A rotary-piston internal combustion engine (E1) has an output shaft (1); a rotor (2); a housing (4); an annular operation chamber (5) that is formed by the rotor and the housing, on at least one side of the rotor in the direction of the axis of the output shaft, the annular operation chamber (5) forming an intake operation chamber, a compression operation chamber, a combustion operation chamber, and an exhaust operation chamber; a single pressure applying/pressure receiving member (6) that is provided on the rotor and partitions the annular operation chamber; two operation-chamber partitioning members (7, 8) provided on the housing and partition the annular operation chamber; urging mechanisms that individually urge the operation-chamber partition members toward their advanced positions; an intake port (11); an exhaust port (12); and a fuel injector (14). The pressure applying/pressure receiving member (6) is constructed from a circular arc-shaped partitioning member having first and second slope surfaces. The operation-chamber partitioning members (7, 8) are each constructed from a reciprocating partitioning member that advances and retreats in the direction in parallel with the axis of the output shaft. |
