Abstract

Interruptor de control accionado por presión fluida, sensible a dos presiones flúidas independientes y normalmente iguales para controlar un circuito de control eléctrico de un dispositivo avisador siempre que la diferencia entre dichas presiones flúidas sea superior a un valor predeterminado, siendo dicho interruptor de control del tipo que comprende, en un alojamiento, un pistón herméticamente deslizable en un taladro de dicho alojamiento que define en él dos cámaras de flúido opuestas adaptadas para suministrarse respectivamente con las dos presiones flúidas citadas; medios elásticos que se oponen al desplazamiento de dicho pistón respecto a una posición centrada normal y un miembro de contacto interruptor desplazable funcionalmente accionado por dicho pistón para impulsarlo desde una posición de reposo a otra activada, al objeto de acoplar eléctricamente a un miembro de contacto interruptor relativamente fijo siempre que dicho pistón es alejado de su posición normal citada por la presión diferencial que actúa sobre él, contra la fuerza de retorno de dichos medios elásticos, caracterizado porque comprende medios fiadores capaces de acoplarse al citado miembro de contacto interruptor desplazable en dicha posición activada, y medios liberadores accionables desde el exterior y funcionalmente conectados a dicho miembro de contacto interruptor desplazable.
