Abstract

La presente invencion se refiere a un aparato para controlar la operacion de un actuador neumático y un actuador neumático que tiene dicho mecanismo de control. Más particularmente, el aparato de control del actuador de la presente invencion incluye una cubierta montada a un recubrimiento angosto del extremo del actuador, una válvula solenoide colocada dentro de la cubierta y una válvula de control de gas que controla el gas presurizado admitido y descargado del actuador por la operacion de la válvula. La válvula de control de gas actua en respuesta a la válvula solenoide y está montada a la cubierta. Preferentemente, el aparato de control incluye un mecanismo de indicacion de posicion, colocado dentro de la cubierta, el cual determina una posicion previamente especificada de la válvula en respuesta al movimiento de por lo menos uno y preferentemente, dos probadores del actuador movibles que se extienden desde el recubrimiento angosto del extremo del actuador hasta adentro de la cubierta. La válvula de control de gas es una válvula de carrete que es controlada neumáticamente por la válvula solenoide. El mecanismo de indicacion de posicion incluye un interruptor de mecanismo o un interruptor inductor de proximidad, determinando cada uno de dichos probadores del actuador la posicion de un extremo de cada probador del actuador que son operados cada uno por un extremo del probador del actuador conforme se mueve dentro de la cubierta, en respuesta al movimiento del actuador.
