Abstract

301,610. Jacobsen, O. A. E. Oct. 26, 1927. Single-acting suction-valveless piston pumps; valves, arrangement of.-A pump comprises two coaxial plungers B, C of equal diameters controlling respectively the inlet and delivery ports H, J. The plunger B is returned on the suction stroke by a spring G, and the plunger C is returned to close the port J by a spring F.
