Abstract
692,823. Rotary pumps or motors. COMMERCIAL SHEARING & STAMPING CO. Jan. 18, 1951 [Jan. 18, 1950], No. 1391/51. Class 110(ii) An end plate 14, for a pump or motor having one or more impellers 11, 12, shown as gears, is provided on one face with channels 29 to 33 containing rubber-like packing means, such as neoprene, 34 to 38. Fig. 1 shows a pump with gear journals 22, 23 extending axially with needle bearings 21, the ends of which extend into annular cavities within end plates 13, 14. Lands 43 to 48 are provided between relieved sections of the plates to allow for thermal expansion without buckling being sliding fits in the casing. The lands also secure alignment of the plates and impellers, dowels not being used between the plates and the casing parts. Ports 15a, 15b are provided for admission and discharge of fluid. Grooves 28, in the front of each plate at the waist portion, carry fluid compressed between meshing impeller teeth back to the outlet side of the pump. The end plates are preferably of bronze, the casing member 15 of iron, and the impellers of steel.
