In apparatus in which, as in the parent Specification, two or more valves 75, 76 controlling flow from separate fluid-pressure sources are selectively operable by a diaphragm 88 subject to outlet pressure, the selecting means consists of a plate 92 having recesses 94, 95 for engagement with the valve stems 79, 80 and retained in an oblique groove 91 in a member 86 which is movable axially by the diaphragm. The plate 92, which is held against rotation by engagement with a plate 83 which is slidable on the valve stems and is itself prevented from rotating by fixed pins (not shown), is positionable by rotation of the member 86 to couple either valve stem with the diaphragm. |
