Abstract

795,204. Rotary pumps. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 19, 1956 [July 20, 1955], No. 20941/55. Drawings to Specification. Class 110 (2). In a rotary oil vacuum pump of the outwardly-sliding radial vane type the contacting surfaces of the pump such as the vanes and the abutment are made of anti-friction material such as copper impregnated with polytetrafluorethylene or molybdenum having a molybdenum sulphide bearing surface.
