Title (EN) OPERATING DEVICE
(FR) DISPOSITIF D'ACTIONNEMENT
Abstract:
(EN) An operating device capable of opening and closing a valve by operation of any one of operating tools, an operating pedal or an operating lever and allowing operation of the respective operating tools with operating forces suited for the respective operating tools, comprising an inner push rod (9) adapted to move up and down on the basis of operation of a forward operating pedal (5L) and a backward operating pedal (6L), an outer push rod (10) adapted to move up and down on the basis of operation of an operating lever (4L), a moving body (11) adapted to move on the basis of separate movements of these rods, a spool (12) for opening and closing a valve on the basis of movements of the moving body, and first and second springs (15, 13) for biasing the inner push rod and the outer push rod, respectively, so as to apply an operating force on the operating pedals and the operating lever, respectively.
(FR) Dispositif d'actionnement pouvant ouvrir et fermer une soupape par actionnement d'un outil de commande, pédale ou levier, et actionner lesdits outils par des forces d'actionnement appropriées. Le dispositif comprend une tige poussoir interne (9), conçue pour monter et descendre sur la base de l'actionnement d'une pédale de commande de marche avant (5L) et d'une pédale de commande de marche arrière (6L); une tige poussoir externe (10), conçue pour monter et descendre sur la base de l'actionnement d'un levier de commande (4L); un corps mobile (11), conçu pour se déplacer sur la base de mouvements distincts desdites tiges poussoirs; un tiroir (12), conçu pour ouvrir et fermer une soupape sur la base des mouvements du corps mobile; et un premier et un second ressort (15, 13), conçus pour solliciter respectivement la tige poussoir interne et la tige poussoir externe, de façon à appliquer une force d'actionnement respectivement sur les pédales de commande et sur le levier de commande.
