<p>Disclosed is a rotary compressor which includes a housing (10) having a disc wall (16) and a semi-spherical wall (18), an inlet port (20) and an outlet port (22) provided on the disc wall (16), a rotor (12) comprising a conical portion (30) slidably engaging the disc wall (16) at a position between the inlet port (20) and outlet port (22) and a partial spherical portion (32) provided on the bottom of the conical portion (30), and a semicircular vane (14) slidably inserted into an expanding slot (40) defined in the rotor (12) and extending through the center line (12a) of the rotor (12). Since the conical portion (30) of the rotor (12) is rotated and the disc wall (16) of the housing (10) is fixed, a rotation prevention mechanism, which is required in a conventional rotary compressor, is not necessary. Therefore, the structure of the rotary compressor is simplified and the number of parts is small. A miniaturized and light-weight rotary compressor can be manufactured inexpensively. <IMAGE></p> |
