Abstract

938,559. Rotary exhausters. H. BURGER. Dec. 1, 1961 [Dec. 8, 1960], No. 43001/61. Class 110 (2). A rotary compressor or vacuum pump comprises a rotor 5 mounted eccentrically within a cylindrical casing 4 on a vertical shaft 23 and having a diametral sliding vane 6, circular cover plates 1 and 7, the upper of which consists of a flat plate 1 provided with inlet and outlet openings 2 and 3. Two further casings 10, 11, of similar dimensions are bonded to flanges 12, 13, and form respectively inlet and exhaust compartments 17, 16, and an oil tank in which the rotor casing 4 is submerged for sealing purposes. Oil also partly fills the exhaust compartment 16, submerging the exhaust valve 21. The cylindrical surfaces 26 of the casings 10 and 11 (Fig. 3) may be of glass or transparent synthetic plastic, bonded to the covers 27 by synthetic adhesive. Adhesive bonding is also used to mount the stuffing box 24 and to fix the oil tank 11 into a recess in a bedplate (Fig. 4, not shown). Since castings are not used for the major components, corrosionresistant steels may be used without undue expense.
