Abstract
A hydraulic demonstration apparatus is disclosed having a hydraulic system including a reservoir, an inlet line and an outlet line. A valve at the inlet line is included for introducing air so as to create aeration in the hydraulic system. A restricting valve is provided at the inlet line for creating cavitation in the hydraulic system. A hydraulic pump is provided having a clear cover for observing the effects of aeration and cavitation inside the pump. A flow meter having a clear housing is provided for observing the air in the system and the reduction of pump efficiency caused by aeration. The demonstration apparatus can be mounted on a movable cart.
