Abstract
Regulador de presión para respiradores autónomos, que comprende: un cuerpo sustancialmente cilíndrico, cerrado por ambos extremos y dotado en un extremo de un orificio para entrada de gas a alta presión y en el otro extremo poseyendo un orifico para la salida de gas a bajo presión y quedando montado un tabique de partición radial fijo dentro de dicho cuerpo cilíndrico, en las proximidades del extremo del mismo que comunica con dicha abertura de entrada de gas a alta presión y existiendo un tabique radial desplazable axialmente, montado en el interior de dicho cuerpo cilíndrico, cerca del extremo del mismo que comunica con dicha abertura de entrada de gas a alta presión y existiendo un tabique radial desplazable axialmente, montado en el in interior de dicho cuerpo cilíndrico, cerca del extremo del mismo que comunica con dicha abertura de salida de gas a baja presión y que está separado axialmente de dicho tabique fijo, para definir entre ambos, en el interior del mencionado cuerpo cilíndrico, una cámara y existiendo una abertura en dicho cuerpo cilíndrico que pone la mencionada cámara en comunicación con la atmósfera circundante así como orificio centrales alineados axialmente en ambos tabique fijo y móvil y un vástago tubular en el interior de dicho cuerpo cilíndrico guiado por dichos orificios de los mencionados tabiques fijo y móvil, estando guiado dicho vástago con capacidad de deslizamiento con un retén estanco a los gases a través del orificio del tabique fijo y quedando fijado mediante acoplamiento estanco a los gases al orificio de dicho tabique móvil y existiendo un asiento fijo de válvula montado dentro de dicho cuerpo cilíndrico, en su parte central, en el extremo del mismo que comunica con la entrada de gas a alta presión y coopera con el extremo de dicho vástago que pasa a través del orificio existente en el mencionado tabique fijo.
