ABSTRACT:
The membrane of a diaphragm pump is deformable by the reciprocable armature of a cylindrical electromagnet which is installed in the interior of a plastic housing adjacent to a partition which separates the winding or windings of the electromagnet from the casing of the pump and which carries the casing as well as the electromagnet. That section of the housing which surrounds the electromagnet is a relatively thin cylinder having circumferentially extending heat-dissipating ribs and a cylindrical internal surface which defines with the cylindrical external surface of the electromagnet a gap of constant width. The area around the cylindrical section of the housing is unobstructed, and the housing further includes a larger section which is integral with the cylindrical section, which is rigid with a foot extending well below the electromagnet to enhance the stability of the machine, and which confines a control circuit for the electromagnet.
