Abstract: A running gear for a gondola of a gondola lift system for use with support means of the gondola lift system. The running gear includes a running gear frame coupleable to a cabin of the gondola via a support arm, and at least one running wheel, rotatably mountable on the running gear frame, for traveling on a running device of the support means. The running gear includes a guide unit coupleable to the running gear frame via a swivelable cantilever. The guide unit includes a guide element for a form fit with one of two guide devices of the support means, and an actuator element for the form fit with one of two actuator devices of the support means that are rigidly coupled to the running device for deflection of the running device. The running gear includes a control element for swiveling the cantilever together with the guide unit.

Abstract: A drive module for a self-driving vehicle of an elevated-track-type support structure. The drive module is able to be connected to a support arm for a gondola.

Abstract: Transfer equipment for self-propelled cars on a route network similar to an elevated railway. The route network includes at least one track element and at least one intersection, turning or end point, in the region of which the self-propelled car can be transferred from the at least one track element onto an adjustably arranged support unit.

Abstract: An elevated railway-like transport system. The system includes a carrier system with rail-like or cable-like carrier elements that are fastened in the area of portal-like support elements, and includes self-propelled carriages, each of which includes a drive unit that cooperates with the carrier elements, and a gondola that is connected to the drive unit via a carrier device, preferably in the form of a carrying arm, and that is used for passenger transport and/or cargo transport. The carriages are movable independently of one another along the carrier elements, and a distance is formed between two successive carriages on the same carrier element.

Abstract: A drive unit for a self-driving vehicle of an elevated-track-type support structure. The drive unit has at least one electric motor for moving the drive unit along the support structure, the at least one electric motor being able to be at least indirectly driven indirectly with the aid of a first energy supply, and the first energy supply having at least one contact element, which is developed to interact with an electrical conductor immovably situated on the support structure.

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.

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.

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.

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.
