Abstract

VALVULAS DIRIGIDAS HIDRAULICAMENTE CON UNA PIEZA PARINCIPAL DE LA VALVULA (16) Y CON UNA PIEZA DE PILOTO DE LA VALVULA (60) SE DIRIGEN, DONDE UNA CAMARA DE PILOTO (50) SE UNE A ELECCION CON LA ENTRADA (30) Y/O SALIDA (34) DE LA VALVULA (10). PARA MOVILIZAR LA PIEZA PRINCIPAL DE LA VALVULA (16) Y PARA ABRIR Y CERRAR EL ASIENTO DE LA VALVULA PRINCIPAL (36), NORMALMENTE ES NECESARIO UNA DIFERENCIA DE PRESION ENTRE LA ENTRADA (30) Y LA SALIDA (34). ESTA EXIGENCIA CARECE CUANDO ENTRE LA PIEZA PILOTO DE LA VALVULA (16) HAY DISPUESTOS RESORTES (70, 82) QUE TRANSMITEN FUERZAS SOBRE LA PIEZA PRINCIPAL DE LA VALVULA (16), QUE ESTAN ENDEREZADOS DE TAL MANERA, QUE SE ESFUERZA LA PIEZA PRINCIPAL DE LA VALVULA (16) PARA SEGUIR LOS MOVIMIENTOS D ELA PIEZA DE PILOTO DE LA VALVULA (60). DE ESE MODO PUEDEN VENCER LAS RESISTENCIAS D ELA JUNTA LISA DE LA PIEZA PRINCIPAL DE LA VALVULA (16). LAS VIBRACIONES DE FRECUENCIA ALTA DE LA VALVULA SE PUEDE DISMINUIR DE TAL MANERA, QUE SE PREVEEN UNA CAMARA DE AMORTIGUACION 864) CUYO VOLUMEN SE MODIFICA EN DEPENDENCIA DEL MOVIMIENTO DE LA PIEZA PRINCIPAL DE LA VALVULA (16). LA CAMARA DE AMORTIGUACIONES ESTA UNIDA CON LA CAMARA DE PILOTO (58) SOBRE EL DIAGRAGMA DE AMORTIGUACION.
