Suction throttle valve

The suction throttle valve is attached to the tandem pump.

When the vehicle is being driven straight ahead, the volumetric flow of the tandem pump is throttled on the intake side by the application of current. This lowers the pressure of the circulating flow. The tandem pump consumes less power. This lowers CO2 emissions.
