A rolling piston type rotary compressor includes a cylindrical cylinder having a motor and a compression unit driven by the motor disposed inside of an enclosed container. A roller is externally fitted to the crank of a drive shaft coupled to the motor for moving along the inner side of the cylinder. Plural blades move in and out of the cylinder so that the leading end may slide on the outer circumference of the roller. This partitions the compression chamber formed by the inner side of the cylinder and the outer circumference of the roller nearly at same intervals. A suction port and a discharge port are disposed in each divided compression chamber, in which a common muffler chamber is disposed between the suction port of each compression chamber and the compressor external suction piping system. Each suction passage from each suction port to the muffler chamber is nearly at a same length. Equal pressure pulsation occurs in each suction passage, the suction efficiency of each compression chamber is equal, the compression torque fluctuation during one revolution of the drive shaft is dispersed, and hence the efficiency of the motor is enhanced and the vibration of the compressor piping system is reduced.
