Abstract

El impulsor 81) acorde con la invencion presenta una placa presionada (4) sustentada en forma desplazable en una guía (11), que limita una camaracompensadora (2). La placa presionada (4) se desplaza como concecuencia de una diferencia entre la presion circundante y la presion interna de la cámaracompensadora(2) y habilita una línea presurizada (18) a través de una union forzada con un elemento de cierre (22), de modo de poder comandar una válvula(42) conectada a continuacion en forma pasiva, es decir, sin impulsos de comando adicionales.The impeller 81) according to the invention has a pressed plate (4) supported in a movable way in a guide (11), which limits a compensating chamber (2). The pressed plate (4) moves as a consequence of a difference between the surrounding pressure and the internal pressure of the compensating chamber (2) and enables a pressurized line (18) through a forced union with a closing element (22), in order to be able to command a valve (42) subsequently connected passively, that is, without additional command pulses.
