Abstract

96. Obee, W. Jan. 3. Pump relief devices.- Relates to a relief valve applicable for use in connection with feed-pumps for boilers. The passages F and D communicate respectively with the steam boiler and the delivery pipe of the pump, so that, when the pressure in the latter exceeds the pressure due to the steam, the spring G, and the weight of the piston C and the valve B, water passes to the overflow E.
