Abstract

Una válvula de estrangulacion de una máquina es colocada de manera controlada por un motor eléctrico que está acoplado a la válvula de estrangulacion a través del primer y segundo engranajes espirales de radio variable unidos. El motor trabaja contra la fuerza de un resorte de regreso de la válvula de estrangulacion, y está fuerza aumenta conforme la válvula de estrangulacion es llevada lejos de una posicion de fallo de seguridad. Al elegir la variacion de la velocidad de los radios de los engranajes espirales para coincidir con la variacion de la fuerza ejecutada por el resorte con la posicion de la válvula de estrangulacion, un momento de torsion de accionamiento constante producida por el motor sobrepasará el momento de torsion en aumento producido por el resorte.
