Abstract

UN SISTEMA MOTRIZ (10,10A) PARA GIRAR UN DISCO (22) INCLUYE UN ALOJAMIENTO (28,28A) QUE TIENE UN ELEMENTO PLANAR (12,12A) CON UNA SUPERFICIE DE TRABAJO (14) QUE INCLUYE UN EJE (18) QUE FACILITE EL MOVIMIENTO ROTACIONAL DEL DISCO (22) RELATIVO AL MONTAJE MOTRIZ. UNA PLURALIDAD DE ORIFICIOS (23) SE EXTIENDEN A TRAVES DEL ELEMENTO PLANAR EN UN ANGULO AGUDO RELATIVO A LA SUPERFICIE DE TRABAJO (14) Y ESTA DISPUESTO EN UNA SERIE CIRCULAR. UN MONTAJE DE CONDUCTO (26,26A) DISTRIBUYE EL LIQUIDO AL ALOJAMIENTO (28,28A). EL LIQUIDO SALE A TRAVES DE LAS SALIDAS DE ORIFICIO (24) PARA PROVEER UNA FUERZA MOTRIZ PARA ROTAR EL DISCO (22) ALREDEDOR DEL EJE (18), MIENTRAS TAMBIEN PROVEER UNA FUERZA SOPORTE PARA SOPORTAR EL MEDIO.
