Abstract
A hydrogen distribution valve for alternately distributing gaseous and liquid hydrogen from a tank is disclosed. The hydrogen distribution valve includes a valve housing having a gaseous hydrogen inlet, a liquid hydrogen inlet, a hydrogen outlet and a reference pressure port for receiving a reference hydrogen pressure. A rocker valve is provided in the valve housing for alternately sealing the gaseous hydrogen inlet and the liquid hydrogen inlet. A bias mechanism engages the rocker valve for biasing the rocker valve in sealing engagement with said liquid hydrogen inlet. A valve membrane is provided in fluid communication with the reference pressure port and engages the valve head for biasing the valve head in sealing engagement with the gaseous hydrogen inlet.
