Anti Sink

What is a Anti Sink?

When an Anti Sink system is fitted (SC/ MAC) it keeps the car from lowering when not in use. The system does not interfere with the normal functioning of the vehicle. The Anti valve is the only place where leaks can occur this reduces the risk elsewhere in the system.

There is an Anti Sink valve fitted for each axle, between the height corrector and the suspension struts (or the hydraulic control block on Hydractive systems). The valves operate on the pressure differences in the system, without any electrical control. When there is significant pressure in the control circuit, they keep the work circuit constantly open, similar to a simple electrical relay.

Under normal circumstances, the high pressure pump supplies the regulator and the main accumulator with fluid. The output from these two feeds the whole system, going through the security valve which maintains pressure to the brake circuit. If there is enough pressure in the system, the security valve feeds the rest of the suspension via the Anti Sink valves and the height correctors.

When the car runs, the valves are constantly open, connecting the height correctors to the rest of the suspension and brake subsystems — everything functions in exactly the same way as a standard car that is not fitted with Anti Sink. Even when the engine is turned off, the valves remain open as long as the feed from the accumulator remains at a higher pressure than that of the suspension.
