Internally the compressor has two fundamental groups: the mechanical part (compressor) and the electric part (motor). The motor-compressor assembly is suspended internally by three springs in order to reduce noise caused by its operation.
The compression and suction are made by connecting rod and piston, together with discharge valves and the suction valve.
The eccentric shaft has at its lower end the pumping of oil obtained through the holes in the center of the shaft and the groove in the friction part with the bearing, lubricating all the moving parts and that they suffer friction.
