Abstract
A buffer for storing liquid at a consumer pressure includes a storage volume for holding a liquid and a gas. The storage volume may be separated by a partition element into a liquid compartment for holding the liquid and a gas compartment for holding the gas. A pressurizer is configured for increasing the pressure of gas in the storage volume to an operating pressure when liquid is or has been drained from the storage volume. A ventilator reduces the pressure of gas in the storage volume back to the operating pressure when the storage volume is filled with liquid. A water supply system for an aircraft including the buffer and an aircraft including such a water supply system are disclosed.
Claims11
A buffer for storing liquid at a consumer pressure exceeding an environmental pressure comprising:
- a storage volume for holding the liquid and a gas;
- a pressurizer configured for increasing a pressure of the gas in the storage volume to an operating pressure or maintaining the pressure of the gas in the storage volume at the operating pressure when liquid is or has been drained from the storage volume so that the pressure of liquid in the storage volume is increased to the consumer pressure;
- and
- a ventilator configured for reducing the pressure of the gas in the storage volume back to the operating pressure or maintaining the pressure of the gas in the storage volume at the operating pressure when the storage volume is filled with liquid so that the pressure of the liquid in the storage volume is reduced to the consumer pressure.
