Abstract:
A mechanism for transforming rotating into reciprocating motion, or vice versa, comprising first and second annular components (1, 3) located coaxially along a longitudinal axis (ΔA). The first and second annular components are both able to rotate around and reciprocate along the longitudinal axis. A side (A) of the first annular component (1) is in continuous contact, in at least one point, with a neighboring side (Γα) of the second annular component (3) so that the second annular component (3) is able to rotate relative to and in continuous contact with at least one point with the adjacent side (A). The contacting sides are undulated surfaces (A, Γα) such that if the first and second annular components are forced into rotational motion, they remain in continuous contact so that every point of the undulated surfaces will trace, relative to the other, an undulated trajectory and also execute reciprocating motion.
