A Venturi pump used for sucking powder from a supply, diluting the same, then feeding it to a gun via a conveyor pipe. The pump comprises an outer body, at least one powder suction duct, at least two air connections, of which a first air connection is capable of supplying an injector to create a vacuum inside the suction duct and a second air connection is capable of supplying a dilution air circuit separate from the powder flow. The pump including at least one powder outlet nozzle centered on an axis of diffusion, the inlet of which is located downstream from the first air connection and the suction duct. At least one protection barrier contains a non-return valve disposed inside the dilution air circuit and at least one outlet tip of the dilution circuit disposed around the nozzle and also connected to the conveyor pipe.

The invention relates to an electrostatic projector (P) comprising: an insulation body (); a rotatably movable projection member (); rotational driving means (); high-voltage power supply means (); conducting elements (); a detection device () for evaluating the rotation speed of the projection member (), the detection device () including at least one target () on a rotary component and a sensor () adapted for detecting the or each target. The projector (P) further includes at least one insulating wall () that defines a housing () surrounding the sensor () for insulating the entire sensor () from the conducting elements (). The sensor () is separated from the space (V) scanned by the rotating target () by an essentially axial detection distance (H).

A system for continuously metering and transporting a powder comprises means (-) for fluidizing (F) the powder in a closed reservoir (), a tube () dipping into the fluidized powder (L) and discharging (B) to the outside of the reservoir (), and means (S, C) for pressurizing the reservoir. The system further comprises supply means (C) for continuously supplying pressurizing gas from the reservoir () to a chamber (V) for mixing the gas with fluidized powder leaving the tube (), said supply means (C) being equipped with or constituting a constriction (R) to the flow of the pressurizing gas. A hose () for transporting the powder mixed with the pressurizing gas is connected to the downstream end of the mixing chamber (V).
