Embodiment Construction
[0023] The rolling rotor compressor includes: a shell, a cylinder, an eccentric rotor and a sliding vane. The cylinder is placed in the shell, and the eccentric rotor is placed in the cylinder. The centerline of the eccentric rotor and the centerline of the cylinder are parallel to each other. The surface is close to the inner surface of the cylinder; a crescent-shaped space is formed between the outer surface of the eccentric rotor and the inner surface of the cylinder, and its position changes with the rotation angle of the rotor; the reciprocating slide divides the space into two independent Part: high-pressure chamber and low-pressure chamber; the rolling rotor compressor is provided with a suction port, and the suction port is a through hole penetrating through the shell and the cylinder wall; wherein, the center line of the suction port is in line with the cylinder The centers are separated by a distance L.

The invention provides a rolling rotor compressor, which can be used for reducing loss on suction resistance of a cylinder to further improve refrigerating capacity and efficiency of the compressor and simultaneously improving the impact influence of gas just sucked into the cylinder on an eccentric rotor to further improve the efficiency of the compressor. The rolling rotor compressor comprises a casing, the cylinder, the eccentric rotor and a slip sheet, wherein the cylinder is installed in the casing, the eccentric rotor is installed in the cylinder, the center line of the eccentric rotor is parallel to that of the cylinder, and the outer surface of the eccentric rotor is appressed to the inner surface of the cylinder; a crescent space is formed between the outer surface of the eccentric rotor and the inner surface of the cylinder, and the position of the crescent space changes with a rotor angle of the rotor; the space is divided into two independent parts, i.e. a high-pressure cavity and a low-pressure cavity, by the slip sheet moving in a reciprocating mode; and the rolling rotor compressor is provided with an air suction inlet, wherein the air suction inlet is a through hole penetrating through the casing and the wall of the cylinder, and a certain distance L is kept between the center line of the air suction inlet and the center of the cylinder.
Description
technical field [0001] The invention belongs to the technical field of compressors, in particular to a rolling rotor compressor, in particular to a circumferential offset structure of a suction port of a rolling rotor compressor. Background technique [0002] The rolling rotor compressor is a positive displacement compressor, which is mainly composed of a cylinder, an eccentric rotor, a sliding vane, and an exhaust valve. The eccentric rotor is placed in the cylinder, and when the rotor rotates around the center of rotation, the rotor slides against the inner surface of the cylinder. Thus, a crescent-shaped space can be formed between the outer surface of the rotor and the inner surface of the cylinder, and its position changes with the rotation angle of the rotor. The reciprocating sliding plate divides the space range into two independent parts, one part communicates with the suction chamber, and the other part communicates with the exhaust chamber through the exhaust val...
