Abstract: An ejector device having a base body that includes a suction chamber for sucking in a suction medium, a mixing channel for mixing a propelling medium with the suction medium, and a drive nozzle device for generating and directing a propelling medium jet along a jet direction from the suction chamber and into the mixing channel. The ejector device also includes a fastening device for fastening the base body of the ejector device to a suction channel. The fastening device also includes at least one of a translational locking device for avoiding a translational movement of the base body relative to the suction channel in a direction running parallel to a center axis of a connecting piece of the suction channel and a rotational locking device for preventing the base body from rotating relative to the suction channel.

Abstract: An oil sump is provided, including a bottom wall and a lateral outer wall, which in the assembled condition of the oil sump extends upwards from the bottom wall, as seen in the direction of gravity, and an oil storage region, which is arranged in an interior of the oil sump and, when the oil sump is in operation, is filled with oil up to a storage level, wherein the oil sump is better able to withstand heat and flame. The oil sump includes an oil cooling region, which is adjacent to the lateral outer wall and is filled with oil to a cool level, and a decoupling device for decoupling the cool level of the oil in the oil cooling region from the storage level of the oil in the oil storage region in a cool condition of the oil sump.
