Abstract

150,706. Friedmann, A. [Firm of]. Dec. 2,1918, [Convention date]. Lever-actuated pumps; stroke, varying; singleacting multiple delivery pumps; valve-gear. - A single-acting multiple delivery pump comprises a plunger 1 actuated by a double cam 7 through a lever 8 and adapted to deliver alternately through the pipes 3, 4. The valve 2 controlling the inlet 5 and the pipes 3, 4 is actuated by an eccentric or cam 10 and lever 11, and makes one reciprocation, while the plunger 1 makes two. The stroke of the plunger 1 may be varied by means of a screwed rod 9 engaging the lever 8.
