Abstract

EN UNA CAJA DE VALVULAS (30) SE HAN DISPUESTO DOS ASIENTOS DE VALVULAS (32,34) EN LOS QUE UN CUERPO (40) CONJUNTO DE VALVULAS ES INSTALABLE. EL CUERPO DE VALVULA (40) ESTA LEVANTADO O ALCANZADO, EN UNA POSICION DE UN ELEMENTO DE ACCIONAMIENTO (38), MEDIANTE EL PRIMER ASIENTO (32) DE VALVULA EXLUSIVAMENTE. A TAL EFECTO, DOS CAMARAS (24,26) ESTAN UNIDAS DEL AMPLIFICADOR DE FUERZA DE FRENADA (10) Y A SU VEZ SEPARADAS DE LA ENTRADA O ADMISION DE AIRE (50). EN OTRA POSICION DEL MIEMBRO O ELEMENTO (38) DE MANIOBRA, EL CUERPO DE VALVULA (40) ESTA ALZADO DEL SEGUNDO ASIENTO DE VALVULA (34), A LO CUAL AMBAS CAMARAS (24, 26) ESTA SEPARADAS UNA DE OTRA Y UNA DE ELLAS ESTA EN COMUNICACION CON LA ENTRADA O ADMISION (50) DE AIRE. ESTE GRUPO CONSTRUCTIVO O UNIDAD NORMALIZADA (28) TIENE UN CANAL ADICIONAL (80) DE AIREACION O VENTILACION, QUE DESEMBOCA EN LA CAMARA (26) CONECTABLE CON LA ADMISION DE AIRE (50) Y ESTA GOBERNADO O ACCIONADO POR UNA VALVULA (66,72) ADICIONAL. ESTA VALVULA (66,72) SE ABRE MEDIANTE EL MOVIMIENTO DEL ELEMENTO DE ACCIONAMIENTO (38) EL CUAL REBASA EL MOVIMIENTO NECESARIO PARA ELEVAR EL CUERPO (40) DE VALVULA DEL SEGUNDO ASIENTO (34) DE VALVULA.
