FIELD: manufacture of engines. SUBSTANCE: four members (9a, 9b, 11a, 11b) are articulated together forming deformable parallel link mechanism by means of four parallel axles (A1-A4). Crank 31 sets the first coordination axle (K1) which is connected with one member 9a in circular motion. Other member (11b) is articulated with housing of machine by means of second coordination axle (K2). Chamber having varying volume is formed between cylindrical surfaces (S1-S4) whose axes (C1-C4) intersect longitudinal axes (Da, Db) of the first members (a, 9b). Spool valve holes (19, 21) are opened and closed in turn by members depending on angular position of crank 31. Spark plug 25 is also provided. Each first member (9a, 9b) is provided with two convex cylindrical surfaces (S1, S2, S3, S4) which are rigidly interconnected. Each cylindrical surface is dynamically and tightly connected with cylindrical surface of other member. Invention may be used for designing the four- stroke machines. EFFECT: enhanced efficiency. 43 cl, 26 dwgi |
