Abstract

Un compresor rotativo (1) que comprende: al menos un cilindro (410) instalado en un espacio interior de un recipiente hermético (100), que tiene un espacio (V2) de compresión para comprimir un refrigerante, y dotado de una cámara (413) de paleta aislada en el interior del espacio interior del recipiente hermético (100); una pluralidad de cojinetes (120, 130) conectados a los lados superior e inferior del cilindro (410) para cubrir el espacio de compresión del cilindro (410) y la cámara (413) de paleta; al menos un émbolo giratorio (420) configurado para comprimir el refrigerante orbitando en el espacio (V2) de compresión del cilindro (410); al menos una paleta (430) conectada de forma deslizable al cilindro (410) y configurada para dividir el espacio (V2) de compresión en una cámara de succión y en una cámara de descarga en cooperación con el émbolo giratorio (420), estando soportada al menos una de las mismas por un refrigerante que llena la cámara (413) de paleta del cilindro (410); y una unidad (500) de cambio de modo configurada para modificar el modo de funcionamiento del compresor (1) suministrando de forma selectiva un refrigerante de presión de succión o un refrigerante de presión de descarga a la cámara (413) de paleta del cilindro (410), estando dotado el cilindro (410) de un orificio (416) de conexión para permitir la comunicación de la cámara (413) de paleta con la unidad (500) de cambio de modo introduciendo un tubo (531) de conexión en el orificio (416) de conexión para permitir la conexión del conducto (530) de conexión de la unidad (500) de cambio de modo, estando el compresor rotativo caracterizado por que la cámara (413) de paleta del cilindro (410) está dotada de un saliente (417) de conexión que sobresale desde una superficie circunferencial de la misma para su escalonamiento, y por que la curvatura de un extremo del saliente (417) de conexión es más pequeña que la curvatura de la superficie circunferencial interior de la cámara (413) de paleta, de modo que el refrigerante suministrado al interior de la cámara (413) de paleta se concentra hacia la paleta (430).
