  "abstract": "The present invention relates to a valve module for a vacuum pump, and the valve module includes a through-body mounted on a communication-hole of the vacuum pump, and a valve disposed in the body to open and close a central 5 passage while moving upward/downward. In the present invention, particularly, an exhaust path of the pad includes one or more longitudinal air guide-grooves, which are defined in an inner wall or an outer wall and are disposed between the inner wall of the space part and the outer wall of the 10 valve to serve as an air passage connected to the passage, and a gap or micro-hole defined between the valve and the body to communicate with the guide-groove and the central passage. Therefore, there is no concern that the passage is blocked or deformed even though the body is made of an 15 elastically deformable material.",
