Abstract
UN CIRCUITO HIDRAULICO PARA UN VEHICULO DE TRABAJO QUE TIENE UNA PLURALIDAD DE ACCIONADORES HIDRAULICOS. COMPRENDE UNA PRIMERA BOMBA, UNA SEGUNDA BOMBA, UN PRIMER ACCIONADOR, UN SEGUNDO ACCIONADOR, Y UNA VALVULA SELECTORA QUE TIENE UNA PLURALIDAD DE POSICIONES DE CONTROL. LA VALVULA SELECTORA ES CONMUTABLE ENTREUNA PRIMERA POSICION PARA CONECTAR LA PRIMERA BOMBA AL PRIMER ACCIONADOR Y LA SEGUNDA BOMBA AL SEGUNDO ACCIONADOR, Y UNA SEGUNDA POSICION PARA CONECTAR LA PRIMERA BOMBA Y LA SEGUNDA BOMBA AL SEGUNDO ACCIONADOR. ESTE CIRCUITO INCLUYE UNA PRIMERA VALVULA DE DESCARGA DISPUESTA ENTRE LA VALVULA SELECTORA Y LA PRIMERA BOMBA, Y UNA SEGUNDA VALVULA DE DESCARGA DISPUESTA ENTRE LA VALVULA SELECTORA Y LA SEGUNDA BOMBA. LA PRIMERA VALVULA DE DESCARGA ESTA AJUSTADA A UNA PRESION DE ALIVIO MAS ALTA QUE LA SEGUNDA VALVULA DE DESCARGA.
