A coolable metering module (2) has an inner sleeve (6) which is configured for receiving an injector (4) which extends substantially in a longitudinal direction, in such a way that the inner sleeve (6) is arranged, at least over a part region of the longitudinal extent of the injector (4), around the circumference of the latter, and an outer sleeve (9) which surrounds the inner sleeve (6) in such a way that a volume (11) for receiving a fluid coolant is formed between the inner sleeve (6) and the outer sleeve (9). The inner sleeve (6) has a collar (7) which is configured for receiving and guiding an end region (9b) of the outer sleeve (9), in order to connect the outer sleeve (9) and the inner sleeve (6) to one another. |
