Abstract:
An apparatus for coating a compressor piston, comprising:rotation support means for rotatably supporting both ends of a piston for a fixed displacement swash plate type compressor; a pair of first coating material applying means installed above the rotation support means in a manner such that said pair of first coating material applying means can be moved upward and downward, the pair of first coating material applying means having a pair of first nozzles, respectively, which apply coating material to circumferential outer surfaces of both head parts of the piston rotated by the rotation support means, and at the same time spread of a uniform film thickness applied coating material and thereby remove excess coating material, in a state where the pair of first nozzles are placed adjacent to the circumferential outer surfaces of both head parts of the piston; fixing means installed in the vicinity of the rotation support means to fixedly support both ends of the piston; and second coating material applying means installed above the fixing means in a manner such that said second coating material applying means can be moved upward and downward and slid laterally, the second coating material applying means having a second nozzle which applies coating material to a bridge part of the piston fixedly supported by the fixing means, and at the same time is slid to spread to a uniform film thickness applied coating material and thereby remove excess coating material, in a state where the second nozzle is placed adjacent to the bridge part of the piston.
