Abstract
A method and a system for applying a highly viscous fluid to an inner surface of a cavity of a tire, comprising an applicator device for the highly viscous fluid and a delivery circuit for the highly viscous fluid connected to the applicator device and having a highly viscous fluid collection device comprising a tank that internally defines a collection chamber; a delivery device for the highly viscous fluid implemented by means of a pumping device that delivers the highly viscous fluid to the applicator device; a movable piston that delimits the collection chamber at the perimeter; an extractor element intended to move with an alternating movement so as to draw the first highly viscous fluid inside the collection chamber and deliver it to the pumping device; and a position sensor, in particular a linear position transducer, suitable for detecting the position of the piston.
