their stroke.
d. Electro/Hydraulic Mini-Valve Assemblies -These
direct the fluid to the appropriate hydraulic cylin-
ders.

provide a path for the hydraulic oil.
f. Hydraulic Cylinders - They convert the hydraulic
fluid pressure and volume into mechanical motion.

1-1. General
Electro-Hydraulic System
The hydraulic system (with the exception of the
hydraulic cylinders and hoses) is contained within
the base of the table. The hydraulic valves and
pump are electrically controlled by the use of a
hand-held push button pendant control. The power
requirements for the table are 120 VAC, 5 amp, 60
Hz.
The table contains the following components. Re-
fer to the block diagram (figure 1-1) for relationship.
a. Oil Reservoir - Main oil supply. Approximately
two quarts.
b. Motor/Pump Assembly - A positive displace-
ment gear type pump provides the necessary oil
pressure and volume.
