Abstract
EL VARIADOR CONTIENE UNA BOMBA DE PISTONES RADIALES (3) DE EXCENTRIDAD VARIABLE, UN MOTOR HIDRAULICO (4), IGUALMENTE CON PISTONES RADIALES, Y UN CUERPO CENTRAL (56) EQUIPADO DE DISTRIBUIDORES FRONTALES (30 Y 31) QUE ESTAN PUESTOS EN COMUNICACION, POR LAS ABERTURAS DE CONDUCTOS (32 Y 33) CON LAS CAVIDADES CILINDRICAS RADIALES DE DICHA BOMBA, RESPECTIVAMENTE DE DICHO MOTOR. MODIFICANDO LA EXCENTRICIDAD DE LA BOMBA, SE HACE VARIAR EL CAUDAL DEL LIQUIDO EN ESTA, DETERMINANDO ASI UNA VARIACION DEL NUMERO DE REVOLUCIONES DEL MOTOR HIDRAULICO.
