_The Worthington Pressure Pump._ This pump, presented in Fig. 446,
is specially designed for use in connection with hydraulic lifts
and cranes, cotton presses, testing machines, hydraulic riveting
and punching machines and hydraulic presses of all kinds. Also, for
oil-pipe lines, mining purposes and services requiring the delivery of
liquids under heavy pressures.
There are four, single-acting, outside-packed plungers, which work
through the ends of the water cylinders, the latter having central
partitions. The arrangement of compound steam cylinders shown in
Fig. 445, or a triple expansion arrangement, can be applied to these
pumps where a saving of fuel is desired. The water valves are easily
accessible and are contained in small independent chambers, capable of
resisting very heavy pressure.
