Title:
LOCKABLE COMPRESSIBLE FLUID ACTUATOR
Document Type and Number:
WIPO Patent Application WO2007059126
Kind Code:
A9
Abstract:
The load handling system of the preferred embodiment includes a lockable strut, a hydraulic cavity, a reservoir, and a volume modulator. The lockable strut includes a compressible fluid, a hydraulic tube that defines an inner cavity and contains a portion of the compressible fluid, a displacement rod to move into and out of the inner cavity, a cavity piston connected to the displacement rod and extending to the hydraulic tube, thereby separating the inner cavity into a first section and a second section, a passage to allow flow of the compressible fluid between the first section and the second section of the inner cavity, a controllable valve to selectively restrict the flow of the compressible fluid between the first section and the second section of the inner cavity through the passage, an electric control unit to selectively activate the controllable valve, thereby actively substantially locking or unlocking the lockable strut.
