Abstract
There is provided herein, a valve for filling of at least one fluid cell of a pressure device, the valve comprising: a multiplicity of chambers; at least one elastic membrane having a varying physical property along at least one dimension thereof, the at least one elastic membrane configured to cover one or more of the multiplicity of chambers to cause varying pressure among the multiplicity of chambers; at least one membrane fluid inlet configured to provide fluid so as to apply pressure on one side of the at least one elastic membrane; at least one chamber fluid inlet configured to provide fluid to at least one of the multiplicity of chambers and apply pressure to the other side of the at least one elastic membrane; and at least one chamber fluid outlet configured to allow fluid to exit from at least one of the multiplicity of chambers to at least one fluid cell of a pressure device.
