  • Patent number: 5730587
    Abstract: An improved dual air pump in which the diaphragm elements of the pump that cover the pump chamber are connected to an elastic band which is shaped as an inverted U, having magnet mounting surfaces provided proximate the extremities of the downwardly depending sides of the band. Support of this vibrating structure is obtained solely from the diaphragms themselves which are attached proximate the center of the sides of the elastic band. The magnetic mounting surfaces of the elastic band are superimposed over a conventional electromagnetic drive unit which, when energized with an alternating voltage, will alternately attract and repel the permanent magnets mounted on the magnet mounting surfaces so as to alternately extend and compress the flexible diaphragm elements to create a pumping action.
