And compressor bypass mechanism

The utility model discloses a bypass mechanism and a compressor. The bypass mechanism comprises a valve seat, a sealing film, a magnet and a bracket, wherein a main body of the bracket is of a cylindrical ring structure, a supporting table used for holding the sealing film is arranged at the inner side of the main body, and the table-board of the supporting table is higher than the main body of the bracket; the magnet is fixedly arranged below the supporting table; the valve seat is arranged above the supporting table; the sealing film is attracted on the supporting table by virtue of the magnet and can move to a gas opening of the valve seat so as to close the gas opening; and when the sealing film is arranged on the supporting table, gas can pass through the bypass mechanism. The bypass mechanism is simple in overall structure and can be mounted and used in a single-cylinder or multi-cylinder compressor, and the varying capacity of the compressor is realized, so that the requirement for input of lower cooling capacity to the compressor is met. Moreover, the magnet is arranged inside the bracket, so that the sealing film can be effectively prevented from moving up and down, and possibly caused noise of the compressor body is reduced.
