Abstract

958,780. Rotary pumps and motors. R. W. BRUNDAGE. May 19, 1960, No. 6819/64. Divided out of 958,779. Heading F1F. The member 13 which seals the end of chambers 21d rotating about the axis 15 is an interference fit or is welded to the shaft 16 which is axially moveable relative to the housing. As shown the chambers 21d are the working chambers in a gear pump or motor of the type comprising an internally toothed gear meshing with an externally toothed gear. The Specification states that the invention is applicable to vane type or rotating cylinder pumps or motors. A seal 75 has an internal cavity connected via a duct 19 to low pressure and a flange 781 subjected to high pressure maintained in the housing H.
