Abstract
MAQUINA HIDRAULICA DEL TIPO CON ENGRANAJES QUE COMPRENDE AL MENOS UN JUEGO DE DOS PIÑONES COOPERANTES DISPUESTOS PARA GIRAR ENTRE DOS BRIDAS MOVILES EN TRASLACION EN CAVIDADES REALIZADAS EN UN CARTER MEDIANO CERRADO SOBRE SUS DOS LADOS OPUESTOS POR CARTERES ANTERIOR Y POSTERIOR, ESTANDO CADA BRIDA SENSIBLEMENTE EQUILIBRADA EN PRESION POR LA DISPOSICION ENTRE ESTA BRIDA Y EL CARTER ADYACENTE DE UN SISTEMA DE JUNTA CONVENIENTE, CARACTERIZADO EN QUE LAS BRIDAS (14, 15) QUE SOPORTAN LOS PIÑONES (13, 17) ESTAN MONTADAS FLOTANTES EN EL INTERIOR DEL CARTER MEDIANO (3) Y EN QUE UNOS MEDIOS DE PRESION (49) APLICAN LAS BRIDAS (14, 15) CONTRA EL CARTER MEDIANO Y PROVOCAN UNA PRESION DIFERENCIAL QUE HACE APRETAR LAS BRIDAS (14, 15) CONTRA LAS CARAS LATERALES DE LOS PIÑONES (13, 17).
