Abstract (en)
[origin: WO2017129489A1] The invention concerns a device (15) for conveying and heating a liquid, intended to be installed between a means for circulating the liquid and a wiper blade of a wiper system, comprising a wall (21) delimiting at least one conduit (22, 23) for circulating the liquid and an electrical circuit intended to connect two terminals set to different potentials and comprising a heating element embedded in said wall (21), characterised in that at least one portion of said electrical circuit is formed by a self-regulating cable (30) arranged to limit a current flowing through the electrical circuit depending on an increase in temperature. Said invention can be used for motor vehicles.
