Abstract: A vacuum assist pump system includes a vacuum assist pump for assisting to a brake system by vacuum, wherein it includes a suction compensation pump connected with the vacuum assist pump. Advantageously, a vacuum compensation reservoir is arranged between the vacuum assist pump and the suction compensation pump. The vacuum compensation reservoir comprises a vacuity sensor for its internal vacuity and two interfaces. One of the two interfaces communicates to the suction compensation pump, the other communicates to the vacuum assist pump.

Abstract: The present invention relates to an electronic control fuel saving clutch device for a vehicle, comprising: an electronic control clutch (7), a brake switch (8), an accelerator sensor (9) and an electromagnetic fuel line throttle valve (G) for opening and closing the accelerated fuel supply; the electronic control clutch and the electromagnetic fuel line throttle valve are controlled by the brake switch and signals emitted by the accelerator sensor, wherein when the brake switch is switched on, the electronic clutch is engaged, and the electromagnetic fuel line throttle valve is closed, and the engine is supplied only with the idle fuel supply; when the brake switch is switched off, if the accelerator sensor detects that the accelerator pedal (P) goes forward or keeps in a certain forward position, the electronic control clutch is engaged and the electromagnetic fuel line throttle valve is open, then the accelerating fuel supply is switched on, and the engine is supplied with the accelerating fuel supply; if
