Basic Bootstrap Reservoirs provide a storage container for changes in aircraft hydraulic system volume due to extremes in fluid temperature.  They also generate aircraft return pressure, which prevents hydraulic pump cavitation and provides additional system pressure volume when unequal area actuators extend, improving performance.  Please see the data sheets in our Product Resources section below for more information.
