The mask is provided with a manually adjustable valve 15. In a first position, the valve maintains the said communication between the first connection 19 and the space 12 and between the second connection 18 and the edge region 4, 5. In a second position, the valve maintains communication between the first connection 19 and the second connection 18. <IMAGE> |
