A pneumatic pressure controller (10, 100, 200, 300) includes a body (12, 112, 212, 312), an inflation plunger (28, 128, 228), a vent (42, 142, 242, 342) and a deflation diaphragm (48A, 148A, 248A, 348) or piston (48, 148). The body (12, 112, 212, 312) defines an input chamber (20, 120, 220, 361) and an output chamber (24, 124, 224, 331) for connection of a pneumatic pressure source and pneumatic container respectively. The plunger (28, 128, 228) is biased towards a closed condition wherein it inhibits fluid flow from the input chamber (20, 120, 220, 361) to the output chamber (24, 124, 224, 331) and is movable against the bias (30, 130, 230) to allow such fluid flow for inflation of the pneumatic container. The diaphragm (48A, 148 A, 248A, 348) or piston (48, 148) is variably biased towards a closed condition wherein it closes the vent (42, 142, 242, 342). The diaphragm (48A, 148 A, 248A, 348) or piston (48, 148) is configured to move away from the vent (42, 142, 242, 342) to an open condition under the influence of fluid pressure in the output chamber (24, 124, 224, 331) when the inflation plunger (28, 128, 228) is in the closed condition and the variable bias (30, 130, 230) is sufficiently reduced, enabling fluid from the pneumatic container to egress to the atmosphere via the vent (42, 142, 242, 342).
