To quickly assess the difficulty of the text, read a short excerpt:
As will be seen, the ram has two diameters, so that on its up stroke, or its movement in the direction indicated by the arrow, a vacuous spsice is formed in the cylinder, and the water thus enters through the suction connection a ; whilst on the down stroke there is a corresponding displacement, whereby water is forced out from the cylinder through the delivery connection h. Both the suction and delivery connections are, of course, provided with suitable valves. With onlv a small difference in ...the V//////////////////A ^ Of Fig. 49. a,reas of the respective ends of the ram, there will be but a small discharge on each pump stroke, and thus we can provide ample cross-sectional area throughout the ram to resist any desired intensity of pressure, without affecting the quantity of water delivered. Fig 49 is a sketch diagram of the ram and piston type of water end frequently employed in rotative hydraulic pumping engines, for the purpose of obtaining the advantages of the equalisation of the work, and a steady flow resulting from a double action on the delivery side, with the simplicity of a single action on the suction side.
