: 9683519
    Abstract: A gas injector for the direct injection of gaseous fuel into a combustion chamber of an internal combustion engine, which includes a valve seat, a valve needle having a sealing region, the valve needle releasing a first cross-sectional area at the valve seat in response to a lift, a component surrounding the valve needle, and a gas control region, which is situated directly next to the sealing region, the gas control region providing a constant cross-sectional area between the valve needle and the component surrounding the valve needle across a lift length from a first lift position to a second lift position.

  • Patent number: 7380434
    Abstract: A device for positioning a component part in an inclined position, having a mounting support unit which is accommodated in a support of a base for tilting about at least one axis of the component part, and having an actuator unit which tilts the mounting support unit at a specified angle of inclination about the at least one axis of the component part, the mounting support having at least one coupling element which is supported on at least one counter-support of the actuator unit, which is movable relative to the at least one coupling element, in order to position the mounting support unit with the component part in the inclined position.
