cylinder continues to extend until the ramp depresses
the activation mechanism on Valve C.
When Valve C is shifted, air is directed to the
Retraction pilot of the four-way directional control
valve. The pilot shifts the valve to direct air to the rod
end of the cylinder. The cylinder begins to retract. The
ramp moves off Valve C, which allows the Retraction
pilot line to vent. The cylinder continues to retract until
the ramp depresses the activation mechanism on Valve B
This allows system air pressure to again activate the
Extension pilot, beginning another sequence. The cylin-
der continues to reciprocate as long as Valve A is held
in the shifted position to keep the system pressurized.
19.6.1 Booster Circuit
A pressure higher than that produced by the system
compressor is sometimes needed for the operation of
a section of a pneumatic circuit. This higher pressure
can be provided by specialized air-to-air or air-to-oil
boosters. Many boosters are basically small-volume,
air-powered reciprocating pumps. They produce inten-
sified pressure for use in a small section of a system.
Figure 19-12 illustrates the circuit and operating
concepts involved in an air-to-air booster. The circuit
shows components in position to begin the process.
When the system is pressurized, air flows through
