BA9 Booster-Accumulator

The Miller BA9 supplies much larger volumes of high pressure oil for operating hydraulic cylinders in single acting closed booster circuits and can also be used in double-acting circuits. 

Used as an accumulator, it serves as an auxiliary, large capacity source of high pressure hydraulic power derived from low pressure input. 

The unit consists of an air or hydraulic piston driving a smaller diameter hydraulic piston, resulting in  a pressure intensification according to the ratio of the piston areas. 

The larger the ratio, the greater the pressure intensification.

 

The BA9 is lower in first cost than the B4 Booster but is not self-bleeding nor self-filling. 

Therefore, its use is recommended only where complete manual bleeding and filling can be easily accomplished. 

The fluid driving media may be air or low pressure hydraulic.
