Abstract

676,160. Gear pumps. PERRY, A. E. May 25, 1950, No. 13203/50. Addition to 676.013. Class 110(ii) A pump J, of the internally-meshing gear type, is provided with a piston valve O in its delivery pipe which opens the pump to delivery at a predetermined pressure. At a greater pressure byepass means open: these comprise ports S in the valve wall which line up with byepass ports T leading back to the pump inlet. The valve spring R is adjustable. An oil seal F, G, as described in the parent Specification, is surrounded by a filter. Another filter surrounds the pump.
