Abstract

The exhaust gas cooler (1) has a bypass (2) and an associated exhaust gas delivery line (3) and first and second choke elements (4,5) for regulating and/or controlling the throughput of exhaust gas. Both choke elements are arranged in the exhaust gas delivery line. The first choke element has a frame (6) that can be introduced into the exhaust gas delivery channel.
