Abstract

UNA DISPOSICION DE UNA VALVULA DE CONTROL PARA UN SERVOMOTOR ACTIVADO POR UNA PRESION DIFERENCIAL (10) EN DONDE UNA LLAVE (64) SE METE EN UNA RANURA (38) QUE HAY EN EL CUBO (28) PARA RETENER LA VALVULA DE CONTROL (28) Y COLOCAR LA VALVULA DE CONTROL (28) EN UNA POSICION QUE SEPARE UNA PRIMERA CAMARA (18) DE UNA SEGUNDA CAMARA (20) EN AUSENCIA DE UNA FUERZA DE ENTRADA QUE ESTA SIENDO APLICADA PARA ACTIVAR LA VALVULA (28). LA VALVULA DE CONTROL (28) SE MUEVE INMEDIATAMENTE EN RESPUESTA A UNA FUERZA DE ENTRADA PARA INICIAR EL DESARROLLO DE LA PRESION DIFERENCIAL Y ELIMINAR SUSTANCIALMENTE, COMO RESULTADO, EL TIEMPO OPERACIONAL PARA LLEVAR A CABO UNA FUNCION DE FRENADO.
