Abstract

Válvula compensadora de presión para cámaras frigoríficas. Esta válvula comprende dos ventiladores (1 y 2) accionados por sendos motores independientes (1a y 2a) de igual potencia, un circuito eléctrico de control (3), unos leds (4) indicadores del estado operativo de los ventiladores (1 y 2), una resistencia eléctrica (5) para el calefaccionado del conjunto de la válvula, un tubo de canalización (6) del flujo de aire producido por los ventiladores (1 y 2) y dos rejillas extremas (7 y 8). El tubo (6) se encuentra montado en un orificio practicado en una pared (9) de la cámara frigorífica y rematado por las rejillas (7 y 8). Los ventiladores (1 y 2) se encuentran montados, por medio de una carcasa (10) en el interior del tubo (6) proyectando sendos flujos de aire (1b y 2b) hacia el interior y hacia el exterior de la cámara frigorífica respectivamente.
