The disclosure relates to an exhaust gas cooling device for an internal combustion engine, having a housing which can be connected to an exhaust gas line of the internal combustion engine and has an axis of symmetry and having a Venturi assembly coupled to the housing for introducing exhaust gas and ambient air and having an outlet line emitting an exhaust gas-ambient air mixture into the environment, wherein: the Venturi assembly has a Venturi channel which can be coupled fluidically to the exhaust gas line and an inlet opening delimited by the Venturi channel and the exhaust gas line for ambient air; the Venturi channel is used to conduct an exhaust gas-ambient air mixture and opens, with the inlet opening, into a mixing chamber; the Venturi channel has an outlet opening and the outlet opening has an inflow opening, wherein the outlet opening and the inflow opening are spaced apart from one another; the Venturi channel and the outlet line, with the inflow opening, open into the housing.

Exhaust gas cooling device

The disclosure relates to a retaining flange for a metering valve for an exhaust gas cleaning module of an exhaust gas system of a combustion engine, wherein the retaining flange has a base plate having a central recess with a central axis for receiving the metering valve, wherein the base plate has a mounting surface via which the retaining flange can be positioned on the exhaust gas cleaning module in the region of a supply opening of the exhaust gas cleaning module, wherein a valve surface is provided opposite the mounting surface against which the metering valve can be positioned and wherein at least one retaining arm having a retaining eyelet with a central axis and for a retaining means is provided, on which the metering valve can be at least indirectly fixed, such that the at least one retaining arm has a root connecting to the base plate, from which the retaining arm extends in the radial direction relative to the central axis and in the circumferential direction about the central axis, wherein the root and the retaining eyelet are arranged offset to one another in the circumferential direction.
