Abstract

The invention relates to a device for metering fluid, particularly for the metered injecting of a reduction agent into the exhaust tract of an internal combustion engine, which has an electrically controllable metering valve (11) having a valve housing (16), having an inlet opening and a metering opening (14, 15) for the fluid, and a cooling module (12) to which a coolant is applied for cooling the metering valve. In order to achieve a permanent fording ability of the device, the metering valve (11) is hermetically sealed in the cooling module (12) and only the inlet opening and the metering opening (14, 15) of the valve housing (13) are exposed.
