摘要：
A swash plate type compressor having pistons, each defining on opposite sides compression chambers 38 and 39. The cross sectional area of the operating chamber 39 located adjacent the driving source is larger than the cross sectional area of the operating chamber 38 located away from the driving source in such a manner that the axial force F0 generated in a rotating shaft 5 due to the difference between the pressure at the swash plate chamber and the atmospheric pressure is substantially canceled by the axial forces F1 and F2 generated in the rotating shaft due to the refrigerant pressure acting on the piston 8 in the operating chambers 38 and 39.
