초록

A gas-mixing device for respirators can be used both in stationary operation and in mobile operation. The gas-mixing device has a storage tank (5), into which compressed air and oxygen can be introduced by dispensing valves (3, 8). In addition, a blower (10), which draws in gas from the environment (11), is connected to the storage tank (5). To dispense gas from the pressurized gas sources (4, 6) by means of the dispensing valves (3, 8), a first operating pressure level is set in the storage tank (5). When changing over to the blower operation, the opera...
