Air compression device

摘要

An air compression device is applied in an air compressor, and mainly includes a first rotor, a second rotor, a stop disk, a transmission element and a drive element. When external air enters an air chamber in the air compression device, the air is rotated and compressed by the first rotor and the second rotor, and then is exhausted, the transmission element generates axial displacement vertically according to actual requirements on air admission or exhaust, and drives the drive element and the first rotor to displace, so as to change a capacity of the air chamber, and adjust the air output.

主权项

1. An air compression device, comprising:
a housing, having an air chamber formed therein, wherein the air chamber is in communication with an exhaust channel formed on a surface of the housing; a first rotor and a second rotor, respectively assembled in the air chamber of the housing, wherein the two rotors are relatively rotating to compress the air, and an end of the first rotor is assembled with a rotation shaft casing; a drive element, formed with an engagement portion, wherein the engagement portion is assembled on one end of the second rotor; a transmission element, formed with a first air vent, and assembled on the housing to form an air inlet, wherein the air inlet is in communication with the air chamber, the transmission element is fixed on the rotation shaft casing of the first rotor, and is assembled with the drive element; and when the transmission element displaces axially, the drive element and the first rotor are driven to displace axially, so that the engagement portion acts correspondingly to change a capacity of the air chamber.
