FUEL ACTUATOR

The 175 SERIES electric actuator is designed io mount directly on a Bosch "P" size fuel injection pump,
with a right hand rack, in place of the mechanical governor. When the 175 actuator is installed on the fuel
pump, an optimum performance, long life fuel control system results. An external fuel shut off lever is
provided to manually override the actuator's control. Also provided is an adjustable internal maximum fuel
limit.
The 175 Series Electric Actuator can control fuel pumps of up to 8 cylinders. The actuator was designed
with two isolated chambers. The upper chamber is wet with oil and contains the connection to the Fuel
rack and art optional manual shut off mechanism. The sealed lower chamber contains electromagnetic
components.
This design eliminates the possibility of magnetic particles or other oil contaminants interfering with the
operation of the electric actuator. Unreliable devices such as bellows and sliding seals are not used so
that no maintenance is required. The designed life of the actuator is typically longer than. that of the
engine
