label: Description
content: The model is a relief panel showing a section through the two steam cylinders of a duplex pump arranged to use steam at boiler pressure in one steam cylinder of small diameter, expand the exhaust steam in a receiver of much larger volume than the small cylinder, and use the steam at low pressure in a second cylinder of larger diameter. This arrangement was devised to permit the use of steam expansively in a duplex pump without the use of two compound cylinders, as was formerly the method.
