PRESSURE RELIEF APPARATUS FOR HYDROPNEUMATIC VESSEL

摘要

A hydropneumatic system is disclosed comprising a fluid vessel comprising an incompressible fluid portion and a compressible fluid portion to contain a compressible fluid at a first pressure, the compressible fluid portion being in pressure communication with the incompressible fluid portion and separated from the incompressible fluid portion by a flexible barrier. Such embodiments further comprise an incompressible fluid source to supply an incompressible fluid at a second pressure to the incompressible fluid portion, the first pressure being in substantial equilibrium with the second pressure. Such embodiments further comprise an incompressible fluid outlet in fluid communication with the incompressible fluid portion and a pressure relief apparatus in fluid communication with the compressible fluid portion to release at least a portion of the compressible fluid from the fluid vessel when the first pressure exceeds a threshold pressure.
