The switchover valve applies a partial vacuum to the engine mounts or switches the partial vacuum off. Depending on the application, soft characteristics or hard characteristics are set at the engine mounts.
The partial vacuum is generated by the vacuum pump on the engine. The partial vacuum is fed to the engine mounts through hose lines.
