Abstract

La invención se relaciona con un dispositivo de inyección accionado por resorte de torsión que tiene un mecanismo de selección descendente para seleccionar descendentemente un tamaño de dosis seleccionado. El resorte de torsión está tenso cuando se establece una dosis al girar un botón de ajuste de dosis situado proximalmente (30) en relación con la carcasa en una primera dirección y sin tensar cuando se gira el mismo botón de ajuste de dosis (30) en una 10 segunda dirección opuesta a la primera dirección. Con el fin de asegurar al resorte de torsión (2) en su posición tensa se proporciona un mecanismo de trinquete de una vía. Este mecanismo de trinquete de una vía comprende un elemento de fijación (1) acoplado a la carcasa y cuenta con un dentado (6) y un elemento de trinquete (20) que tiene por lo menos un brazo de trinquete (22) que acopla el elemento de fijación (1) y cuyo elemento de trinquete (20) es acoplado operacionalmente con el botón de ajuste de dosis (30). El botón de ajuste de dosis (30) acopla directamente por lo menos un brazo de trinquete (22) cuando el botón de ajuste de dosis (30) se gira en la se9unda dirección lo cual libera el por lo menos un brazo de trinquete (22) del dentado (6) del elemento de fijación (1) y permite que el elemento de trinquete (20) gire en relación con el elemento de fijación (1) en la segunda dirección bajo la influencia del resorte de torsión (2).
