Abstract

VALVULA DE DESCARGA PARA FLUIDO HIDRAULICO. COMPRENDE UN PRIMER CONDUCTO (30) QUE DESEMBOCA EN UN TALADRO (14, 16) PREVISTO EN UN CUERPO (10), UNA COMUNICACION ENTRE ESTE PRIMER CONDUCTO (30) Y UN SEGUNDO CONDUCTO (34) QUE UNE UN CIRCUITO HIDRAULICO PRIMARIO BAJO PRESION CON DICHO TALADRO (14, 16), ESTANDO PROVISTO EN LA POSICION DE REPOSO DE UN ELEMENTO VALVULA CUANDO LA PRESION DENTRO DEL PRIMER CONDUCTO (30) ES MAS BAJA QUE UN UMBRAL DETERMINADO POR LA CARGA PREVIA DE UN MEDIO ELASTICO QUE SOLICITA EL ELEMENTO VALVULA A LA POSICION DE REPOSO, SIENDO LA COMUNICACION INTERRUMPIDA CUANDO LA PRESION DEL PRIMER CONDUCTO (30) ALCANZA SENSIBLEMENTE EL UMBRAL. DE ACUERDO CON LA INVENCION, UN AUMENTO DE LA PRESION DEL PRIMER CONDUCTO HASTA MAS ALLA DEL UMBRAL TIENE POR RESULTADO PROVEER UNA COMUNICACION ENTRE ESTE PRIMER CONDUCTO (30) Y UN TERCER CONDUCTO (38) UNIDO A UN CIRCUITO DE BAJA PRESION. ACTUA COMOVALVULA PROPORCIONAL FACILITANDO LA CONDUCCION. SE APLICA ESPECIALMENTE A DIRECCION DE VEHICULOS.
