Abstract

VALVULA DE CONTROL PARA UN ELEVADOR HIDRAULICO PROVISTO DE UN OBTURADOR (2) DE REGULACION DE VELOCIDAD QUE SE MUEVE CON EL FLUJO DEL FLUIDO HIDRAULICO Y CUYA POSICION DETERMINA EL FLUJO DEL FLUIDO HIDRAULICO A EL CILINDRO DE ACCIONAMIENTO DEL ELEVADOR, Y DE UN SISTEMA DE CANAL HIDRAULICO (1) QUE FORMA UN CIRCUITO CERRADO. UN PROBLEMA DE LOS ELEVADORES HIDRAULICOS, ES QUE CUANDO EL ELEVADOR ESTA LLEGANDO A SU PUNTO DE PARADA, ES DIFICIL LLEVAR A CABO UNA DECELERACION CONSTANTE INDIFERENTE A LAS VARIACIONES DE LA TEMPERATURA DEL FLUIDO HIDRAULICO. LA INVENCION RESUELVE ESTE PROBLEMA, YA QUE EL SISTEMA DE CANAL HIDRAULICO (1) ESTA PROVISTO DE UN COMPONENTE DE RESISTENCIA DE FLUJO (9) COLOCADO CERCA DE CUALQUIER EXTREMO DEL OBTURADOR DE REGULACION DE VELOCIDAD, VARIANDO LA FIJACION DE DICHO COMPONENTE SEGUN LA TEMPERATURA DEL FLUIDO HIDRAULICO.
