Fig. 2 An air cylinder was used to

open and close the original mechanical

valve as shown. This air cylinder was

controlled by a manually operated 2-

way air valve. The air cylinder moves

the mechanical valve from its closed to

open position. The amount of opening

was pre-set by the operator by adjust-

ing a nut on the linkage of the air cylin-

der to limit the stroke.

Fig. 3 This figure shows an ammeter

reading of approximately 8 amps, the

no-load or no shot flow condition. A

conventional panel ammeter (0-30

Amps) was used to indicate motor

amps and relative shot flow rate. It is

not uncommon for these meters to be

inaccurate because metallic dust col-

lects inside the meter movement

mechanism. This prevents the meter

from displaying the proper amperage.
