what is the energy storage device of the hydraulic system

LECTURE 28 to 29 ACCUMULATORS FREQUENTLY ASKED …

1. Define an accumulator and explain its function. A hydraulic accumulator is a device that stores the potential energy of an incompressible fluid held under pressure by an external source against some dynamic force. This dynamic force can come from different sources. The stored potential energy in the accumulator is a quick secondary source of ...
