Abstract (en)
[origin: CA3170298A1] Proposed is a coating device (1) for applying a coating agent to the surface of a workpiece (4). The coating device (1) includes a machine frame (2) having a workpiece receptacle (3), a coating agent source (8, 9) as well as a compressed air source (5). The coating device (1) furthermore includes a rotary unit (12) which is rotatable in relation to the machine frame (2) and has a pump (17) and a plurality of spray units (20), the pump (17) on the suction side being connected to the coating agent source (8, 9) by way of a fluid-conducting rotary joint connection (13), and on the pressure side being connected to the spray units (20). It is essential that the rotary unit (12) has a pneumatic valve device (18), furthermore that the spray units (20) have in each case one compressed air controlled valve (21) for controlling the delivery of coating agent, wherein the valve device (18) on the inlet side is connected to the compressed air source (5) by a fluid-conducting rotary feedthrough (14), preferably a single-channel rotary feedthrough, and on the exhaust air side is connected to the compressed air controlled valves (21) of the spray units (20).
