The throwof eccentrics and crank are each equal to one-half the piston eccentrics are at 90° and 180°, as shown at a. The three pistonvalves are directly connected by rods to thin straps on an angularlymounted cylinder that slides on the shaft by the hand lever for for-ward, stop, or reverse motion. Piston valves are used, taking the steam in the middle and exhaust-ing at the ends. The steam passes from the first valve, through thetriangular space between the cylinders, to the next valve chest. 162. Vertical section through intermediate 163. TYPES OF SLIDEVALVES. Slide valve of theAmes engine. The valve is fin-ished on both sides and rides undera partly balanced pressure plate. STEAM rOWER ArPLTANCES. 8i W^V\V\y^\SSS^ 164. BALANCED PISTON VALVE. The segmental packing,E, is held close to the cylinder wall by the pressure of the steam which enters through holesin the flange, E,shown by the circlesbelow the , live steam connec-tion to receiver oflow-pressure cylin-ders, a supplemen-tary valve operatedby the stem of thepiston valve.
