The invention discloses a rotary compressor and a cylinder thereof. The cylinder of the rotary compressor comprises a cylinder body, wherein a compressing chamber is arranged in the cylinder body; the cylinder body is provided with a suction hole communicated with the compressing chamber, and a sliding blade groove; the suction hole penetrates through the cylinder body in the radial direction of the cylinder body; the suction hole comprises an outer section and an inner section which extend from outside to inside and are communicated with each other; the diameter D of the outer section is greater than the diameter d of the inner section; the axial lines of the outer section and the inner section do not coincide and are parallel; and the distance S between the axial line of the outer section and the axial line of the inner section satisfies 0
Description
technical field [0001] The invention relates to the field of refrigeration, in particular to a rotary compressor and a cylinder thereof. Background technique [0002] The rotary compressor in the related art mainly includes five parts: a compression mechanism, a motor, a rotor, a casing and a pressure accumulator. Among them, the compression mechanism mainly includes a cylinder, and the cylinder is provided with a suction hole and an exhaust hole, and the gaseous refrigerant flows from the suction hole. After entering the cylinder, it is compressed and discharged from the exhaust hole. In the related art, in order to improve the volumetric efficiency of the cylinder compression chamber and reduce the suction resistance loss of the suction hole, the usual method is to reduce the position angle θ of the suction hole and increase the diameter of the suction hole, so as to improve the volumetric efficiency of the rotary compressor. , reducing the suction resistance and power co...
