Abstract
A sprayer includes a nozzle through which gas is to be ejected with positiveness and uniformity. The sprayer is provided with a nozzle having inner tubes through the interior of which liquid is to pass and an outer tube receiving the inner tubes therein and allowing gas to pass through a space defined with the inserted inner tubes. The inner tubes have respective liquid orifices through which liquids are to be ejected. The outer tube is arranged therein with the liquid orifices and a gas orifice for ejecting gas. When the nozzle is viewed from front, the outer peripheries of the liquid orifices each assume a circular form while the inner peripheries of the gas orifices are differently shaped to provide plural point contact between the outer periphery of the liquid orifice and the inner periphery of the gas orifice.
