Abstract:
A fluid delivery device for supplying a linear pulsating discharge of a first fluid from a source of the first fluid, comprising:a housing; an elongated cylindrical chamber within the housing, the chamber having an inside diameter and a length, the length being greater than the inside diameter; an elongated cylindrical rotor rotatably mounted in the chamber, the rotor having an outside diameter sized to substantially wipe the inside diameter of the chamber and having a plurality of grooves; a first fluid injector passage in the housing connected to the first fluid source and to the chamber, the first fluid injector passage comprising a first fluid injection channel shaped to accelerate the first fluid entering the first fluid injector passage and to direct the accelerated first fluid into the grooves of the rotor, causing the rotor to rotate; and a linear fluid discharge nozzle in the housing connected to the chamber, the discharge nozzle, as a whole, comprising a linear structure for ejecting a linear pulsating stream of the first fluid from the device, the linear pulsating stream essentially extending across the entire length of the elongated chamber.
