Abstract

The throttle arrangement for pipes in a ventilation system consists of pipe pieces 2 which are arranged in succession and partly overlap one another and are provided with holes 1 which can, as required, be closed in order to bring about throttling. In the open position, the holes 1 in the mutually overlapping parts of the pipe pieces 2 lie opposite one another, and, in the closed position, the pipe pieces are rotated in relation to one another in such a manner that the holes 1 in the consecutive pipe pieces 2 are closed. <IMAGE>
