Piston compressor, especially for coolant compression, has compression piston driven by drive that interacts with expansion piston so work of expansion is used to drive compressor piston

摘要

The piston compressor has at least one compression piston (136) moving within a compression cylinder (142) and driven by a crank drive that interacts with an expansion piston (136) of an expansion part of the compressor so that the work derived from expansion can be at least partly used to drive the compressor piston.
