The invention provides an air cylinder base assembly, a pump body assembly and a refrigerator. The air cylinder base assembly comprises a cavity and separation parts. The separation parts are arrangedin the cavity and divide the cavity into noise reduction chambers with the different volumes. Through holes which enable the adjacent noise reduction chambers to communicate are formed in the separation parts. The separation parts are arranged in the cavity, the cavity is divided into the multiple adjacent noise reduction chambers which communicate with each other, multiple kinds of noise with different noise frequencies can be eliminated, and the exhaust noise is lowered. 本发明提供一种气缸座组件、泵体组件和冰箱。该气缸座组件包括腔室和分隔件，所述分隔件设在所述腔室内，将所述腔室分隔为容积不同的消音室；所述分隔件上设有导通相邻所述消音室的通孔。通过在腔室内设置分隔件，腔室被分隔为多个相邻导通的消音室，能消除多个不同音频的噪音，从而降低排气噪音。
