ABSTRACT:
A rotating type intake and discharge apparatus comprises an annular rotary cylinder which is provided with a plurality of cylinder slits formed at its inner circumferential portion in the radial direction and is disposed in a housing so as to be rotatable on a first imaginary cycle, a rotary piston rotatably supported in and by the housing, which comprises piston rollers in the number one-half of that of the cylinder slits, which are arranged on a second imaginary circle having a diameter one-half as large as the first imaginary circle and in internally contact with the same and a center roller disposed near the piston rollers, the piston rollers being capable of revolving on the second imaginary circle; a flow path wall formed by a part of the housing so as to have a side plane which has the same common center as the first imaginary circle and extends along the inner side of the locus of rotation of the rotary cylinder, and a side plane which has the same common center as the second imaginary circle and extends along the outer side of the locus of rotation of the rotary piston; and a pair of intake and discharge ports formed in the housing.
