ABSTRACT

The present invention relates to a valve module for a vacuum pump, and the
valve module includes a through-body (11) mounted on a communication-hole
(113) of the vacuum pump, and a valve (13) disposed in the body (11) to open
and close a central passage (12) while moving upward/downward. In the present
invention, particularly, an exhaust path (17) of a pad (120) includes one or
more longitudinal air guide-grooves (18), which are defined in an inner wall
(15a) or an outer wall (13a) and are disposed between the inner wall (15a) of
a space part (15) and the outer wall (13a) of the valve (13) to serve as an
air passage connected to the passage (12), and a gap or micro-hole (20)
defined between the valve (13) and the body (11) to communicate with the
guide-groove and the central passage (12). Therefore, there is no concern that
the passage is blocked or deformed even though the body (11) is made of an
elastically deformable material.
