An inlet flow connection (8) of the valve (2) casing (5) passes the gases to an inlet slot (13). The inlet slot is formed in a rotary- and/or sliding control plug (10), held in a flow chamber (15) in the casing. The first outlet slot (16) of this chamber is connected to an exhaust outlet line (18), through a transfer chamber (17). The second outlet slot (22) of the flow chamber (15) is connected to the inlet cross section (26) of the distribution chamber (23) by a heat exchanger section (6). In its central position, the plug (10) closes the inlet slot (13) with its cylindrical surface (39). Plug end positions are controlled. With the plug at one end, gases are passed through the inlet slot (13) to the first outlet slot (16) and towards the bypass line (18) connected to it. With the plug at the other end, the inlet slot (13) is connected to the second outlet gap (22) sending flow towards the heat exchanger (6). |
