Abstract
PERFECCIONAMIENTOS EN VARIADORES DE VELOCIDAD HIDRAULICOS, CONSTITUIDOS POR UN BLOQUE SOLIDARIO DE CONJUNTO VARIADOR QUE ENGLOBA: CILINDRO DE HIDROBOMBA, CILINDRO DEL HIDROMOTOR, SUS TAPAS EXTREMAS Y PLACA INTERMEDIA CON LUMBRERAS O PASOS DEL FLUIDO DE LA HIDROBOMBA AL HIDROMOTOR EN ALTA PRESION Y DEL HIDROMOTOR A LA HIDROBOMBA EN BAJA PRESION PARA CERRAR EL CIRCUITO. LOS EJES DE LOS ROTORES DE LA HIDROBOMBA E HIDROMOTOR TIENEN UN EJE GEOMETRICO COMUN Y ESTATICO RESPECTO AL EXTERIOR, SOBRE EL QUE PUEDEN GIRAR INDEPENDIENTEMENTE, SIENDO ESTE MOVIMIENTO DE GIRO SU UNICO MOVIMIENTO POSIBLE. EL GIRO DEL CONJUNTO VARIADOR ESTA LIMITADO RESPECTO A UN EJE GEOMETRICO FIJO RESPECTO AL EXTERIOR DISTINTO DEL EJE GEOMETRICO DEL CILINDRO DE LA HIDROBOMBA Y DEL EJE GEOMETRICO DEL CILINDRO DEL HIDROMOTOR Y TAMBIEN DISTINTO DEL EJE GEOMETRICO COMUN DE LOS ROTORES. EL GIRO DEL CONJUNTO VARIADOR, QUE SE PROVOCARA DESDE EL EXTERIOR PROVOCA QUE, EL CILINDRO DE LA HIDROBOMBA Y EL CILINDRO DEL HIDROMOTOR APROXIMEN O ALEJEN SUS EJES GEOMETRICOS DE LOS DE SUS RESPECTIVOS ROTORES, PROVOCANDO LA VARIACION EN LA RELACION ENTRE LA VELOCIDADES DE GIRO DEL ROTOR DE LA HIDROBOMBA Y DEL ROTOR DEL HIDROMOTOR.
