Thermal Vacuum Valve: Description and Operation
Temperature Control Valve
Fig. 26 - EGR Control Temperature Control Valve
The plenum mounted temperature control valve is utilized on the ported vacuum control system. The valve reduces the recycle rate at low ambient
temperature for improved driveability. The unit contains a temperature sensitive bimetal disc which senses plenum air temperature. The snap
action of the disc unplugs a calibrated orifice to provide the bleed air. Calibration is protected by an air filter unit.
