Abstract

Perfeccionamientos en dispositivos de mando para la inyección de aceite en un compresor helicoidal con una válvula de parada del aceite incorporada en la tubería de inyección, cuya pieza de cierre está gobernada a través de un vástago de válvula y una membrana que actúa sobre éste en dependencia de la presión de impulsión del compresor helicoidal, caracterizados porque el vástago de válvula de la válvula de parada del aceite, en su zona conducida fuera de la carcasa de válvula en forma hermetizada, posee una sección que corresponde como mínimo en igual escala a la superficie de hermetización eficaz de la pieza de cierre y porque en el vástago de la válvula se ha previsto un canal longitudinal que conduce desde la zona de la superficie de hermetización hacia el recinto de presión de cierre de la membrana, desembocando en el recinto de presión de abertura de la membrana una tubería de mando unida con la tubería de impulsión del compresor helicoidal.
