Abstract
A resonator for a rotary compressor is provided to prevent generation of impact exciting force and pulsation sound occurred due to pressure pulsation and reduce a noise of a low frequency band generated in the compressor by forming a curved portion at a narrow unit of the resonator which is a pressure pulsation inflow path and controlling the ratio of a diameter to a length of each of the narrow unit and a resonance unit, for thereby smoothing the inflow of the pressure pulsation generated from a pressure chamber. To achieve such a resonator, in a resonator for a rotary compressor, which consists of a narrow unit serving as an inflow path of pressure pulsation which is generated from a compressor and communicating with an exhaust outlet and a resonance unit for reducing a noise by attenuating the pressure pulsation element flowed through the narrow unit, the improved resonator for the rotary compressor according to the present invention includes a curved portion formed at an end portion of the narrow unit. In addition, the ratio of a radius of the curved portion to a diameter of the narrow unit is 2.5˜3.5:1, the ratio of the diameter of the exhaust outlet to the diameter of the resonance unit is 1.2˜1.8:1, the ratio of the diameter to the height of the resonance unit is 1.0˜2.5:1, and the ratio of the length to the diameter of the narrow unit is 1.5˜2.8:1.
