4.2 - FAN SERVO AMPLIFIER
Servo amplifier
A free-wheeling gear is included between the
Power Take-off of the servo amplifier and the fan
control pulley (refer to the Picture).
In case of sudden decelerations or unexpected
engine Stoppages, this allows the fan to continue
its free rotation, thus avoiding extreme mechan-
ical stresses to be transmitted to the drive mem-
bers..
Centrifugal fan
The front-engaging clutch assembled on the fans shaft allows the operating of the centrifugal pump
by excluding that of the fan.
The fan housing can rotate by 360 degrees. This permits the positioning of the outlet spout at the point
necessary for the assembling of the different distribution devices.
An air intake, pre-set on the outer edge of the housing, is connected to the plunger tap placed above
the tank. Through this tap it is possible to carry out or exclude the pneumatic shaking of the mixture.
The centrifugal close-propellers fan is built out of steel plate; the air intake on the housing is protected
by an apposite grill.
