The present invention relates to a device for automatic closing of cut-off throttle at hose reels including a rotatable reeling or wind-up drum (12) with at least one suction hose (10) for extracting or sucking-out contaminated gases. In order to make this device simple and reliable in operation, a position changing device (32) is mounted on or at the wind-up drum (12) so that said position changing device (32) cooperates with a throttle pivoting means (31) one or two times per revolution of said wind-up drum (12) and so that said position changing device (32) reverses the throttle pivoting means (31) when the direction of rotation of the wind-up drum (12) is reversed.
Dispositif de fermeture automatique de l'étrangleur de coupure dans les tambours à tuyaux comprenant un tambour rotatif de bobinage ou enroulement (12) comportant au moins un tuyau d'aspiration (10) qui extrait ou aspire des gaz contaminés. Afin de simplifier et de rendre plus fiable le fonctionnement de ce dispositif, un dispositif de changement de position (32) est monté sur le tambour d'enroulement (12) ou à proximité de celui-ci, de sorte que ledit dispositif de changement de position (32) coopère avec un élément de pivotement (31) de l'étrangleur une ou deux fois à chaque rotation du tambour (12), et de sorte ce même dispositif de changement de position (32) inverse le mouvement de l'élément de pivotement (31) de l'étrangleur lorsque la direction de rotation du tambour (12) est inversée.
