Abstract
UNA VALVULA DE DOBLE EFECTO (10) QUE TIENE UN MIEMBRO DE VALVULA (30) QUE INCLUYE UNA PRIMERA Y SEGUNDA SECCION (32, 36) COLOCADAS EN EL INTERIOR DE LAS SECCIONES DE UN CONDUCTO DE DIAMETROS PEQUEÑO, REDUCIDO Y AGRANDADO LOCALIZADO EN EL CUERPO DE LA VALVULA (12). LA SECCION DE PEQUEÑO DIAMETRO COMUNICA CON UNA LINEA DE RETROLALIMENTACION DE FRENO (20), LA DE DIAMETRO REDUCIDO COMUNICA CON UNA ABERTURA DE SALIDA Y LA DE DIAMETRO AGRANDADO CON LA ABERTURA DE TOMA (50). LAS SECCIONES DE DIAMETRO SECUNDARIO DEL MIEMBRO DE VALVULA (30) INCLUYE UNA ABERTURA TRANSVERSAL (44) QUE CONDUCE A UNA CAMARA LOCALIZADA EN UN EXTREMO DEL MIEMBRO DE VALVULA (30). SE COLOCAN UNAS JUNTAS ESTANCO (60, 70) ALREDEDOR DE LA PRIMERA Y SEGUNDA SECCION (32, 36) Y EL MIEMBRO DE VALVULA ESTA SUJETO EN SU POSICION DE DESCANSO POR MEDIO DE UN MUELLE (80). COLOCADO ALREDEDOR DELA PRIMERA SECCION (32) DEL MIEMBRO DE VALVULA (30) SE ENCUENTRA UN MIEMBRO CON UN ORIFICIO (90) QUE SE MUEVE LIBREMENTE, QUE INCLUYE UN ORIFICIORADIAL (90) EN LA SUPERFICIE DEL ANTERIOR. LA SUBITA COMUNICACION DE LA ALTA PRESION DE FLUIDO A TRAVES DEL ORIFICIO DE ENTRADA (50) ORIGINA UN DESPLAZAMIENTO ALGO RETRASADO DEL MIEMBRO DE VALVULA (30) Y DEL MIEMBRO CON EL ORIFICIO MOVIL (90), Y EL DESPLAZAMIENTO DE MIEMBRO DE VALVULA OCASIONA QUE EL FLUIDO SE COMUNIQUE A TRAVES DEL MIEMBRO DE ORIFICIO MOVIL (90) OCASIONANDO QUE SE RESTRINGA LA COMUNICACION DEL FLUIDO CON LA ABERTURA DE SALIDA.
