ABSTRACT:
A rotary type internal combustion engine including a cylindrical rotor having a diametrical slot parallel with the longitudinal axis of the rotor and a vane movably mounted in the vane groove and constituted by two vane parts opposed to each other at the center of the vane in the radial direction thereof. The rotor is rotatably mounted in a housing having an internal chamber with a lower inner wall part with a cross-sectional shape of part of a circle and with which the rotor is coaxially rotatable in close contact therewith, and an upper inner wall part with a cross-sectional shape of part of an approximately elliptical shape and the center of which is offset from the center of the circular cross-sectional shape in a direction away from the lower inner wall part, the approximately elliptical shape having a constant diameter through the center of the circular cross-sectional shape, the vane having a diametrical dimension equal to the constant diameter and the upper inner wall part being at least the part of the entire inner wall which is on the side of the center of the circular cross-sectional shape in the direction of offset of the center of the elliptical shape, the radially outer ends of the vane parts engaging the inner wall of the upper inner wall part in substantially gas tight relation during rotation of the rotor. Vane guide chambers are provided at opposite ends of the internal chamber and have the approximately elliptical cross-sectional shape coaxial with the upper inner wall part of the housing, and vane guide portions on the opposite axial ends of the vane guides engage the inner walls of the vane guide chambers during rotation of the rotor.
