Abstract: PURPOSE: A vacuum pump is provided to improve use convenience by reducing a failure rate and to be replaced depending on a surrounding situation. CONSTITUTION: A vacuum pump(100) comprises a housing(110), a supporter(120), injection valves(130), and exhaust pipes(140). The housing has an empty space. A suction port(112) is formed in the bottom of the housing. The supporter is coupled to the top of the housing and is composed of an upper plate(121), a body(124), and an air injection tube(125). The injection valve is installed in a mounting hole of the air injection tube. The exhaust pipes reduce the speed of air exhausted from the injection valve.
