Beschreibung
Zusammenfassung:	A motion conversion device (200) including a body (310), a first double-acting cylinder (320) movable along a first axis (A4) and a second double-acting cylinder (330) movable along a second axis angled relative to the first axis. The body includes several bores which form a closed circuit and house the first and second double-acting cylinders. Movement of the first double-acting cylinder along the first axis hydraulically or pneumatically pushes the second double-acting cylinder along the second axis. Also disclosed is a valve incorporating a motion conversion device with angled double-acting cylinders for moving a closure member between an open position and a closed position, and a method for opening and closing a valve by way of angled double-acting cylinders. L'invention porte sur un dispositif de conversion de mouvement (200), lequel dispositif comprend un corps (310), un premier cylindre à double action (320) mobile le long d'un premier axe (A4) et un second cylindre à double action (330) mobile le long d'un second axe en angle par rapport au premier axe. Le corps comprend plusieurs trous, qui forment un circuit fermé et qui renferment les premier et second cylindres à double action. Un mouvement du premier cylindre à double action le long du premier axe pousse hydrauliquement ou pneumatiquement le second cylindre à double action le long du second axe. L'invention porte également sur une vanne incorporant le dispositif de conversion de mouvement avec des cylindres à double action en angle pour déplacer un élément de fermeture entre une position ouverte et une position fermée, et sur un procédé pour ouvrir et fermer une vanne à l'aide de cylindres à double action en angle.
