    Patent number: 3935626
    Abstract: A plural range pressure regulator construction having a housing provided with an inlet and an outlet separated by a valve seat that is controlled by a valve member that is interconnected to a flexible wall carried by the housing. Biasing means are carried by the housing for acting on one side of the wall to tend to move the wall in one direction relative to the housing, the biasing means comprising a plurality of separate spring means each acting on the wall to provide one pressure range for the pressure regulator construction. The housing has a storage space for storing one of the spring means so that the same will not act on the wall whereby the remaining spring means acting on the wall will provide another pressure range for the pressure regulator construction.
