Abstract

Circuito de control para una válvula automática accionada por motor que comprende medios de relé que tienen contactos para controlar la conexión del motor para determinar la dirección de marcha del mismo, un circuito de conmutación electrónica conectado en serie con el motor a través de dichos contactos, medios de polarización para polarizar dicho circuito de conmutación electrónica a un estado conductor y medios limitadores sensibles a la corriente del motor para conmutar dichos medios de conmutación electrónica a un estado no conductor cuando la corriente del motor rebasa un nivel predeterminado, incluyendo dichos medios de limitación un circuito de enclavamiento electrónico para mantener a dichos medios de conmutación electrónica en estado no conductor una vez que dicha corriente del motor ha rebasado dicho nivel predeterminado.
