Abstract
A two-fluid nozzle, constituted by a gas inlet and a liquid inlet; a first mixing chamber having a gas feed element connected to the gas inlet for feeding a gas along an axial center line in a direction toward a discharge end of the nozzle and having a liquid feed element for feeding a liquid into the outer periphery of the gas at the downstream end of the gas inlet; a substantially uniform diameter rectifying chamber opening out of the first mixing chamber and extending along the axial center line toward the discharge end for receiving the mixture of gas and liquid and conveying it therealong; a second mixing chamber having a larger diameter than the rectifying chamber and into which the downstream end of the rectifying chamber opens, the second mixing chamber having a wall face at the downstream end thereof spaced from and opposed to the downstream end of the rectifying chamber and against which the outer peripheral portion of the mixture of gas and liquid discharged into the second mixing chamber from the rectifying chamber collides; and a nozzle tip on the downstream end of the second mixing chamber having a discharge opening at a discharge end thereof and a jetting chamber ext…
