Abstract

Cet appareil comprend: un ensemble piston-cylindre pneumatique à mouvement alternatif, servant à produire un mouvement primaire puissant activé par une chambre de travail (5) et un mouvement de retour doux activé par une chambre de retour (7), ou un ou plusieurs mouvements secondaires plus doux pas à pas; et une soupape (19) conçue pour permettre différents pas fonctionnels et qui est enfermée dans une extrémité du cylindre (1) et comporte un canal d'admission (18) pour pressuriser la chambre de travail (5), et un canal de dérivation pour vider la chambre de retour (7) en même temps que la chambre de travail (5) est pressurisée, et un canal traversant servant à relier entre elles la chambre de travail (5) et la chambre de retour (7), afin d'égaliser la pression dans ces deux chambres (5, 7), en même temps que le canal d'admission et le canal d'émission sont étranglés par cette soupape, la chambre de retour (7) communiquant avec la soupape au niveau de l'extrémité (19) du cylindre par l'intermédiaire d'un passage (44) s'étendant axialement à travers la paroi du cylindre.
