IMPROVED SPRAYING DEVICE FOR WASHING LIQUID AND WIPER BEARING SAME

摘要

The invention concerns a device (20) for spraying washing liquid on a motor vehicle glass pane comprising a case (22) wherein is arranged a spray chamber (28) supplied with pressurised washing liquid by a conduit (32) whereof the downstream end (34) is connected to an inlet conduit (38) of the spray chamber (28), the latter comprising at least an outlet (30) for spraying the liquid, comprising a non-return valve (46) arranged upstream of the spraying orifices, and comprising a heating wire (48, 50). The invention is characterised in that a heating wire (48, 50) extends longitudinally through the supply conduit (32) and whereof the free end section (50) extends into the spray chamber (28); said heating wire passes sealingly through a passage (52) of the spraying device (20) which extends parallel to the non-return valve (46).
