<p>PURPOSE: To provide a compact compressor with low vibration and high efficiency by forming the first working chamber on one end face of a rotary piston and forming the second working chamber in the perpendicular direction while bringing it into contact with the outer circumference in the rotary piston when the revolving rotary piston is reciprocated in the longitudinal direction and in the direction perpendicular to the longitudinal direction. CONSTITUTION: When a crankshaft 2 is rotated, a rotary piston is revolved so as to be reciprocated in the inside of a rotary piston bore part 4a. On the other hand, a fixed piston 5 is reciprocated in the inside of a fixed piston bore part, 4c. In this way, increase and decrease of displacement are repeated in four chambers including two working chambers 12 provided with comparatively large displacement on the first level and two working chambers 13 provided with comparatively small displacement on the second level. A working medium compressed in the working chambers 12 is passed through a discharge port 6c to be discharged to a space 19 in a container and sucked into the working chambers 13 so as to be compressed, and then, passed through a discharge port 5c and passed through the inside of the fixed piston 5 so as to be discharged from a discharge port 24.</p> |
