Abstract
The present invention relates to a vacuum pump using a profile. The vacuum pump according to the present invention comprises: a hollow profile having a longitudinal mounting hole and a vacuum chamber formed adjacent to each other; an ejector pump arranged inside the mounting hole in the longitudinal direction; and end caps provided in both openings of the profile, respectively, so as to have a through-hole formed therein so as to correspond to the inflow opening or the discharge opening. Particularly, the first cap near the inflow opening is designed to have a passage through which the vacuum chamber and the mounting hole communicate with each other. The vacuum pump structure according to the present invention is considered to be a vacuum pump structure using at least a so-called “profile” best designed to make fabrication of the vacuum pump convenient and to improve vacuum characteristics.
