Abstract

Un dispositivo de inyección para suministrar una composición líquida, que comprende un alojamiento generalmente alargado (2), dispuesto para sostener un cartucho intercambiable (3) que contiene la composición líquida; el alojamiento comprende un dispositivo de impulso y una varilla de émbolo (5) conectada con el dispositivo de impulso y conectada con un émbolo dentro del cartucho, cuando el cartucho se sostiene en el alojamiento, para impulsar el émbolo dentro del cartucho; el émbolo comprende un conector de varilla (7) conectado con una porción de extremo frontal (8) de la varilla de émbolo; el conector de varilla tiene una abertura de entrada definida por secciones de pared del conector de varilla, el ancho de la abertura de entrada es más pequeño que el ancho de la porción de extremo frontal; el ancho de una porción de varilla adyacente a y hacia la parte trasera de la porción de extremo frontal a lo sumo corresponde con el ancho de la abertura de entrada; las secciones de pared son resilientes para habilitar que la porción de extremo frontal pase la abertura de entrada tras ejercer una fuerza de apertura sobre las secciones de pared; el conector de varilla comprende una porción de tope de varilla, en donde existe un juego longitudinal entre la varilla de émbolo por un lado y la abertura de entrada y la porción de tope de varilla por el otro, habilitando por tanto que la porción de extremo frontal se mueva hacia atrás y hacia adelante entre la abertura de entrada y la porción de tope de varilla sin mover el émbolo.
