Abstract

Perfeccionamientos en compresores rotativos, del tipo de cierre por aceite, caracterizados porque se dota a cada compresor de una válvula de seguridad dispuesta para limitar o cerrar la entrada del compresor cuando la presión del compresor se eleva por encima de un valor predeterminado; medios de ventilación sensibles a la subida de presión, en la linea de suministro de aire comprimido, por encima de una valor predeterminado que supera al valor de trabajo normal, y dispuestos para ventilar los espacios de impulsión y compresión del compresor; y una válvula de presión mínima dispuesta para cerrar el conducto de impulsión al objeto de evitar que el flujo de la línea de suministro retorne al espacio de impulsión.
