Regulator for suction force of conventional vacuum cleaner

摘要

The regulator has an opening (3) and a leaf spring (5). By pressure reduction it compensates externally for the lack of air passed to the vacuum cleaner to prevent disturbances at the nozzle or brush, that is, the use of nozzles and brushes with very small air-permeable openings is made possible. It is attached between the hose and the cleaner itself. The regulator has a plastic housing (1). Air can flow through the opening. With the plastic grille (6) one can close the opening if necessary when the total suction force of the cleaner is needed. The opening is covered inside by the spring, the spring being screwed or riveted on one side.
