Abstract:
A scroll compressor is provided that may include a casing; a drive motor provided at an inner space of the casing; a rotational shaft coupled to a rotor of the drive motor, and rotated together with the rotor; a frame provided below the drive motor; a fixed scroll provided below the frame, and having a fixed wrap; and an orbiting scroll provided between the frame and the fixed scroll, having an orbiting wrap so as to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the fixed wrap. In a state in which a center of the fixed scroll and a center of the orbiting scroll are substantially the same, an interval between the fixed wrap and the orbiting wrap gradually increases towards the suction chamber from the discharge chamber.
