Abstract: 1. A window (1) comprising a sash/frame structure (2,5) supporting a pane (3), a separate ventilation opening being adapted in the sash/frame structure (2,5) for flow communication between the exterior and interior sides of the window, characterized in that a circumferential valve housing (9) is inserted in the ventilation opening, the flow area of the valve housing being partially covered by a seat surface (12), and that a closing body (14) is journalled in the housing (9) so as to be pivotable between an open position in which the closing body (14) overlaps the seat surface (12), and a closed position in which the closing body (14) and the seat surface (12) together substantially cover the entire flow area of the valve housing (9). 2. A window according to claim 1, characterized in that the valve housing is in the shape of a preferably circularly cylindrical tube (9), and that the closing body (14) is pivotable about an axis coaxial with the tube (9). 3. A window according to claim 2, characterized in that the seat surface (12) supports a pivot bearing (13) for the closing body (14). 4. A window according to any one of the preceding claims, characterized in that the seat surface (12) and the closing body (14) are shaped as semi-circular plates. 5. A window according to any one of the preceding claims, characterized in that the valve housing (9) is provided with an end stop (26) for the closing body (14) so that further pivoting thereof is prevented when it reaches its fully open or fully closed position. 6. A window according to any one of the preceding claims, characterized in that the closing body (14) and the valve housing (9) have respective locking members (23,24) for mutual engagement in a number of different fixed positions of the closing body (14) in relation to the valve housing (9). 7. A window according to claim 6, characterized in that the respective locking members are formed as a projection (23) on the closing member (14) and a number of corresponding depressions (24) in the seat surface (12). 8. A window according to any one of the preceding claims, characterized in that the closing body (14) can be sealed in a position in relation to the valve housing (9). 9. A window according to any one of the preceding claims, characterized in that the sash/frame structure (2,5) is composed of a sash (2) and a frame (5), the sash (2) supporting the pane (3) and being openably journalled in the frame (5), that the sash (2) has a top member (6) whereby, parallel therewith, a handle (7) extends for operation of a locking mechanism (11) for the window (1), and that the valve housing (9) is arranged at the top member (6) behind the handle (7) so that in the closed position of the window (1) the handle (7) covers the valve housing (9) at least partially towards the interior side of the window (1). 10. A window according to claim 9, characterized in that an elongated ventilation slot is formed in the top member (6) of the sash (2) for flow communication between the exterior and interior sides of the window (1), the slot being closable by operation of the handle (7) by means of a ventilation flap hinged to the top member (6), and that the valve housing (9) is inserted in the ventilation flap.
