<p>A device for selective flow connection of exhaust piping of cutting machinery having an exhaust fan is described, comprising a distributor connected on one side to the exhaust fan and on the other side to the exhaust piping and comprising a switching device for closing and opening the exhaust piping connected to the distributor. In the interests of creating advantageous structural conditions it is proposed that the distributor forms a pot-shaped housing (1) for the switching device, whose floor (2) bears the connection (3) for the exhaust fan and whose peripheral wall (4) bears the connections (5) for the exhaust piping, that the switching device presents a pot-shaped housing insert (6) which is connected to the housing floor (2) with its peripheral wall (8) enclosing the connection (3) for the exhaust fan and seals off the housing (1) with its floor (7) in the manner of a cover, and that a passageway (10) aligning in individual adjustable settings with a connection (5) for the exhaust piping is provided in the peripheral wall (8) of the rotatably adjustable housing insert (6) closing off the connections for the exhaust piping.</p> |
