摘要：
A swash plate compressor includes a cylinder block having therein several cylinder bores and a crank chamber. A drive shaft is rotatably supported in the cylinder block. Each of several pistons is slidably disposed within one of the cylinder bores. A swash plate is disposed in the crank chamber and is tiltably secured to the drive shaft. A bearing couples the swash plate to each of the pistons, so that the pistons are driven in a reciprocating motion within the cylinder bores. Several stepped, chamferred portions are formed in succession on an opening edge of each of the cylinder bores. The structure for the swash plate compressor according to this invention reduce or eliminates damage of the outer surface of pistons without increasing the weight of the swash plate compressor.
