#CMT# #/CMT# The ventilation installation (1) comprises a housing (2) with a ventilation through passage (3) extending between outer (4) and outer (5) areas of a building. A valve (6) is fitted in the through passage for its closure. In the installation is an adjustable operating component (7) and a transmission component (8), which by means of an engagement component (9) transmits the movement of the operating component to the valve. #CMT# : #/CMT# The engagement component is so arranged that it can assume two positions at least in relation to the transmission component or the valve, so that for an individual displacement of the operating component in the positions a differing state of the valve is achieved. The operating component is directly connected via a fixed connection (transmission component and operating component as an entity). In this version, the operating component is formed as a rotatable male part. #CMT#USE : #/CMT# As a ventilation installation for a building. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure presents a cross-section of the ventilation installation. 1 : ventilation installation 2 : housing 3 : through passage 4,5 : outer and inner areas of building 6 : valve 7 : operating component 8 : transmission component 9 : engagement component.
