A high thrust drive system usable in a variety of devices, e.g., fluid dispensing, article clamping, article lifting and article jacking, includes a driving rod member, an actuating member movable through a driving stroke and a return stroke, and a gripping plate having a passage therein through which the driving rod extends for gripping the driving rod and moving the rod in a thrust-applying direction during the driving stroke of the actuating member. The actuating member imposes a high thrust on the driving member through the gripping plate during the driving stroke, and the gripping plate imposes a torque on the driving rod in a first rotational direction as the actuating member is moved through the driving stroke. A recoil plate is oriented to grip the driving rod during the return stroke of the actuating member and impose a torque on the driving rod in the same first rotational direction as the gripping plate to precule movement of the driving rod in a direction opposite the thrust-applying direction, whereby applying a torque on the driving rod in the same rotational direction during the driving and return strokes of the actuating membrer imparts a smooth, linear motion to the driving rod as the driving rod is moved in the thrust-applying direction.
ystème de transmission de mouvement pouvant être utilisé dans diverses applications, p.ex. distribution de liquide, préhension d'objets, levage d'objets, etc., et constitué d'une tige de commande, d'un actionneur animé d'un mouvement de va-et-vient et d'une plaque de préhension à travers laquelle passe la tige de commande et qui sert à saisir la tige de commande et à l'entraîner dans sa course. Lors du mouvement d'aller, l'actionneur imprime une forte poussée à la tige de commande par l'intermédiaire de la plaque de préhension, qui oppose à la tige un couple de rotation dans un sens déterminé. Une deuxième plaque, orientée pour saisir la tige de commande lors du mouvement de retour, oppose à cette dernière un couple de rotation dans le même sens que la plaque de préhension, de manière à empêcher le mouvement de la tige dans le sens contraire au sens d'application de l'effort. L'application à la tige de commande d'un couple de rotation dans le même sens à l'aller et au retour de la course de l'actionneur permet d'imprimer à la tige un mouvement linéaire régulier
