Rune Narfgren holds a patent for a connecting valve. This invention relates to a connecting valve designed for connecting the hose of vacuum cleaning equipment into the suction duct of a built-in cleaning system. The connecting valve is strategically positioned behind a flap cover for the suction duct opening. It comprises a pair of complementary valve elements that mate in a closed position to seal the duct opening. When open, these elements provide a straight tubular passageway for the hose of the vacuuming equipment. Each valve element is formed from a segment of a tubular pipe and is pivoted adjacent to the duct opening.
