OPENTECHNICAL PUBLICATION OT-2026-000002686 Valve module for vacuum pump Published: 2026-09-15T19:14:40.201049Z Permanent URL: https://opentechnical.org/p/OT-2026-000002686 Categories: Industrial Motion & Power Transmission > Fluid Power ------------------------------------------------------------------------ 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 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 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 elastically deformable material. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002686 Published 2026-09-15T19:14:40.201049Z https://opentechnical.org/p/OT-2026-000002686
