Abstract

An improved liquid ring machine having a housing that has a circular inside contour and side shields arranged at its faces, at least one of which is provided with a control disk. The rotor of the machine is eccentrically mounted in the side shields to rotate relative to the machine housing. The rotor comprises a hub, blades, and a center wall that extends radially over the entire circumference of the rotor from the rotor hub to the free end of the blades. A partition wall is attached to the machine housing, lies in the same plane as the center wall and surrounds the center wall such that a gap exists between the center wall and the partition wall. The gap may be easily adjusted by pivoting the machine housing relative to the side shields, i.e., the control disks, and the rotor, around a pivot point that lies outside of the center axis. The machine housing may be secured in place in its pivoted position in each instance. Use of this pivot point provides a more uniform change in gap between the center wall and partition wall, and adjustments to the partition wall are not necessary, thus permitting the machine housing and partition wall to be provided as a unitary element.
