Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
163 words
An alternative reciprocating compressor having at least a pair of plungers or pistons diametrically opposed and operating in reciprocal fashion comprising a driving shaft which is affixed to a circular eccentric, said circular eccentric being externally enclosed by an enclosing eccentric, both said eccentrics having ball or roller bearings located at their external edges, said enclosing eccentric being contained in a substantially cylindrical case which has at diametrically opposite points extensions to which the plungers are joined, the driving shaft being affixed to said circular eccentric with their respective longitudinal axes spaced, said circular eccentric being disposed in said enclosing eccentric with their respective longitudinal axes spaced, such that rotation in one direction of the driving shaft causes the enclosing eccentric to rotate in alternate directions thereby causing the successive approximation and separation of the longitudinal axes of the enclosing eccentric and the driving shaft within a plane comprising the longitudinal axis of the plungers, which imparts a reciprocating movement to said plungers.
Claim 2
Dependent Claim
163 words
An alternative reciprocating compressor having at least a pair of plungers or pistons diametrically opposed and operating in reciprocal fashion comprising a driving shaft which is affixed to a circular eccentric, said circular eccentric being externally enclosed by an enclosing eccentric, both said eccentrics having ball or roller bearings located at their external edges, said enclosing eccentric being contained in a substantially cylindrical case which has at diametrically opposite points extensions to which the plungers are joined, the driving shaft being affixed to said circular eccentric with their respective longitudinal axes spaced, said circular eccentric being disposed in said enclosing eccentric with their respective longitudinal axes spaced, such that rotation in one direction of the driving shaft causes the enclosing eccentric to rotate in alternate directions thereby causing the successive approximation and separation of the longitudinal axes of the enclosing eccentric and the driving shaft within a plane comprising the longitudinal axis of the plungers, which imparts a reciprocating movement to said plungers.
Claim 3
Dependent Claim
56 words
An alternative reciprocating compressor according to claim 1, wherein the longitudinal axis of the enclosing eccentric moves towards the longitudinal axis of the driving shaft during half a complete revolution of the driving shaft and thereafter moves away therefrom during a second half of a complete revolution, said geometric centers approaching one another without ever overlapping.
Claim 4
Dependent Claim
29 words
An alternative reciprocating compressor according to claim 1, wherein the enclosing eccentric rotates in the same direction as the circular eccentric during half a revolution of the driving shaft.
