Abstract
A device for centrifugal spraying of a liquid product. The device includes a rotary electric motor movable in rotation about an axis and arranged in a concentric sleeve. The centrifugal spraying device is configured so as to be able to prevent penetration of liquid into the electric motor without resorting to static sealing members such as sealing gaskets or sealed ball bearings, by taking advantage of the fast rotation of the motor to create an air overpressure in the vicinity of the axis of rotation of the motor, resulting in directing all of the liquid so that it gets away from the axis of rotation of the motor.
