PUMP MECHANISM ACTIVATED BY SINGLE ROTATION FOR CONTINUOUS AEROSOL SPRAYING Russian patent published in 2022 - IPC B05B11/02 

FIELD: sprayers.

SUBSTANCE: method for release of a product from an inner volume of a container, to which a power unit is attached, includes stages, at which: (1) a sleeve of a drive of the power unit is rotated in one direction by 360° or less relatively to the container to draw some amount of the product from the specified inner volume into a pumping chamber and to exert pressure on the pumping chamber; (2) a temporary pressure on the drive of the power unit is provided to open a valve connected via fluid to the pumping chamber and normally shifted to a closed position to release part of the product from the pumping chamber through a nozzle during a time interval, when the temporary pressure on the drive is provided; (3) pressure relief from the drive is provided to ensure the possibility of return of the valve to the closed position before all the product drawn into the pumping chamber at the stage (1) is released through the nozzle; (4) pressure on the drive and pressure relief from it are repeated sequentially one or more times until all the product drawn into the pumping chamber at the stage (1) is released through the nozzle; and (5) stages (1)-(4) are repeated to draw additional amounts of the product from the inner volume of the container and to release additional amounts of the product through the nozzle; moreover, during the time, when the product is released from the container, the rotation of the power unit relatively to the container is prevented, and the rotation of power unit 2 relatively to the container is constantly prevented in the direction opposite to the specified one direction of rotation at the stage (1).

EFFECT: increase in the efficiency of aerosol spraying.
