. Appleton's dictionary of machines, mechanics, engine-work, and engineering. sides of the cylinder are two pipes A B and C D; where A B descends into the well, andC D conveys the water to the reservoir.

Suppose the cylinder and pipes filled with water, then in an upward strokeof the piston, the valves a and e are opened, and c and b are closed; the water is forced by the pistonthrough the valve e and then up the vertical pipe C D; at the same time the water, by the atmosphericpressure, rises up the pipe A, and opening the valve a follows the piston in its ascent: on the contrary,when the piston descends, the valves a and e are closed, and c and b are opened; the water is thenforced through the valve c, up the vertical pipe C D, and the water from the well enters the cylinderthrough the valve b, and follows the piston in its descent; and so on to any number of strokes.
