Substances e.g. anti-freezing agent and splash water, mixing and conveying device for motor vehicle, has passage cross sections changed by relative-adjustable movement, such that one cross section is reduced when other section is increased

摘要

The device has reservoirs storing substances such as anti-freezing agent and splash water, and a conveying pump conveying the substances along conveying paths from the reservoirs to a load device. A reservoir-conveying line (28) stays in conveying connection with one reservoir. Passage cross sections (66, 68) are changed along sections of preset relative adjustable regions by relative-adjustable movement between dosing-inlet openings (62, 64) and reservoir-outlet openings (51, 52), such that the cross section is reduced when the other cross section is increased by the movement.
