ABSTRACT:
The combination valve comprises a tubular center part, a gas inlet which is arranged on the outer shell of the tubular center part, a gas outlet A which is arranged adjacent to the gas inlet on the outer shell of the tubular center part, a first branch which is arranged opposite the gas outlet on the outer shell of the tubular center part, and a second branch which is arranged opposite the gas inlet on the outer shell of the tubular center part. The first branch is connected to the second branch via a cooler. A rotary slide is mounted centrally in the tubular center part such that it can rotate about the longitudinal axis of the tubular centre part. Depending on the operating state, the rotary slide shuts off at least partially the gas inlet, the gas outlet, the first branch and the second branch.
