Abstract

Una junta hidráulica giratoria (24) para uso en un ventilador de flujo axial, que comprende: una carcasa (54); un elemento interior (56) acoplado de manera giratoria a la carcasa, incluyendo el elemento interior un orificio longitudinal (68); y una sonda central (62), una parte de la sonda central dispuesta en el orificio longitudinal, en donde el orificio longitudinal está alineado a lo largo de un eje central de la junta hidraúlica giratoria, en donde la sonda central está configurada para detectar una posición axial de un elemento de pistón (30) dispuesto alrededor de una parte del extremo distal de la sonda central mediante detección inductiva, caracterizada por que la sonda central está fijada a la carcasa de tal manera que el pistón puede moverse axialmente con relación a la parte del extremo distal de la sonda central.
