Abstract
In one aspect of the present invention, a system for performing work has a hydraulic circuit adapted to store energy within a hose. The hose has an elastic inner layer pre-tensioned by a radial tensioning component disposed within the hose and at least one reinforcing layer of elastic thread disposed around and compressing the inner layer. A hydraulic fluid is in the circuit and in communication with the hose, the radial tensioning component and with a hydraulic actuator for doing the work. The circuit has a mechanism for pressurizing the hydraulic circuit in order to perform the work.
