dispositivo para alimentação de suspensão ou líquido

摘要

The invention relates to a suspension or liquid supply device consisting of a vertical supply tube terminating in an end injector and having a nozzle holder. The invention includes a system for regulating the flow in discrete steps, provided with nozzles with different cross-sections, thereby dispensing with the need for flow restriction systems and valves which produce significant head losses. The supply device is essentially characterised in that the flow of liquid or suspension supplied by the device is not sensitive to changes in the viscosity of the liquid or suspension supplied.
