Abstract
The invention relates to a compressor having a piston and rod assembly which is segmented to allow adjustment of the compressor's output. In particular, fasteners accessible from the top surface of the piston can be removed so that shims can be added or removed from piston rod. The addition or removal of shims lengthens or shortens the piston rod so that the compression ration can be fine tuned. These adjustments, as well as replacement of the piston seal, can be accomplished without extensive disassembly of the compressor.
