Patent ID: 8801402

Claim:
An air compression device, comprising: a main seat body, having an air inlet, wherein an air chamber is formed in the main seat body, the air inlet is in communication with the air chamber, a first rotor and a second rotor are assembled in the air chamber, and the two rotors rotate relatively to compress air entering the air chamber; a first cover body, assembled on one side of the main seat body, wherein after the assembly, one end of the first rotor and one end of the second rotor are respectively pivoted in corresponding shaft holes formed in the first cover body, an accommodation slot is formed on a plane of the first cover body, an exhaust passage is formed by inner edges of the accommodation slot, and an exhaust hole is formed at one end of the exhaust passage; a pressure regulating disk, pivoted in the accommodation slot of the first cover body, and capable of deflecting in the accommodation slot, wherein a valve is formed on a surface of the pressure regulating disk, and after the pressure regulating disk is pivoted at the first cover body, the valve is in communication with the exhaust passage of the first cover body; an actuating portion, assembled in linkage with the pressure regulating disk, wherein when the actuating portion acts, the pressure regulating disk is made to deflect through linkage; and a second cover body, assembled on another side of the main seat body, so that the other end of the first rotor and the other end of the second rotor are respectively pivoted in corresponding shaft holes formed in the second cover body, wherein a gear disk is formed on a side plane of the pressure regulating disk, so that one end of the actuating portion is engaged with the gear disk to achieve linkage.
