PURPOSE:To simplify the mechanism, reduce the leakage of compression and permit to drive the compressor with a small driving power by converting the rotary motion of a driving shaft into the oscillating motion of a piston and compressing the suction gas alternately. CONSTITUTION:When the driving shaft 8 is rotated and an oscillating cam 7 is oscillated, one of operating chambers is expanded and the operating chamber becomes vacuum, therefore, the gas is sucked into the operating chamber through a suction port 12 under opening a reed valve. When the driving shaft 8 is rotated further from a position, whereat the volume of one of the operating chambers become the maximum confining volume, into clockwise direction, the volume of one of the operating chamber is compressed and the compressed gas opens the reed valve and is discharged out of a delivery port 14. At this time, the operation chamber at the other side is expanded in the volume thereof and sucks the gas. Thus, the oscillating piston 7 is oscillated by the rotation of the driving shaft 8 and the suction and delivery motions may be effected sequentially and alternately. |
