MULTISTAGE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide a multistage compressor which prevents leakage of fluid under an increasing state of compression ratio, and eliminates malfunction of a link mechanism such as vibration. SOLUTION: A suction chamber 15, an intermediate chamber 14 and a discharge member 13 are formed on a housing. A first bore 7 with a large inner diameter is communicated with the suction chamber 15 and the intermediate chamber 14 through an intake valve and a discharge valve. A bore 8 with a small inner diameter is communicated with the intermediate chamber 14 and the discharge chamber 13 through the intake valve and discharge valve. The first bore 7 with large inner diameter and the bore 8 with small inner diameter are plurally formed respectively. They are arranged around a driving shaft 24 in each kind parallely to each other and alternatively.
