Abstract:
A device for spraying work pieces with an operating fluid, comprising:a) at least one spraying head (58; 222), b) a supplier receptacle (136; 212) for an operating fluid which is to be applied by spraying, c) a feed pump (138; 210) for conveying the operating fluid from the supplier receptacle (136; 212) to the spraying heads (58; 222); d) a device for adjusting the flow of the operating fluid supplied to the spraying heads (58; 222) including (i) a heating device (130; 168; 244 to 260) comprising a heat exchanger (16; 244) fitted into a connecting line which extends between the outlet of the feed pump (138; 210) and the spraying heads (58; 222), wherein the heat exchanger (16) comprises at least two ducts (32, 34, 36) coupled to each other, to, in turn, facilitate thermal conduction between the at least two ducts; and (ii) flow control means selected from the group consisting of an electrical switching valve (128) controlling the open time and closed time of the spraying heads and a pressure control valve (140).
