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 constituted by shafts (AP2;
- AP4) of gears or pinions (P2;
- P4), comprising:
- a hollow cylinder (22;
- 42) lineally moveable, suitably lightened, in the side surface of which are provided blind grooves (23;
- 43) with a development in a closed zigzag or with a great number of rounded peaks (23a;
- 43a) and valleys (23b;
- 43b) and straight portions (23c;
- 43c), displaced separated from each other so that each pair of homologous points (H1, H2) of these 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 foreseen (212, 213;
- 412, 413);
- two rotating revolution pieces in crown form (25a, 25b;
- 45a, 45b) to coaxially accommodate in its inside the grooved cylinder (22;
- 42), each one having a trunk-conical end piece (26-26;
- 46-46) and some ring/s (27;
- 47a-47b), connected to each other to form a whole by means of assembly screws (T2;
- T4-T4), wherein in the inner wall of these rotating pieces (25a, 25b;
- 45a, 45b), in the connection area between the end pieces (26-26;
- 46-46) and the rings (27-27;
- 47a-47b), provided in a circumference with the same angular separation are a group of housings (28;
- 48) complementary to the mentioned grooves in zigzag (23;
- 43), anticipating in each end piece (26-26;
- 46-46) an indentation (26a-26b;
- 46a-46b) of an indented crown;
- and where additionally on the surface of the external bases of the mentioned end pieces (26-26;
- 46-46) are foreseen some circular grooves (229-229;
- 429-429) concentric to the axis of the hollow cylinder (22a;
- 42a);
- a pair of guide cylinders (210, 211;
- 410, 411) lineally opposing inside of which the respective pistons (212, 213;
- 412, 413) of the ends of the grooved cylinder (22;
- 42) move and that constitute the inlet/outlet of lineal motion;
- a crankcase (214;
- 414) for the assembly of the set of grooved cylinder/revolution pieces/guide cylinders, with crankcase covers (214a, 214b;
- 414a, 414b), in the inner base of each one is foreseen 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 bearings crown (233-233;
- 433-433) that allows the turn of the respective revolution piece (25a, 25b;
- 45a, 45b) regarding 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);
- an additional 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) whose shafts (AP2, AP4) constitute the rotating exit/entry of the system (21,41) and that are mounted on the crankcase (214;
- 414) in a well-known form.
