Abstract of the Disclosure A novel flow divider-combiner valve unit is disclosed. A valve body includes fluid passageway means for con- trolling fluid flow through the divider-combiner valve unit. The fluid passageway means comprises: a cavity, first, second and third passageways; first and second pressure-responsive elements; and biasing elements for retaining the pressure-responsive elements substantially in open positions until a predetermined substantial pressure differential exists in the divider-combiner valve unit. The biasing elements also enable the pressure-responsive elements to move substantially independently of each other toward closed positions when a first pressure differential in the divider-combiner valve unit exceeds the predetermined pressure differen- tial. The biasing elements additionally cause the pressure-responsive elements to move substantially in unison when a second pressure differential in the divider-combiner valve unit exceeds the predetermined pressure differential. The first and second passage- ways communicate with first and second spaced portions of the cavity. The third passageway communicates with an intermediate portion of the cavity. The first and the second pressure-responsive elements are movable in the cavity respectively between first open positions and progressively closed positions. The fluid passage- way means controls fluid flow through the divider- combiner valve unit by controlling fluid flow between the first and the second cavity portions and the first and the second passageways.
