<p>The present invention may be used in the field of jet-generation techniques and essentially relates, in one embodiment, to a nozzle for a gas and liquid ejector. This nozzle includes a channel comprising an inlet portion that narrows in the flow direction as well as an outlet portion, wherein said portions are connected to each other. The surfaces of the inlet and outlet portions of the channel are further connected together so as to define a sharp edge. In another embodiment, the surfaces of the portion that narrows and of the outlet portion in the channel of the nozzle are connected together along a curved line having a curvature radius that does not exceed 0.5 mm. These structures provide for liquid- and gas-ejector nozzles that convert the potential energy of the liquid pressure at the inlet of the nozzle into a jet kinetic energy at the outlet of said nozzle while minimising the energy losses. These structures further improve the industrial production process of said nozzles.</p> |
