To open the RAVE valves, the MPEM activates a
solenoid which directs the pressure from air com-
pressor to the valves.
1. Pressure from solenoid
1. Solenoid
2. Pressure from air compressor
3. Pressure to RAVE valves
4. Vent to air intake silencer
5. Check valve
6. Vent from couterbalancing shaft oil cavity
To close the RAVE valves, the MPEM deactivates the
solenoid which blocks the air compressor pressure.
The RAVE valves are opened to the atmosphere.
The vent on couterbalancing shaft oil cavity is nec-
essary to prevent pressure buildup in the cavity by
the air compressor piston movement. The check
valve prevents the eventual possibility of any liquid
that would otherwise flow toward the oil cavity
and be trapped there.
RAVE VALVE OPENED
1. Pressure from air compressor
2. Solenoid activated
3. Pressure to solenoid
4. Pressure to RAVE valves
RAVE VALVE CLOSED
1. Pressure from air compressor
2. Solenoid deactivated
3. Pressure to solenoid
4. Pressure to RAVE valves blocked by the solenoid
5. Vent to air intake silencer
6. Couterbalancing shaft oil cavity vent
7. Check valve
