PURPOSE:To make it possible to arbitrarily control a volume to be compressed by providing a hole penetrating a blade at a proper position thereof in its thickness direction in a rolling piston type compressor. CONSTITUTION:An eccentric rotor 2 is made rotatable within the cylinder chamber 1a of a cylinder 1 while slidably making contact with the cylinder, and the inside of the cylinder chamber 1 is compartmented into high and low pressure sides by a blade 5. Further, a discharge port 3 and an intake port 4 are provided on the both sides between which the blade 5 is positioned, and a hole 6 is provided at a proper position apart from the tip part of the blade 5 resiliently making contact with the rotor 2 and projecting inside the cylinder chamber 1a. And, a volume to be compressed can be controlled by permitting both low and high pressure sides to communicate with each other when said hole 6 reaches the inside of the cylinder 1a. |
