Abstract
Abstract Nozzle for the deposition of a thin coating layer on a sheet of glass using the process of pyrolysis starting with a gas, known as CVD. The invention provides a nozzle arranged above the sheet of glass (10) and comprises a gas delivery (27), a central block (34) under which the gas travels, a suction channel (40) and a downstream toe (42) adjacent to the suction channel, raised in relation to the sheet of glass, in comparison with the central block (34). This nozzle permits the deposition of layers of greater thickness and/or involving high gas flow rates. <IMAGE>
