An alternative reciprocating compressor having a driving shaft that is solidly fastened to a circular eccentric which externally, and by means of a ball or roller bearing is enclosed by another eccentric which is also circular and is also provided at its external rim with a ball or roller bearing. The other eccentric at its outer path incorporates, at diametrically opposite points extensions to which plungers are joined, in such a way that the turn of a driving shaft originates alternate rotating slidings of one eccentric with respect to the other thus causing the successive approximation and separation of the geometrical axes pertaining to the enclosing eccentric and the driving shaft within a plane comprising the longitudinal axes of the plungers, which is converted in the claims.
