A system for the conversion of a rectilinear swaying motion into a rotating motion and vice versa, with an inlet/outlet of lineal motion through pistons (212, 213;
- 412, 413) and a turning outlet/inlet comprised of shafts (AP2;
- AP4) and pinions (P2;
- P4), comprising:
- a hollow cylinder (22;
- 42) lineally moveable in a side surface of which are provided blind grooves (23;
- 43) having a closed zigzag formed with a plurality of rounded peaks (23a;
- 43a) and valleys (23b;
- 43b) and straight portions (23c;
- 43c), displaced from each other so that each pair of homologous points (H1, H2) are located in the same line parallel to the axis (22a;
- 42a), with the points of inflection of the lines that form the external edges of the external rounded sections at the same distance (D) of the respective ends of the grooved cylinder (22;
- 42), where the pistons are positioned (212, 213;
- 412, 413);
- two rotating revolution pieces each substantially shaped as a crown (25a, 25b;
- 45a, 45b) to coaxially accommodate the grooved cylinder (22;
- 42), each rotating piece having a trunk-conical end piece (26-26;
- 46-46) and rings (27;
- 47a-47b), connected to each other, wherein the inner wall of the rotating pieces (25a, 25b;
- 45a, 45b) includes a connection area between the end pieces (26-26;
- 46-46) and the rings (27-27;
- 47a-47b), and a plurality of housings (28;
- 48) complementary to the grooves in zigzag (23;
- 43), each end piece (26-26;
- 46-46) having an indentation (26a-26b;
- 46a-46b);
- and wherein on a surface of external bases of the end pieces (26-26;
- 46-46) are circular grooves (229-229;
- 429-429) concentric to an axis of the hollow cylinder (22a;
- 42a);
- a pair of guide cylinders (210, 211;
- 410, 411) in which the respective pistons (212, 213;
- 412, 413) of the ends of the grooved cylinder (22;
- 42) move whereby providing the inlet/outlet of lineal motion;
- a crankcase (214;
- 414) for the assembly of the grooved cylinder, the revolution pieces, and the guide cylinders, including crankcase covers (214a, 214b;
- 414a, 414b), in the inner base of the crankcase is a circular groove (232 232;
- 432 432) concentric to the axis (22a;
- 42a) that serves with the circular groove (229-229;
- 429-429) of the external bases of the respective piece of trunk-conical end (26-26;
- 46-46) to fittingly house a first bearings crown (233-233;
- 433-433) that allows the turn of the respective revolution piece (25a, 25b;
- 45a, 45b) in relation to the respective crankcase cover (214a, 214b;
- 414a, 414b);
- bearings sets (B12;
- B14) mounted between the grooves (23;
- 43) of the grooved cylinder (22;
- 42) and the complementary housings (28;
- 48) of the rotating pieces of revolution (25a, 25b;
- 45a, 45b);
- a second bearings crown (231;
- 431), fittingly displaced between circular grooves (230 230;
- 430-430) concentric to the axis (22a;
- 42a) correspondingly provided in the opposite faces of the rings (27 27;
- 47a 47b) to allow turning the rotating pieces of revolution (25a, 25b;
- 45a, 45b) in opposite directions;
- and
- a pair of trunk-conical pinions (P2, P4) that gear in the indentation (26a-26b;
- 46a-46b) of the corresponding end piece (26-26;
- 46-46) having shafts (AP2, AP4) that comprise the rotating exit/entry of the system (21,41) and that are mounted on the crankcase (214;
- 414).
