Abstract

Un actuador (1) para una válvula piloto (26), que incluye una carcasa (2), un pistón (4) montado de forma móvil en la carcasa (2) y una cámara del actuador (20) definida entre el pistón (4) y la carcasa (2). El actuador (1) incluye una alimentación de fluido de control (16) para introducir un fluido en la cámara del actuador (20) para controlar la presión del fluido, con la presión del fluido que actúa sobre el pistón (4). El actuador (1) también incluye un miembro de accionamiento para actuar sobre la válvula piloto (26) y un resorte de carga (6) entre el pistón (4) y el miembro de accionamiento. El resorte de carga (6) se dispone para empujar el pistón (4) contra la presión del fluido en la cámara del actuador (20). La alimentación de fluido de control (16) controla la presión del fluido de manera que la presión del fluido actúa sobre el pistón (4) contra el empuje del resorte de carga (6) para controlar la fuerza de desviación.
