Abstract
The invention discloses a sealing device of a rotation piston type internal-combustion engine. The sealing device comprises the internal-combustion engine, at least a pair of end face construction members and a central construction member, wherein the internal-combustion engine is provided with a rotation piston rotating around an eccentric shaft, a coupling gear and a meshing gear, an oil removal hole is arranged on the at least one pair of end face construction members, the end face construction members surround the rotation piston, at least one axial sealing stripe is arranged on the end face construction members, and an oil removal stripe for assisting the axial sealing stripe is arranged on the at least one pair of end face construction members. The specific oil removal stripe is arranged at the back of the oil removal hole, and the axial sealing stripe achieves height remission due to the fact that a quickening area directly drives engine oil on the rotation piston to a corner. Simultaneously gas sealing and certain oil sealing functions are completely achieved by receiving or restraining oil spilling. The oil removal stripe is relatively simple in structure assembly and low in manufacture cost simultaneously.
