Abstract

Valve arrangement for guiding a liquid against a gas pressure gradient. The valve arrangement includes first, second and third pressure areas connected in series. An intake opens into the first pressure area. An outlet opens into the third pressure area. Flow check valves selectively open or close passage openings between the first and second pressure areas and between the second and third pressure areas. Whereby the flow check valves, free from outside influences, are opened when in a resting position and are automatically held in a closed position by gas counterpressure. Whereby the first and third pressure areas are respectively connected to the second pressure area via a ventilation line. Whereby a ventilation valve coupled to at least one of the ventilation lines, the ventilation valve selectively opening or closing the at least one of the ventilation lines. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
