Abstract

141,826. Allen, G. W. Jan. 29, 1919. Double-acting bucket pumps; concussion-preventing; valves, arrangement of; valves, facilitating removal of.-A double-acting pump comprises a casing 1 provided with two suction passages 4 closed by valves 3, and a piston provided at each end with a delivery valve 8, the valves being so arranged that at the end of the stroke the clearance is a minimum. One or both valves may have projections &c. 10, 11, so that when the piston is pushed hard over at the end of the stroke, the valves are slightly opened to enable the pump to be emptied. A drain-cock is provided at the bottom of the casing. The valves 3 are carried by detachable plates 2. The projections &c. on the valves may be in the form of buffers or spring plungers which minimize concussion.
