GF09.20-P-6001AMG Component Description For The Variable Intake Manifold Switchover Valve







The switchover valve is mounted at the front of variable intake manifold.

Task
The switchover valve applies vacuum to variable intake manifold vacuum unit to intake manifold switchover (long intake routes) or ventilates it again (short intake routes).

Design
The switchover valve is an electromagnetic switchover valve which is cast in a plastic housing. The coil resistance about 30 ohms at 20 °C.







The switchover valve is actuated by the ME-SFI control unit (N3/10) from the ground side via its own output stage. The voltage supply takes place from "circuit 87 M2e".

In an activate condition a valve plate is pulled by solenoids and a rubber seal closes the connection (3). The connection between the connection (2) and connection (1) is released in this way and the vacuum from the vacuum reservoir is built up to the vacuum unit.

In the deenergized state the link again exists between connection 2 and 3 through which Connection 1 is supplied with air again.
