Wave cam type compressor
 A wave cam type compressor includes cylinder blocks. A drive shaft is rotatably supported in the center cylinder blocks. A plurality of cylinder bores are defined about the drive shaft in the cylinder blocks. A wave cam, mounted on the drive shaft, comprises opposing cam surfaces. A width of second portions which move a piston to its bottom dead center position is more narrow than a width of first portions which move a piston to its top dead center position. The pistons are connected to the wave cam by way of shoes. The shoes move along a predetermined path on the cam surfaces. The shoes and the wave cam convert the integral rotation of the drive shaft and wave cam to a reciprocating movement of the pistons to compress fluid introduced into the cylinder bores.
