Control device for a paint feed circuit in a road marking machine (1), including at least one paint spray gun (2) mounted on a support chassis (11) that can be moved along a paved surface (10) over a line to be marked, and connected to a paint feed circuit (3) with an activation device (21) for paint application. With this invention, the machine is fitted with an alternate command device for opening and closing a feed circuit, including a floating lever (5) mounted so as to pivot on the chassis (1) and fitted with a method (52) for starting the activation device (21). The lever (5) is pivoted by means of a flexible line on a pulley (61) that can be turned by a motor (62) so as either to roll up the flexible line (63) that pivots the lever (5), so as to open the circuit, or to unroll the line to close the circuit (3). The said pulley (61) is linked to a moveable locking mechanism (73) in the open position, so that the activation device (21) can be held open without the motor being turned on.

Dispositif de commande d'un circuit d'alimentation en peinture dans une machine (1) de marquage routier comprenant au moins un pistolet (2) de pulvérisation de peinture monté sur un châssis de support (11) déplaçable sur une chaussée (10) le long d'une ligne à marquer et relié à un circuit (3) d'alimentation en peinture muni d'un organe dedéclenchement (21) de l'application de la peinture. Selon l'invention, la machine est munie d'un dispositif de commande alternative de l'ouverture et de la fermeture du circuit d'alimentation comprenant un levier mobile (5) monté pivotant sur le châssis (1) et portant un moyen (52) d'actionnement de l'organe de déclenchement (21), le pivotement du levier (5) étant commandé par un lien souple s'enroulant sur une poulie (61) susceptible d'être entraînée en rotation par un moteur (62), alternativement dans un sens d'enroulement du lien souple (63) déterminant le pivotement du levier (5) dans le sens d'ouverture du circuit (3) et dans le sens de déroulement pour la fermeture du circuit (3), ladite poulie (61) étant associée à un moyen (73) de verrouillage amovible, au moins dans la position d'ouverture du circuit (3), permettant le maintien de l'organe de déclenchement (21) dans la position d'ouverture sans action du moteur.
