<p>Four elements (9a, 9b, 11a, 11b) are mutually articulated as a parallelogram deformable according to four parallel axes (A1, ...A4). A crank (31) causes a circular motion of a first coordination axis (K1) connected to one (9a) of the elements. Another element (11b) is articulated to the frame along a second coordination axis (K2). A variable volume chamber (17) is defined between the cylindrical surfaces (S1, ...S4) whose axes (C1, ...C4) intersect the longitudinal axes (Da, Db) of the first elements (9a, 9b). Distribution orifices (19, 21) are selectively open and obturated by the elements as a function of the angular position of the crank (31). A sparking-plug (25) is provided. Each first element (9a, 9b) carries two cylindrical convex surfaces (S1, S2; S3, S4) rigidely interconnected. Each cylindrical surface is in dynamic sealing relationship with a cylindrical surface belonging to the other element and whose axis (C1, ...C4) instersects a same line (L14, L23) parallel to the longitudinal directions( Ea, Eb) of the second elements (11a, 11b). Utilization easily constructing a rapid machine of the type four-stroke one-cycle per revolution and low relative speed of the dynamic sealing lines.</p> |
