Abstract

Un tornillo de avance, una tuerca (7) de avance y un miembro de impulso (8) se alinean con un eje que define un sentido axial y un sentido axial opuesto. Un acoplamiento entre el tornillo de avance y la tuerca de tornillo de avance permite un movimiento helicoidal del tornillo de avance con respecto a la tuerca de tornillo de avance por lo menos en el sentido axial. El tornillo de avance se acopla con el miembro de impulso, el acoplamiento genera un movimiento helicoidal del tornillo de avance con respecto al miembro de impulso cuando el miembro de impulso se mueve en el sentido axial con respecto al tornillo de avance. Una característica (19) de detención de dispensación de la tuerca de tornillo de avance y una característica (20) de detención de dispensación del miembro de impulso evitan la generación del movimiento helicoidal del tornillo de avance cuando se aproxima una posición final específica del miembro de impulso.
