摘要

The machine has a compressor comprising a compression piston (6) which is moved in a compression cylinder. The piston has a crank (12) with a variable length during the rotation of a crankshaft (11) so that the movement of the piston is slowed down during its passage from top dead center and bottom dead center. The crank is formed of crank sections (12a, 12b) which are articulated with each other.
