Abstract

691,503. Rotary pumps. EDNELL, F. G. June 28, 1951, No. 15407/51. Class 110(ii) A pump comprises a rotatable screw 11 eccentrically located in a cylindrical chamber within a housing 3 and having a groove of triangular crosssection receiving a corresponding screw-like body 5 which rotates with the screw. The chamber may have a liner 4. One side of the triangular crosssection extends at right angles to the axis of rotation.
