1. A system for providing a pressurized liquid, having:
a reservoir for accommodating the liquid, which has a discharge and a feed;
a pressure-increasing device;
a first valve;
a separate filter chamber, which has an inlet and at least one outlet; and
a compressible, closed buffer body,
wherein the pressure-increasing device is coupled to the filter chamber and is configured to increase a pressure of the liquid within the filter chamber,
wherein the first valve is between the feed of the reservoir and the filter chamber and is configured to open in a direction of the reservoir upon attainment or exceedance of a minimum pressure of the liquid in the filter chamber, and
wherein the buffer body is in the filter chamber such that the buffer body can be surrounded by liquid.
