ABSTRACT:
A hydraulic booster unit and system for use in operating hydraulic units, such as work holding hydraulic cylinders, from a compressed air power source is disclosed. The booster includes a unique refill unit that automatically feeds hydraulic fluid from a reservoir to the booster to replace lost fluid during use, and also includes an alerter for giving warning on the onset of a low fluid condition (such as may occur from an exhausted reservoir or excessive leak), and thus protects against excessive leakage as well as the dangers to the work piece and worker inerent in a low fluid condition. The alerter may be a visual unit or a compressed air-operated audible alarm or both.
