METHOD OF AUTOMATIC ADJUSTMENT AND BALANCING VIBRATION PUMP VOLUME CAPACITY IN VARIOUS OPERATING CONDITIONS AND VIBRATION PUMP TO THIS EFFECT (VERSIONS) Russian patent published in 2008 - IPC F04F7/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to production of electromagnetic-drive vibration pumps. Method of volume capacity adjustment consists in connecting the vibration pump, via the capacitor to the mains, the said pump incorporating an electromagnetic drive made up of a magnetic circuit with coils and an armature con-rod linked to the flexible and damping suspensions. Coils are wound up to ensure the magnetic circuit induction saturation and to turn them into a ferrous-resonance parametric oscillation circuit. Damping suspension area varies with the elastic suspension rigidity so as to reduce mean air gap between the magnetic circuit and armature by 30% to 40%.

EFFECT: higher reliability in operation without water, increased efficiency and pump longer life.
