SUCTION VALVE OF A HOUSEHOLD VIBRATORY PUMP

摘要

The invention relates to vibratory pumps. Elastic suction valve of the pump has form of a disc symmetrical with respect to the vertical and horizontal axes of the disc with thin working edge and massive central section with opening. At operation of the pump peripheral thin part of the valve is additionally deflected under effect of forces of inertia, this promotes increase of continuous flow opening for liquid. The valve proposed promotes decrease of consumption of drive power and increase of efficiency of the pump.
