An apparatus for extracting water from atmospheric air by means of a flowable sorbent for the sorption of the water, wherein the sorption by way of the flowable sorbent (3) is provided at least along a sorption path (2) of the sorbent (3), wherein a sorbent (4) diluted with sorbed water (17) is provided at the end of the sorption path (2), wherein a separation unit (12) for at least partially separating the sorbed water (17) from the flowable sorbent (3, 4) is provided, wherein the separation unit (12) has at least one evaporator (12) for the evaporation of the sorbed water (17), is proposed, which apparatus can be operated in an energy-efficient manner and is not imperatively reliant on the presence of solar energy. This is achieved according to the invention in that the separation unit (12) has at least one negative-pressure compressor (16) for subjecting the diluted sorbent (4) to negative pressure.

The apparatus as claimed in one of the preceding claims, characterized in that a drive apparatus of the piston (21) has at least two diverting elements (29), which are spaced apart from one another and which are rotatable about in each case one drive spindle, and at least one endless circulating drive element (27) which connects the two diverting elements (29).
The apparatus as claimed in one of the preceding claims, characterized in that at least two drive apparatuses are provided so as to be arranged to both sides of the piston (21), wherein a connecting element (26, 28) to the piston (21) is provided between the two endless circulating drive elements (27) of the two drive apparatuses.
The apparatus as claimed in one of the preceding claims, characterized in that the cylinder (22) is pivotable about a pivot axis (31) which is arranged perpendicular to the cylinder longitudinal axis.
The apparatus as claimed in one of the preceding claims, characterized in that the piston (21) is arranged between two pressure chambers (23, 24) of the cylinder (22).
The apparatus as claimed in one of the preceding claims, characterized in that the separation unit (12) has at least one condensation apparatus (13) for condensing the separated-off water (14).
The apparatus as claimed in one of the preceding claims, characterized in that at least one heat exchanger wall is arranged between the evaporator (12) and the condensation apparatus (13).
The apparatus as claimed in one of the preceding claims, characterized in that, between the sorption path (2) and the separation unit (12), there is arranged at least one preheating unit (9, 10, 11) for the preheating of the diluted sorbent (4).
The apparatus as claimed in one of the preceding claims, characterized in that the preheating unit (9, 10, 11) has at least one heat exchanger (9, 10) for the exchange of heat between the diluted sorbent (4) and the separated-off water (14, 17) and/or the flowable sorbent (3).
