A diaphragm pump wherein the diaphragm is deformable by the reciprocable armature of an electromagnet which is energizable at a selected frequency by a timer circuit and at random frequency by a pulse generator. The pulse generator is connectable with the electromagnet by a cable having separable male and female coupling elements which automatically deactivate the timer circuit when the male coupling element is inserted into the female coupling element. A selector switch is provided to deactivate the timer circuit independently of the coupling elements. A knob serves to adjust a potentiometer of the timer circuit simultaneously with closing of the selector switch so that the frequency at which the timer circuit can energize the electromagnet is reduced to a minimum value.

Fluid flow machine with an electromagnetically operated diaphragm pump

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.
