Abstract
A rotary compressor includes a casing (1), a cylinder block (2), a rotor (3), a sliding plate (4), and a discharge valve (7). A suction port (6) and a discharge port (8) are provided on the casing (1). A rotating center axis of the cylinder block (2) deflects from a rotating center axis of the rotor (3), so that an outer circumference surface of the rotor (3) is inscribed with an inner circumference surface of the cylinder block (2). A head portion of the sliding plate (4) is embedded in a cylindrical body of the cylinder block (2), and a main body of the sliding plate (4) extends into a sliding plate slot of the rotor (3). The discharge valve (7) is provided on the outer circumference of the rotor (3) in front of a rotating direction of the sliding plate (4). A cylinder block inlet (12) is provided on the cylinder block (2) in rear of the rotating direction of the sliding plate (4). The sliding plate (4) and the inscribed point separate a crescent working volume between the inner circumference surface of the cylinder block (2) and the outer circumference surface of the rotor (3) into a suction chamber and a discharge chamber.
