Abstract: A vacuum apparatus for a vacuum compression pack used to store foods is provided. The vacuum apparatus includes a vacuum valve and a piston-type vacuum pump. The vacuum valve is installed in the vacuum compression pack, and the vacuum compression pack is prepared by using a pair of an upper vinyl and a lower vinyl having a sheet structure. Three edges of the vacuum compression pack are thermally compressed to seal the vacuum compression pack, and one edge of the vacuum compression pack is equipped with a zipper to seal the vacuum compression pack. The piston-type vacuum pump is installed in the vacuum compression pack such that the vacuum valve is buried in the vacuum pump.
