Abstract

EL PRESENTE INVENTO PROPORCIONA UN COMPRESOR DE TORNILLO QUE TIENE UN AMPLIO MARGEN DE FUNCIONAMIENTO RESPECTO A LA TASA DE FLUJO Y LA PROPORCION DE PRESION, QUE VA PROVISTO DE UNA PARTE DE ABERTURA DE DESCARGA (9) DE UNA PIEZA ENVOLVENTE (7) CON UNA PARTE DE MUESCA GENERALMENTE CORTADA DE FORMA CONICA (8) PARA QUE SE DESCARGUE EL GAS COMPRIMIDO GRADUALMENTE DESDE CIERTO PUNTO FIJO DONDE UNA PROPORCION DE VOLUMEN DE UNA RANURA DEFINIDA POR LOS ROTORES (6, 6'') Y LA PARTE ENVOLVENTE (7) ES MENOR QUE UNA PROPORCION DE VOLUMEN INCORPORADA CORRESPONDIENTE. DADO QUE EL PRESENTE INVENTO SE DISPONE EN EL MODO ANTERIORMENTE MENCIONADO, SE REDUCE EL FLUJO RAPIDO DEL GAS EN LA PARTE DE ABERTURA DE DESCARGA POR MEDIO DE LA PIEZA DE MUESCA (8) DE LA PARTE DE ABERTURA DE DESCARGA (9) QUE SE FORMA FACILMENTE, POR MEDIO DE LO CUAL SE DISMINUYE EL MARGEN DE VARIACION DE LA PRESION (LA AMPLITUD DE PULSACION DE LA PRESION) Y BAJA EL NIVEL DE RUIDO. ADEMAS, SE LIMITA LA PERDIDA DE PRESION QUE RESULTA DE UNFLUJO RAPIDO DEL GAS, AMPLIANDO CON ELLO EL INTERVALO DE RENDIMIENTO PREFERIBLE DEL COMPRESOR.
