Abstract
The invention provides an eccentric rotor air compressor which comprises a rotor, a shell, a bolt piece device, an air inlet and an air outlet. A shell cavity capable of compressing air is formed between the rotor and the shell. The rotor is eccentrically arranged in the shell cavity. A shutoff valve is arranged among one side of the rotor and two points on one side of the shell cavity. The air inlet and the air outlet are formed in the two sides of the shutoff valve respectively. End sealing pressing sheets are arranged at the two ends of the shell cavity. The sealing strength of each end sealing pressing sheet is automatically adjusted through an inflation air bag communicated with an air tank. The rotor is provided with rotor grooves. Bolt pieces move in a reciprocating manner in the rotor grooves. Bolt piece end sealing devices abut against the inner wall of the shell cavity and the sealing angles can be automatically adjusted. When the air compressor works, power is input through a rotor shaft, the rotor drives the bolt pieces to rotate, compressed air in the shell cavity is exhausted through the air outlet, meanwhile fresh air is sucked in through the air inlet, the double effects of air inflow and compressed air exhausting can be achieved at the same time through the same rotation action, and the compressed air can be continuously obtained through circulating reciprocating motion.
