The housing of the diaphragm drive and the housing of the seat are joined together by means of a panel the shape of which is a circular sector. The three elements make the body of the hand-operated aeration regulator. The body is screwed down to structural elements of the window. The driving of the hand-operated aeration regulator is realized by means of a drum and a slide. The drum has a screw line cut on its surface. The slide is placed in this screw line and
Is simultaneously coupled with the insert closing the end of the diaphragm panel. The slide has a locking lip and the insert has a groove which help to join the two elements together. The drum is set in rotation manually with the help of a string reeled on a spool which Is the part of the drum. The ends of the string are reeled in opposite directions which enables the drum to move both to the right and to the left and as a consequence it enables to open or to close the gap. The insert closing the diaphragm panel has a tapped hole and a screw hi It which enables to regulate the dimension of the gap between the surface of the window frame and the diaphragm.
The d nention of the gap determines the infiltration of the intake ventilator in Its closed position. Owing to this solution the infiltration can be regulated.
In the consequence of this it ensures proper ventilation and substantially reduces energy consumption during heating season
