Abstract
A chamber valve () for use in processes requiring vacuum pressures has a compact design which minimizes the space needed for the valve in the travel direction. The chamber valve gate () is moveable between a first position in which the gate is offset from the portal (), and a second position in which the gate is aligned with the portal. The gate will move into alignment with the portal while remaining within a plane parallel or nearly parallel to the portal.
