AXIAL-PISTON ENGINE Russian patent published in 2011 - IPC F02B75/26 F02B75/04 F02D15/04 

FIELD: engines and pumps.

SUBSTANCE: invention refers to engine building industry, to axial-piston engines of inner combustion with cylinder axes located in the same plane with drive shaft axis and swinging tilting washer. Axial-piston engine includes cylinder blocks of working (1) and compressor (7) chambers, engine shaft (13) with tilting plates (14, 15), camshaft (16), swinging washers (18, 19), supports (24) with levers (25), cylinder head of working chamber (26) with combustion chambers of variable volume (27), cylinder head of compressor chamber (39), intake manifolds (43), compressor (44), fuel pump (45) and back-pressure chambers (47). Cylinder blocks (1 and 7) contain pairs of opposed cylinders (2, 8). Swinging washes (18, 19) are installed one for every pair of cylinders (2, 8) with journals (20, 21.) Combustion chambers of variable volume (27) include back-pressure (28), output (30) and input (31) valves. Input valves (31) have balance chambers (32). Balance chambers (32) are connected to discharge manifolds (33) by channels (34). Compressor chamber cylinder head (39) contains back-pressure valves at the input (41) and air forcing (41). At air forcing (41) the valves are connected by pipelines (42) with back-pressure valves (28) at air intake of combustion chamber (27). The levers (25) swinging in supports (24) are rigidly connected to hinge joints (5, 11). Back-pressure chambers (47) are located in working chamber cylinder head (26) and interconnected via channels (48). The pistons (46) moving inside back-pressure chambers (47) increase combustion chambers' (27) volume and return to initial position at pressure reduction in combustion chambers (27).

EFFECT: reduction of engine components load at power preservation.
