The valve U is operated by a camon the shaft S, to cut off for , B, is a riding valve in contact with theelliptic cylinder, which has a packing slide,S, P, concentric with the axis and followingthe wall of the shell as a packing. Steam follows at half or less part of arevolution and then expands to the exhaustport, C. no STEAM POWER APPLIANCES. 264. STEAM RAM for elevating water. Erwin type. PenberthyInjector Co. Water is elevated by the alternate action of steam andatmospheric pressure. The steam having first driventhe water from the ram is instantaneously condensedand a vacuum is formed. A volume of water is thendriven into the ram by atmospheric pressure. The ram is placed beneath the surface of thewater in the well or other source of supply and,before starting, water flows into it by gravity. Whensteam is turned on it passes through the steam pipeA, nipple C, conical screen D, the main steam port E,and radial steam ports F into the cylind
