ABSTRACT:
A cam having a front surface and a rear surface to reciprocate a double-headed piston of a compressor twice for every rotation of a drive shaft. A positioner is provided on the front and rear surface of the cam to position the cam on a fixture used for grinding of cam surfaces. The cam surfaces are formed by grinding the front and rear surface of the cam into a convex shape with the cam positioned to the fixture by the positioner. The front cam surface and the rear cam surface have identical shapes and their phases are offset by a predetermined angle with respect to one another. The positioner is arranged at the same position on the front and rear surfaces of the cam with respect to the cam shape.
